Hi there! Thanks you so much for this project. It's very educational.
I've tried to 3D print and skip order a hardware kit. But I would like more information about the L10 pulley in the kit. What boar/size is it that match a 214L belt? It might be printable right?
Im living in Sweden and I have searched high and low to find "Metric key stock 2mm x 2mm" and "Keyed Rotary shaft 8mm"...I can order from McMaster-Carr but 100$ in shipping is not very cool.
Has anyone find a supplier in Europe? Or a different solution to the problem of having those?
The "Keyed Rotary shaft 8mm" is difficult to get in europe. I have been looking for it quite a while and the only source I found was: https://www.raptorsupplies.com/pd/keyshaft/8mm-gks-1045-300?web_source=DE&web_medium=header+country+flag (free shipping, at least to Germany...) In the end I used a normal rotary shaft and modified it a bit, so that the setscrews do the rest. Not the best solution, I guess but I could not convice myself to pay the price...
What the hell! 50 euro for it? No way. I had problems with both the j3 bearing-holder and getting those tiny m3 threads properly on the spindle so Im experimenting now with a complete 3D printed, skipping the 6mm shaft all together and with a T10 pulley on the end joined with m4 screws. No idea if its gonna work but.
Looks interesting but I am not sure if it will handle the force. There are some fibre enforced filiaments which might do the trick.
Ah good idea
