MPCNC F Z motor plate with bolts

thingiverse

This is a modified version of the MPCNC Z motor plate, model F 25mm. I created it because my original F-Z motor plate kept sliding off even when tightened down. So, I thought it should be secured to the Z pipes like the spindle and other components are. Using OpenSCAD, I imported the original model, sliced it into three parts, stretched the middle section, then reassembled them (that was version one). Unfortunately, this design covered up more of the motor shaft, making it impossible to access the screws for the coupler. To fix this, I carved out a bit from the side around the motor to approximate its original size while leaving a thicker area around the shafts. I also removed the M4 hole and nut shape from the thicker design so that the bolt could pass through. Two M4 x 50mm bolts are required for assembly. The original F marking remains on the design. This script can be used to modify the object for the C and J versions, but since I don't have anything to test them on, I haven't designed for those variations. The creator of the original F Z motor plate is welcome to take this mod and incorporate it back into their design. For reference, the original STL file is included in this post so that the script works as intended. Note that quick OpenSCAD renders may appear poor, but a full render will produce a better result for STL export.
