CAUTION! POINTY PARTS! PLEASE BE CAREFUL WITH THIS PRINT!

I highly advise taking caution (especially if there are children, pets, or stupid adults in your house) with this if you print it. Do not accidentally leave this on the floor unattended, so as to not step on it, as the pointy bits may injure you despite being plastic. Think of the pain of stepping on a Lego brick but it's a spike.

The Caltrop is an Ancient Roman area-denial tool. Dropped to the ground, a tip is always pointed upwards. This is because a caltrop is basically just a tetrahedron.

This was remixed because I noticed a small number of vertices on part of the original uploader's model seemed messed up from a corruption or something. This has been fixed.

Due to the simplicity of the model this can be easily scaled up and down to your heart's content.
