Bolt on jam plug/dance plug for roller skates

thingiverse

This is for hex bolt with 5/16" 13mm head, it should work for most roller skates that have bolt-on toe stops, but you will need bolts with head diameter of 13mm. It's best with a hex type head so you would just screw it in without tools, just bare hands.I bought mine hex bolt from a hardware store, it's 5/16" 18(UNF) but mind the length, it should be shorter than the one it came with the skate. I bought 7/8"(22mm) and it is still touching the boot when fully screwed, so measure the length you'll need.Also I would recommend TPU for the plug, I printed it with TPU 82A with 100% walls instead of 100% infill to ensure it's 100% solid so the hardness would stay 82A.
