CNC Table Toothed Toe Clamp

I needed more toe-clamps for my CNC table. The ones that came with it are injection molded using some variant of PA15-GF (Nylon with glass fibers). This is a good choice, but I still have some Prusament PC-CF. This is a stronger material than most PA15-GF according to the charts here: https://help.prusa3d.com/materials, which I hope will make up for the fact that FDM printed parts could be weaker along the layer lines than a similar injection-molded part.

This design incorporates some of the design goodness from the toe-clamps that came with the printer, but also include a toothed design on the foot (?) which will hopefully help it hold wood stock more securely.

My design includes changes in the height of the “toe” so that no matter which orientation the clamp is in, the screw holding it down will not be on the same layer as the toe (see the section analysis image for a better idea of this. Note that the layer where the screw rests is 2.5mm higher than the toe's layer).

The cost of making these with Prusament PC-CF is NOT lower than the cost of buying the injection molded ones from a manufacturer, but, I can print these in ~1 hour if needed. Besides, this is a great starting point for more custom designs to address any project's needs as they arise.

Strongly recommended print settings:

• Prusament PC-CF
• 0.2mm layers
• 100% infill
• Organic supports to hold the bottom screw ledge up. The teeth do not need supports.
• Good adhesion on your build plate
• Draft shield or enclosure.
