Overly complex (a theme you'll notice in my models…) holder for a Kurt vice handle.
Intended to use (4x) ½" diameter x 1/8" thick countersunk magnets, with (4x) M3x6 countersunk (flat head) bolts (threaded directly into the plastic; longer will be fine but stick out near your fingers). Could also use the existing holes or the extra space to run screws directly into a wooden surface.
There's a pocket on the back meant for a piece of shelf liner or similar, to keep the holder from sliding on slick vertical surfaces - the attached .dxf is an outline of the shape.
Multiple versions uploaded - v0.002 is pictured, though v0.001 might be interesting to you as well. I also made “simplified” (just the primary features but none of the chamfers/fillets) versions of v0.002 in .step and .stl, in case you want to edit the design without those features getting in the way.
The author marked this model as their own original creation.
