stackable filament storage spool box with PTFE connection

I designed a filament box suitable for all 1kg spools. It prints without supports. The boxes are stackable, both upright and on their sides. The top and bottom shells simply slot together, as does the snap closure. The connecting pins for attaching it to other boxes can be glued in place. I printed it with translucent PETG to show the filament color. In this version, I have added a PTFE connection. For the connection, you will need a 4mm pneumatic fitting with an M6 thread. This allows you to connect the box directly to the printer. (see pictures) Furthermore, I have adjusted the position of the seam. Only glue the small connecting pins into the top shell. Glue the large connecting pins only to the left side of the top and bottom shells when the snap closure is facing forward. A TPU gasket is included in the print profile. Enjoy your new box!
