This is a completely modular customizable rack system for gridfinity drawers.
Please check out the overview page here to find the complete list of all currently available components.
This page contains all the required stl files to print a set of test parts to check the dovetail connection.
Print all the parts with the provided profile and try to fit them together. A little bit of force is required to join the parts together.
I used the back of a scredriver to lightly hammer the parts together.
If you can get them together in this way (with a little bit of force) you are good to print all elements of the system.
