T12 Leadscrew Nut holders X&Y Axis of the TopsCNC NEMA23 version
thingiverse
This is a modified nutholder for a 12 mm leadscrew in stead of the 8 mm screw used in the original design of the CNC of Topsie. It is used on the Y-axis and you need to print 2 of these. I also added a 1mm thicker version (marked with an X on the top of the thing) to be used on the X-axis. You only need 1 of this To eliminate backlash, you will need to add a nut on the other side of each nutholder,This can be a 3D-printed nut. I used this thing: https://www.thingiverse.com/thing:4511590 See https://createforcuriosity.com/en/design/9vPDR81o/details for the original design.
