well i got annoyed at looking all over with no avail so iv bit the bullet and ordered 3 sheets of 0.75mm lexan (enough for 3 shells all going well) and i shall set about making my vacuum forming machine out of scrap bits.
i will let you all know how it goes success or not but if they go well i may be able to do the odd one or two.
i will be changing the design tho adding a air vent that can be cut out allowing air flow directly onto the motor for added cooling so no heat sink needed
