if this could be added into the design it would be spot on, adds load of strengthening.

Ahh indeed this is clever but i find it a bit dangerous when disassembling. We may forget to slide the upper deck sidewards and could damage those upper supports.
Dan,
Shapeways also offers printing in alloy materials but the price isn't cheap and i have not worked out the tolerances yet. I spent a lot of time and money to adjust the bearing tolerances before I got it right. Its not as simple as putting a 14mm hole for a 14mm bearing. I had to compensate for shrinkage and those shapeways people didn't know squat about this.
Welshy, i will send you this gearbox for you to test. I will check my old email for your address, I think no change of address ?
If you have whatsapp we could stay in touch quicker. Right now we have a huge worldwide whatsapp group and Alex T.H and Dan Rowlands is in it.
I have used 3D printed gearboxes on my Optima Mid and it took punishments well. I did crack a few rear GB earlier on, but I thickened and reinforced my designs and so far holding up.
