This is an exact copy of @Ivo-tje's multiboard cylinder, except it has a critical code issue fixed in the scad which fixes the size of the push fits to actually work with Multiboard.

Original descrpition: 

So you printed the multiboard and need a round container?
Got cottonpads to clean your printbed? A can of compressed air? Measure, customize and print it! Use snaps to attach it to the board.
