Proxxon MF70 CNC Conversion Fix for Bubblegum

thingiverse

I'm still working on the part, as I need to fix the face plate on the back. You can use the parts now if you install the original Proxxon plate on the lower axis's back.\r\n\r\nThe original files for the lower axis are off center on my MF70. I created a new motor assembly that works with the Proxxon screws, just like the originals.\r\n\r\nv2 Changes:\r\n* Added Nema 17 mount and ensured it is centered with the ball bearing pocket\r\n+ Thicker adapter measures 4.5x5mm\r\n\r\nThe shaft collar and the M5xM4.5 adapter require M3x10 screws and M3 nuts. Use these until you have your mill set up, then make your own.\r\n\r\nThe preview image looks rough because it was printed with a 0.6mm nozzle at 0.3mm layers. For the final print, I recommend using a layer height of 0.15mm to 0.2mm with a 0.4mm nozzle.
