Summary
This is a set of modular drawers which interlock and are infinitely expandable. The basis of this design is to produce drawers that can be printed at high extrusion speeds and will fit together without tolerance issues. The system uses regularly spaced T slots with ample clearance to fit together loosely and built in springs to provide friction to keep the drawer boxes aligned. The system also uses a small beam across the top of the drawer body which acts as a drawer stop to limit the drawers travel as well as to reinforce the top of the drawer box if loaded (In practice the number of spring loaded T joints tends to distribute the load well). Larger drawers have thicker walls than smaller drawers for increased strength. The drawers are based on 1″ increments. The smallest drawers are 1″x1″ however the larger size drawers are really based on 1″+ the joint thickness.
I have already revised the design a bunch of times to make things run fit together nice and to get the slots to fit easy but hold where you place them, I will be interested to know if they work as well as they do for me for others.
One further note. This is based on a parametric model so that I could get different drawer sizes easily and control tolerances and wall thickness via spreadsheet. Based on the way it is made if you print the drawer dividers they will need to be rotated to lie flat on the printer bed. The drawers and boxes should load in the correct orientation to print.

Printed in PLA and PLA+. Sliced in Cura Printed at 100mm/s on 60C borosilicate glass covered in Aquanet hairspray. Usually the drawers fit together just fine, sometimes I get a little bit of stringing if I rush things too much but just running the T slots together a few times makes everything smooth.
