Pocket Caltrop

prusaprinters

This is not a toy. Do not create if you have children or pets or are liable to leave it lying about the house.Print two of these parts.Feed a screw through each diagonal hole.Push two parts together with the screws pointing outwards with one half at a 90 degree angle to the other.Optionally thread a fifth screw though the holes in the middle of each block for added strength. Notes for modifying:Use openscad to modify files.If your parts fit too loosely, decrease the “grip_tolerance” value in the .scad file. If they are too tight to clip together increase this value.“screw_head_depth” should be adjusted so that when the outward pointing screws are in place, the heads should lie just outside the edge of the hole through the middle.If using nails, you should still use a screw through the centre as this helps hold the parts together when thrown and also helps spread the weight through the caltrop. Slava Ukraini!
