Attachable Filament Dry Box

This is a 3D printable dry box that you can attach to you printer's frame with the original spool mounting hardware on Creality printers. Just check your spool size to make sure it will fit the box (some brands like protopasta use wider spools). I printed with 0.6 mm nozzle but i think I should work with 0.4 as well. You only need supports for the stand, I used tree supports under the 4 corners of the piece.

If you are using an ender 3 to print this, you need to increase your printable space in your slicer and print without brims / skirts. Make sure your bed clips don't interfere with the print as well. Here is how you can do that: https://www.youtube.com/watch?v=Il1sierB4Yk (You can skip ahead to 2:04)

Assembly:
Reuse the Creality spool mounting hardware to attach the stand to the printer (On the top brace is best)
You need 2x 608 bearings that press fit inside each half of the box.
There is a hole on one of the covers to let the filament out, you need to put a piece of PTFE tube in the hole to seal the box properly.
Place the spool and the roller inside the top half, pull the filament through the PTFE tube hole, then close the box (the smaller half should slip into the larger one).
Finally, place the cylindrical box onto the arm, if it doesn't fit in the arm, you need to realign the roller with the bearing on the second half of the box.
