These are designed to fit into gridfinity boxes that have already been printed. 

Hi there! I have decided to publish these for peoples use, they are for my tools that i have designed them for, but i thought it would be useful for others to make use of them aswell! 

I find them useful because it is not an independent print, meaning that it is separate to the gridfinity bin. This means that if you ever need the bin or you loose a tool, you can still use the bin by taking the insert out. 

To install i use a TINY amount of hot glue, only to stop rattling, otherwise it should be fairly tight, especially with the bins that have internal lips.
