Can't stop doing craft projects? Want to turn your filament boxes into something useful? Or do you just like the cardboard aesthetics? Here is a model for 1x1 Gridfinity bins which works with 2 mm thick cardboard commonly found in filament boxes.

This one takes around 4.7 g of filament per labeled bin, regardless of height, since the middle part will be made out of cardboard. It's only around 50% less than the plastic one, so I would go for the original model for small batches or if time is limited.

(Remix: Took the top and bottom sections from https://makerworld.com/en/models/50848, changed the label shape)

Assembly Guide

1- Print the top and bottom sections (duh).

2- Extract a “cardboard plate” from your filament box. Make sure it's not damaged. You can try to make the sides square at this stage.

3- Draw this shape using a ruler (or with a CNC plotter if you have one?). The height depends on the bin depth you want. It's a good idea to stack this drawing if you want to make multiple bins.

Try to draw the vertical lines along the cardboard's grain. That will make folding a lot easier.

4- Cut the shape.

5- Score (don't cut!) the cardboard along the lines. Only cut the top layer of paper.

6- Remove the top and middle layers from the last strip, leaving behind only the back layer.

7- Fold the shape using the scored lines and glue the last strip to the first part.

8- Fit the top and bottom pieces. Depending on luck and your crafting skills this should be a tight fit.

9- Fix the top and bottom pieces by gluing the corners.

10- Voila!
