This is a remix of another modular drawer. In this remix I tried to make interlocking easier and simpler. I printed this with i3 MK2S with 0.3mm setting. It works flawlessly.

Those who are interested can copy and change the design from here: https://cad.onshape.com/documents/b8ee4af07cf285982d36fca1/w/55a84582e81afb61bf916c75/e/bbc3287be67450f9c5704a6c (I use onshape.) No scaling needed for print. Just print as is.

For drawer handle I just made it simple and used a zip tie.
