Modular tea organiser / drawer system

An attempt to organize tea bags in my kitchen cabinet. The idea is to build something modular and extendable. The solution should make it possible to hold both tea bags and loose tea of any kind (thus drawer design). This is just the beginning of the system - single and double frame, drawers for tea bags and the linking element. 

The joint was not yet  tested. I will post real pictures once I finish printing at least few elements of the system

Update 06.03.2023:

After printing the first set of single frame and drawer I've noticed that the tolerance of 0.3mm was a bit too small for my printer, so I've increased it to 0.4mm and added some spacing to make sure that the drawer runs smoothly in the frame. I've updated STLs and the source files
