Sbox From Prusament Cardboard Box

One day I've noticed that Prusament boxes have similar width to walls of Sbox printed on my Prusa MK3S+. I really like recycling projects and I'm in love with these cardboard filament boxes. For years I've used organizers from here: https://www.printables.com/model/58986-prusament-box-storage-system-v2 which are great, but I also wanted to have something compatible with Gridfinity. However, the interior dimensions of Prusament box are not optimal for this system's grid, unless you cut the lid tabs off. 

I designed Sbox with cardboard walls that is able to fit 5x4 Gridfinity base. The frame needs about 65% less filament than the regular Sbox of this size would need. It's bigger than small Sbox but smaller than the medium one.

Printing

Please be aware that this is a hardcore bridging test. It is designed to be printed without supports to save as much filament as possible. With the right settings you should be able do get a really neat print.

Cutting the Prusament box to size

1. Open the box and mark a line 18 cm from the front wall parallel to it. Cut through the side walls.

2. Unfold thin piece that you cut through and cut it off.

3. Remove the remaining piece of the tab you cut off to make room for the new one.

4. Add new creasing line by pinching the cardboard with a blunt tool and fold the back wall. 

5. Mark the points where the side wall corners meet the back wall and cut off the excess.

6. Fold the back wall along the new creasing line, inserting the tabs into the gaps in the side walls.

7. Carefully insert the box into the printed bottom frame.

8. Add some hot or super glue between the top of the frame and press it firmly till it dries.

9. The top is pretty straight forward. Cut the lid of the box to size of the top frame (17,9 cm x 21,9 cm) and glue it to the lid frame.
