DEX210 Screw-Type Wing Mounts (+Other Parts)
 

I decided my DEX210 is a keeper - It is cheap and performance is decent... but there are plenty of things I would do differently on the car - so why not actually change them?

First of all, the wing mounts. Body clip systems for wings are far from ideal imo: Bad fit (often has too much play) and every now and then you see a car with a half-attached wing because a clip flew off. I've made a design that is 100% compatible with the DEX210 wing mounts:

I had some issues with the first one that arrived - one measurement was 0.5mm off (the one of the bottom mounting holes), so I couldn't get the top and bottom screws in the holes at the same time.

Now it's solved, I've got some pictures:

Good news: The wing mount fits perfectly this time! It's a nice, rigid piece too! The wing is tightly clamped on the car, it feels much better than the sloppy, wobbly unit that's in the kit. It's also supported slightly further back and over a larger area than with the stock unit, and the top cap (which is already painted black) is really convenient - it's easier to hold and harder to lose now the two sides are connected as one piece.

You may also note the small sidepod bodymounts I have made. The sidepods are just a bit low for velcro, and the body is so tight the wiring on mine lifts up the sidepods a bit... But not anymore! :p It can be used instead of the center rear clip, in combination with it, or just the center rear clip, in which case the body posts prevent the body from lifting up at the sides.

They look good mate

Nicely done !!

Put me down please for 2 wing mounts & 2 sets of body mounts please !

Brilliant 1 wing mount in black please

Thanks guys! :D I don't currently have a VAT-number/company, but by the sound of it I should look into that! :)

...even more so as I have plenty of models lying around, from DEX210 Screw-type wing mounts to suspension hangers/blocks for the Tamiya Dyna Storm, and there's more to come :p

Awesome work dude. I'll have some if your gonna produce them?!

Looks good! How come you didn't just cut the lugs off and drill the original though? Would be nice to see this wing mount but 10mm higher than kit to get clean air to the wing without the shock tower/shocks blocking it so much.

Lovely work as always
I like the way your designs use straight forward thinking and good strong design
I will take a wing mount set pleases
Pay pals easy dude

Thanks guys! :) I'll look into making this available...

...and also in a higher version. The nice thing is that, being 3D printed, it's easy to make customized pieces without adding much to the costs of the final product. So a +8 or +10mm version, or one with the mount supporting the wing further back is very easy to do!

As for not using the existing 210 mounts: There is not much beef there to hold screws in, so if you even manage to get holes in there for M3 screws the wing mounts will likely damage soon around the screw holes (elongated holes or even tearing/breaking apart). This also gives the opportunity to make better support for the wing (with big flat areas around the screw holes) :)

I like the idea of some higher ones

I edited the model a bit :) The height is adjustable from anywhere from the kit height to say +15mm (above that I'd say structural integrity becomes an issue without redesign):

I might edit it slightly so there is more material going down from the back to the lower mount - just to ensure it's just as strong as the standard one.

That's a great idea!

Also are the Sidepod body mounts production ready at all? Would like to get a pair of those?

The sidepod body mounts like the wing mounts are not race-tested yet. However, the parts fit, they have plenty of meat on them and considering the same material is tough enough for suspension arms, I'm comfortable with it that the design doesn't require changes to go in production.

That said, I need to inform myself about getting a VAT-number and the important details involved in doing business internationally before I take any orders - I just don't want any nasty surprises with the Tax Administration :) (Not to mention I want to ensure the mods find my thread to be in the right spot on oOple)

Having a VAT number (in the Netherlands) is no problem. Just visit the KvK (Chamber of commerce), sign up as a one-man business and you are good to go.

A business bank account is not even required. Just be sure you keep track of what you do and what you sell, thus you will need some kind of administration. And keep the VAT separate and eventually pay your taxes :cry:

If you need help in any kind, I'm here to help you out.;)

Product looks great, I don't drive a Dex, but to me it looks like a nice addition. I normally drill my wing mounts as well, but without enough material around the screws they snap easier.

You can't just sell parts out of your basement with a paypal account?

In fact that's pretty common. It's even legal to sell stuff until a certain level has been reached. Going for a VAT number is safer though. :thumbsup:

Haha ok - good to know. I might do a first batch before getting a VAT number then (assuming that legal limit is not below 400 euros?). I have some health concerns that may postpone that for a few weeks, but I really can't wait to get a little business going :)

Nice to see your design work coming to fruition love the smooth looks of your stuff
Ill take some 8 mm ones dude
Awesome

Rather than selling individual mounts , wouldn't it be better to offer a kit consisting of the various sizes of wing mounts and a pair of body mounts ?

Would it be possible to mould them all together on the same tree style mould ??

I'll have two full sets when you get them up and running please !
Can you do them in different colours by any chance ??

I like them, i dont drive a durango but still a nice product! With regards to the +8mm ones, could you not use your original design, and just add an 8mm spacer? Include the spacer in the kit, that way you dont have to switch between mounts?

Like i say, nice product either way, and i like the white!! :thumbsup:

Thanks guys! :D

@Graham: It's a very cool idea to have a set on a tree, but unfortunately 3D printing is (still) too costly to put any waste material in there for the sake of being cool :lol: The way things are looking now, the sales price of the +8mm mounts will be 14-17GBP.

The current design is too large to be posted in a Jiffy Bag, so I'll also make a version with two parts that fits through the mail box - The 3D printing allows such flexibility to offer loads of options and versions, so why not make use of it? :)

As for colours, The material is white as standard, and can be dyed or painted. The dying ensures the material has the same colour throughout, but I have no experience with it (yet). Painting (only tested so far with Tamiya PS paint) doesn't go throughout the part, but adheres very well. With the white material, it's possible to take virtually any colour, including Fluorescent colours:

@Tom3012: Thanks for the suggestion :) I have my concerns it'll compromise the strength of the mount. The spacer may also have a considerable amount of material in it, and as such may be costly on it's own. I'll look into it though, it's an interesting idea!

Just a suggestion, didnt think of it that way... Possibly do 4mm increments? You could even do it so the 8mm spacer isnt solid, but uses three posts, 2 to the current holes and 1 to the rear, although a slight change in the original part would be needed... Sorry im getting carried away! Wish i had the knowledge and skill to make these kind of parts myself :p

Is this still being worked on? I would love to get the wing mounts and the side pods.

In fact, yes I have worked on this. Since late October, I've managed to test it plenty of times, of which several times indoors. In the last race I was even using a 3mm thick wing (which I think don't have to explain sends most of the impact forces straight to the wing mounts)...

It's held up perfectly! Now I must make a comment take I also made TLR22 screw-type wing mounts for two cars, and last indoor race I saw a pair break. They were about 4-6 months old and held up well so far, but when the car was lying upside down on the straight someone ran into the car at full speed and both mounts snapped in two at the same spot. So they can break, but to be fair accidents of such caliber reduce the chance of survival of other parts on your car, too :lol:

Anyway, back to your question. I'm ordering 3D printed parts regularly, so just send me a PM and I'm sure I can include it in the next order.

Just a note on the one-piece wing mount I have now: It does not fit in an envelope, making postage expensive. Therefore I'll also be offering a two-piece version, which will be cheap to post (and a little cheaper to produce, too).

Would it not be an idea to make the bottom of the screw hole flat? So when you eventually strip the thread (which will eventually happen......) you can just drop a longer screw in and have a nut on the bottom........

When that happens I would either insert a helicoil, or put in a hole from the start where you can insert a nut... That said, I quite like the idea, I'll look into it :)

Yes, a 5.5 mm slot (some 8th use this I think) or a hex shaped recess would also work well.

I'm not so sure that helicoil is the sort of thing that most racers carry trackside..........

Many people don't even seem to know the existence of helicoils (and I didn't until just over a year ago) - they're great, but with few people carrying them I best either incorporate them before selling the part, or add a slot for a hex nut (the cheaper and easier option) :)

To update everyone on the situation, this is what the revised mounts look like with the slot for the M3 nut, and of course the two-piece mount (which mostly retain the look of the original mounts):

http://i65.photobucket.com/albums/h2...sDEX2101-1.jpg

Your mention of helicoils has made me think about just buying an M3 kit, probably under €10 on ebay.
Then i can reinforce threaded joints that are regularly used. Things like lower shock mounts, transmission cases, bulkheads and so on.
Saves binning the plastics after a dozen or so uses.

Nice design but why don't you make 2 piece wing mount with required size adaptor mounted on it? so people can add or subtract the adaptor with vary screw length.

Because with that construction I cannot guarantee the durability: The spacer extends the 'arm' with which the screw applies force on the mount, thus increasing stresses, making the mount less durable. I can reinforce the mount - to a degree - but with that added material and the spacer a second mount is not that much more expensive anyway.

On an unrelated note to your post, I forgot to mention that the wings are a straight fit from the standard mounts, no modifications required (not even bigger or smaller holes than standard)!

I would like to order a set of the +8 wing mounts for my dex210 are they available yet? I have paypal funds waiting:thumbsup:

Hi m8

you should get some of these done for the Belgium GP, you will definitely sell them their, see you at the GP
