I made these drawers to help me organize small electronic components, such as LEDs, resistors, transistors, etc. When I have time, I plan to make 1x2 and 2x2 drawers to store larger items, such as the Arduino Uno development board. The dimensions of the drawer box are 4 cm x 7.3 cm x 2.6 cm. I used 0% infill for all my prints, because I don't need these drawers to withstand a lot of weight.
