Designed and printed a simple 1/2" hex bolt wrench that I can use to install and remove the plug on my boat. I ordered a bag of PVC plugs from Amazon and normal pliers damage the plastic to easily when I install them.

Designed with a snug fit to reduce the likelihood of stripping.

30% infill recommended.

Printed on Ender Pro 3:
210 for nozzle
70 for bed heating
