In our edu-makerspace, we use a lot of CleverMade collapsible bins to organize our tools/jigs/supplies. At the end of the year, we did a simple laser cutting project where we made leather patches for baseball caps. With this project came a need to start storing a new class of creation materials in a bin - leather dyes, conditioners, leather itself, etc.
The dye we purchased was Fiebing's Pro Dye in 4oz bottles. Rather than have these bottles rolling around loose in the crate, I decided to quickly model and print this holder to keep the bottles we have - and the ones we are going to get - more "contained and controlled" within the crate itself.
