Filament Box 4l with PTFE slides

Required for the spool holder:

• 2/4mm teflon tube

Required for the guide:

• M10 Male Straight Pneumatic PTFE Tube
• 15mm drill or a step drill

Required for the hygrometer:

• Hygrometer
• 2x M2,5 x 5 screw 
• 2x M2,5 nuts

I have changed the model so that PTFE tubes can be used instead of the ball bearings. This also provides a little more space in width and height for some spools.

I also constructed a guide through to the bottom of the box because the box is above the printer in my case.
A holder for a simple hygrometer can also be screwed onto the guide.
