Also, just having fun trying out a some 3D CAD and printing ideas. More versions on the way.

Print instructions

Print in PLA using the 3mf file provided. Might work a bit better without a brim, but I didn't want to risk it.

This is a tricky one to print as there are a lot of small overhangs and bridges. Even if you don't use the 3mf file, I suggest you take a look at it for all of the special settings I used.

This would probably work better with a smaller diameter nozzle (I used the "standard" 0.4mm). Might be an interesting experiment to try some time.
