IKEA 365+ 10.6l drybox filament passthrough

I use the IKEA 365+ box with 10.6 l capacity to store the filament spools. I designed a filament pass-through to easily switch between filaments. Special feature: 24mm x 24mm sample holder and filament end cap / cover. Works with 4mm PTFE tubing. 

Hint:

As a spoolholder I use ikea-365-filament-dry-box-spool-holder (not part of this project) but with a modified roller (part of this project: see STL files) because I had some problems with some spools which are to wide.

Instead of buying “PC4-M10 PTFE Tube Quick Fitting Connectors” (you will need two of them) you could also print some alternatives like tapered-thread-bowden-coupling-pc4-m6-pc4-m10 (not part of this project) or my design (part of this project: see STL files).

instructions:

Use the drilling template and a 10 mm drill bit to drill the holes in the IKEA box by hand first. Do NOT use the machine! The template will wear out very quickly. After pre-drilling and removing the template, the machine can be used. 

The printed front is screwed to the back of the box with a fitting through a hole in the box. Do not tighten completely yet. The sample holders and the two stopper holders point downwards. Then mount the other side in the same way and screw both sides together so that the front lies against the box.

Prepare two 8 cm long PTFE hoses (one for each spool). Insert the tube into the connector on the back part and thighten it with the nut.

Insert the filament into the PTFE tube and guide it outwards. It may be easier if a PTFE tube is attached to the outside of the fitting. Remove the outer tube and use the plug to cover the end of the filament.

print instructions

general:

I used PLA(+) with 0.4mm nozzle and 0.2mm layer hight

parts:

• filament_passthrough_front
  Simply print it out as it is to be used later. No support or brim is needed. Even if the thickness is very small, this is sufficient as there is no load. The 24mm x 24mm filament sample holder and the holder for the stopper ensure bed adhesion.
• filament_passthrough_back
  should be printed on the back side without support. 
  I activated the 
  “external perimeters first” (visible in expert mode)
  in Prusa slicer.
• tube_connector_nut
  printed in “normal” direction / thread is facing upwards. No brim or support. Print it two times for each filament_passthrough_back part.
  I activated the 
  “external perimeters first” (visible in expert mode)
  “seam position: random"
  in Prusa slicer.
• filament_passthrough_plug
  Print it onto the bed with the thicker end facing downwards. (2x)
  I activated the 
  “brim: checked” (defaults to 5mm brim)
  “external perimeters first” (visible in expert mode)
  “seam position: random"
  in Prusa slicer.
• filament_passthrough_drill_guide
  Print it on the back side with the holes facing upwards. No special settings but 
  I activated the 
  “external perimeters first” (visible in expert mode)
  in Prusa slicer anyway.

add-ons:

• spoolholder_roller
  should be printed with the rim on the upper end
• pc4-m10_PTFE_tube_connector
  no support
  I activated the 
  “brim: checked” (defaults to 5mm brim)
  “external perimeters first” (visible in expert mode)
  “seam position: random"
  in Prusa slicer.
