Brick Storage - Magnetic, Modular Storage System

Go check out my latest model, free for a week!

This is a collection of modular, magnetically-sealed storage boxes based on the building block design popularized by LEGO. It is a fairly easy print with no supports required. Additionally, all printable parts fit within 180mm x 90mm, meaning it can be printed on an A1 mini or any similar small printer.

Bricks The following bricks are included:

4x2 - 180mm x 89.5mm 4x1 - 180mm x 44.2mm 3x2 - 134.7mm x 89.5mm 3x1 - 134.7mm x 44.2mm 2x2 - 89.5mm x 89.5mm 2x1 - 89.5mm x 44.2mm 1x1 - 44.2mm x 44.2mm 1x1 cylinder - 44.2mm x 44.2mm

The dimensions of the bricks are slightly offset from what would be expected to account for clearance between bricks and to stick with the ratios of actual LEGO bricks.

Magnets You will need small 6x2mm magnets. The tolerances are fairly tight for inserting the magnets to prevent them from falling out and you will need to press fit them. If you have trouble getting them in, you can use a pair of pliers. One trick I've also found is to partially insert the magnet, then flip the brick over and press it against a table so it gets pushed in fully. If the magnets don't fit, you can scale up all parts by around 1-2% for looser tolerances.

Make sure you insert the magnets in the correct orientation so the lid snaps on even when rotated!
