Complete set of 3d printable part files for the enclosure

The STL file names indicate how many parts are to be printed, including if they need mirroring. e.g. ‘Hinge A x2+2M.stl’  means you need to print 2 normally and 2 mirrored.

The design is for a complete enclosure for the Tevo Little Monster and uses ¼" (or 6mm) twin wall polycarbonate roofing sheet. You will need a 1Mx2M sheet. I used this for the doors too, but if you need good visibility, the front door panels could be made with a clear ploycarbonate of acrylic sheet instead of the twin wall.

You will also need some 3mm dia. steel rod for the hinge pins. This could be from 3mm round wire nails. The finished length of the pins is 40mm. so 2" nails would do.

the individual parts for the frame are bolted together with M3 x 12 pan head screws & nuts. The polycarbonate sheeting is also bolted to the hinges with the same size screws. You will need 24.

The frame and hinges are attached to the TLM with M4 x 10 CSK screws and M4 captive nuts. You will need 44.

I used Duct tape/Gaffer tape along the joins of the poly' sheeting. This was the best solution after trying folding it, even using heat, without success!

For printing the parts, no supports are needed. The maximum overhang angle is 45deg.

I used PETG,

0.2mm layer height

4 wall loops

20% infill

4 top/bottom layers.

I also used a 5mm brim with 0.05mm gap for the ‘Hinge B with door ribs’ and the ‘Door top closing return’ because they have small areas of bed contact.

Take note that the Door top closing returns are printed with the large flat area on the bed, so it doesn't look like the brim is need. However, there is a small area that is only joined to the main body after about 12mm printing height! Hence the brim.

The ‘Top M frame x1’ is a special piece which allows the bed wiring to pass into the enclosure at the top of the Z upright where the wires normally run. Wires are then inserted into the innermost side nut slot of the extrusion. They emerge at the base and are covered by the ‘Hot bed cable cover rev1’ part.

Hope you find this helpful, especially when using the printer for those tall prints! This enclosure, along with my 3 Arm effector, allows a full 330mm dia. by 500mm high part to be printed.
