Modular Mount Clamp

Modular Desk Clamp. As long as the trapezoid locking piece fits the mounting clamp trapezoid locking piece then you can mount whatever on it. I made a sample wire guide.
Fits on overhang gaps of less than 25mm in width.

To make the locking piece there was a gap of about +0.3mm around the trapezoid locking faces. This accounts for expansion on my printer so may be different than yours.
(Sketch show is for the male side of the trapezoid locking pieces)

The screw is an M10-1.5 x 20 to exact specification (Allen key to fit an M8)
The threaded hole is oversized by a diameter of +0.8mm to account for expansion. This is tuned to my printer to may not work on your printer.

Supports were used on only the mounting clamp part.
