Storage rack for 0.14L Really Useful Boxes

I had quite a few of these cheap storage boxes so made a rack for them. (https://www.reallyusefulproducts.co.uk/uk/html/onlineshop/rub/b00_14litre.php)

The design was inspired by the Ikea Samla storage rack and the model by Thors Designs at https://www.printables.com/model/1154729-ikea-samla-68l-storage-rack

Decoration

To make a otherwise functional item more decorative, you can:

1. add colour changes in the slicer
2. switch filament live during the print
   • If you do this, be careful! 
   • This is what I do using a Prusa MK3S+, not sure how  it works on other printers. Snip the filament, wait for it to run out, then change the filament. Once the new filament is extruding, clear the poop. Hold a wire brush near the nozzle before pressing ‘changed correctly’. This should catch the first squirt before the printing continues. 
   • I found this a useful way to test random bits of filament.

The picture shows the second method.

I made this as 2 rows of 3 boxes (ReallyUsefulBoxRack-2x3.stl). There are also files for other layouts, but I haven't tested these.

Update

By request, I've added racks for 1x4, 1x3 and 1x2. Happy to add other sizes if needed. The 1x4 won't fit on my printer.
