This is a spice rack I designed to fit both my cabinets and the build plate of my Ender 3 Pro. If you have a larger printer, feel free to use the step file to resize it to your needs. The slots are sized to fit common Spice Island brand round jars, and Kroger/Target brand square jars. This is a pretty minimalist design to keep the used plastic weight down, so the edge jars are not completely supported (I would recommend keeping any square jars on the inside.

On coarse settings should be about a 23/25 hours print. I would also recommend printing on the back face (the one with the hole cut-outs).
