This is a remix of the large OpenScan.eu DIY low budget 3D Scanner.
The origin version had some drawbacks for me so I decided to rebuild it because:
origin parts didn't fit to my extrusion profiles because they had some places which should act as slot nut and they didn't fit
it is difficult to print because of these slot parts
no BOM was available
origin didn't use any bearings. In my opinion, especially the turntable needs some bearing as stepper motor bearings are not able to carry much axial load.
So here it is. It fits on 2020 extrusion profiles. The entire dimension of the parts fits to origin.
BOM:
3D printed parts (see description for quantity of each)
6x 500mm 2020 extrusion profiles
1x 530mm 2020 extrusion profile
2x 450mm 2020 extrusion profiles
1x axial bearing 51101(12x26x9)
8x radial bearing MF 106ZZ
M4 screws (10mm)
slot nuts M4
3 Nema 17 stepper motors 59Ncm 17hs19-2004S1
2x bar-bell discs (0,5kg for rasberry pi or 1kg for DSLR camera) with 30mm inner diameter as counter weight
The entire build works great, however the rotor is a weak point as the two motors are not able to carry the weight. So I had to add some counter weight. To attach the holder of counter weight, I drilled M6 threads at the end of the bars. This way I was able to bring everything in balance.
However, if you plan to rebuild it, I'd suggest to use geared stepper motors here. Please note that these are much longer and they needs to be attached in a different way. But if you're able to build a 3D scanner, you should be keen enough to solve this by your own.
