This model was made to keep my PTFE tubes from my dry boxes tamed. I like the idea of keeping my filament dry and capped when not in use. I was having an issue with the tangled mess of the PTFE tubes that were awaiting use. This allows me to mount the plate to the wall and slide the tubes into the caps for a neater workspace. There is also a hole above each cap to place a sample of the filament that is in that location for quickly identifying what is hiding inside of the PTFE tube.
I modeled this in FreeCAD and printed with PETG. There are holes to nail it to a wall or you can use adhesive on the flat plate.
The author remixed this model.
I have placed 6 of the caps on a plate to be mounted to the wall.
