The aim of this set of models was to provide a modular set of workshop drawers that used the minimum amount of filament, but was still rigid enough to be effective. To achieve this I used cutouts on the chassis, and there is no fancy sliding mechanism to join the parts together (This effectively doubles the wall requirement for the chassis).

Note: All elements are designed to be printed without supports. Print the chassis elements with the back downwards to the print bed and print the drawers with the bottom of the drawer to the print bed.

The chassis prints best with a 0.4mm nozzle, but the drawers will print very nicely with either a 0.4mm or 0.6mm nozzle.

Chassis

Each chassis element has 4 cutout slots and pins that can be used to located the chassis very effectively and easily.

Then place the next chassis element using the locating pins

You can keep on adding horizontal and vertical until you have the number of drawers you need. You can then either screw it to a backing board (I use a sheet of 12mm plywood), or you can apply superglue between chassis elements (or both). Once screwed (and glued) the chassis becomes very rigid.

The middle chassis element uses the least filament and can be used for all sides. If you want a neater finish however i have included 8 side chassis elements as well as the centre element.

Drawers

I have included drawers with 3 different handle styles

• A pull handle at the bottom leaving plenty of room above for stick on labels.
• A old fashioned filing cabinet design with room either side for stick on labels.
• A version of the filing cabinet design but with a slot either side to drop in paper labels.

Each drawer comes in 1x1, 2x1, 2x2, 3x2 and 3x3 compartments, and has a nub at the back to stop the drawer from simply sliding out and will allow you to leave the drawer open still in the slot.
