Hardware Required for Assembly:
M4x12: 8
M4x20: 2
M4x35: 4
M4 Thin Hex Nut: 14

Any thin hex nut should fit right into the model, but the ones I had on hand were 7mm across the faces. I printed the feet and the cradle in TPU but there's no need to. Best Results were 1.2mm wall thickness with 45% infill for the TPU parts.
