Gridfinity cylinder box (customizable)

I couldn't find this simple box design when I was setting up a gridfinity organizer for my aquarium supplies, so I made it and put it up for others to use. Based on https://github.com/wromijn/openscad-gridfinity-block. Use the customize button on makerworld.com (does not work in the Handy app), or download and run the OpenSCAD (params at the top of the file). Instead of boosting me, donate to charity!
