Current model is for 25mm bars. For other bar diameters, adjust “d_bar” in OpenSCAD file, and maybe “l_screw” and “ep2”.

It prints on Prusa Mini. Use PLA or PETG. Increase the number of walls (both perimeters and bottom/top). I used 6. Infill 30%. No support.

With the current dimensions, additional hardware required:

• 3x M10 screws, 30mm length
• 1x M10 large washer
• 2x M10 wing nuts

Despite the large dimension of the wing nut, it may be hard to tighten enough by hand so that there is no slip at all. An additional 1/4th turn with pliers should help.
