Spike Collar

Attempt to reproduce a old-school spike collar I came across. It is likely just as effective as the original. It uses the locks in the link below (requires 2) to secure in place. If more time was spent I could have eliminated one but, due to skill and time(lack of) I just made symmetric.

It requires alot of printing but makes for an effective toy. You will need to print
2 x the top files (4 total)
2 x inside keyhole
6 x inside screwhole
4x middle
and many spikes. You could make your own here to help re-size.

It requires a few screws and nuts to hold together all can be picked up locally at the hardware store. You may need a little sanding and will need to dremmel the spike in the keyholes or you can cut out in the stl before printing. Was just easier for me to do the first.

Also I used the graduated infill in cura for the tops. The tabs are not the greatest and need some higher infill to prevent them from breaking off. All can be printed without support. Also so
