You need buildable models first. I've never seen someone take the time to make a model of the walker in solidworks or anything similar.
Thats true, the cost of the plastic thread for 3d printing extruder type enough for a Amiga Case I wouldn't want to waste... So yeah best to model it best, perhaps clay?? Then you would be able to make changes, get precise measurements then translate that to your CAD designer. Very small designs then you dont care so much about wastage..
Would be even more elegant if you had a teflon powder/laser 3d printer or injection mould
