Gridfinity 3x4 Caddy

A very simple Gridfinity carrier for bins, etc., with a combined total width of 3x4 units. Will allow 17 cm of stacked height.

I printed the bottom plate and sides in PLA and the handle in PETG. You can improve the durability with a drop of superglue between the sides and the bottom plate. The handle will snap into place and should not require any reinforcement.

Note that this design is not intended for heavy lifting, but will handle your average, “moving things from the floor/shelf to the desk”-type duties, so do not fill it up with bins full of fasteners. The pictures show a weight it will support without issues.

Two things to note when printing: 

1. The print profile has modifiers for improved strength around the tabs and notches.
2. The side plates are not ambidextrous. I have marked one plate with an X to match it with the side of the base plate marked with a matching X.
