Needed some bicycle bottom bracket plugs for work, one is for 24mm spindles and the other is for 30mm spindles. There’s a recess for a 10x1 magnet on the bottom if you need to stick them to your work stand or bench when not in use.

I print them with the handle up and use tree support. Laying on the side has created some tolerance issues with slip fit.
