For the filament storage/dry box you will need an IKEA SAMLA (45l/12 Gallon) box, a wooden broomstick and 16 small woodscrews (2 nails are optional).
If you just want to store and dry a few rolls of filament, you can just print 4 endcaps and 4 of the cap1 models. Than cut the broomstick to size and you are good to go.
If you want to print directly out of the box you might want throughholes for the broomstick on one side like I did. This way you can easily add two more rolls of filaments for printing without messing with the box. On the backside you will need 2 endcaps and 2 cap2 models. Drill a hole at the end of the broomsticks and you can look them in place with a nail (cap2 already has holes as well for this purpose). On the front side you just use 4 times the cap2 model. For feeding the filament to the printer you may use some PTFE tubing. I just drilled 8 holes but that is not optimal.
The drill guide fits inside the indentation of the SAMLA box on each side. I just used 4 random woodsrews (4times) to attach the caps.
I also added some spacers for between the filament rolls and the side walls.
