For other pegboards, universal hooks must be designed.

It is a remix of https://www.thingiverse.com/thing:2757562 because my Livarno living pegboard has slight differences. First I thought to modify, then to use universal hooks, then to make it parametric and finally to add a probe box.

The Stl provided is for the popular model M-830B, rebranded by many manufactures, for example COATI MI193120, The FreeCAD file is provided, just play with parameters to suit your multimeter, If it is not enough you can modify the objects.
