This 4 way Octopus hook is designed to fit over the thumb screws (optional) and/ or fit anywhere on you Skadis board.

This is designed for resin printing, but it should work out with FDM as well. It is for light use. The hooks that go into the skadis board are vulnerable to snapping off under excessive force.

I printed this in resin with 2.1mm walls.

If you're going to use FDM I would recommend at least 25% infill.

I would suggest spray painting or using alcohol inks and then clear coating when finished printing.
