IKEA Billy Complete Filament Storage System / Rack

Spool Holder Brackets

• Various print profiles for the most commonly available conduits/pipe/solid rod sizes in DIY stores. I found 20mm conduit to be the most accessible and cheapest option in the U.K. but users in the U.S. said that ½"conduit (21.34mm outer diameter), ½" EMT pipe (17.93mm) is easier to get hold of, and I also dowel to be a reasonably affordable option so added 19mm (¾") dowel rod profile. A less favourable option is 19mm copper/stainless pipe as it is relatively expensive but I added this profile after someone requested it.
• Design of the bracket eliminates gaps at the end of the rails where spools might get stuck!
• Perfectly spaced for full use of the entire cabinet. Left & Right brackets clearly marked.
• No screws necessary! Print the push-in serrated insert pins which can be removed later if required with a flat blade screwdriver!
• Includes tool for marking out additional holes as required.
• Includes over-hinge bracket for the lower section - print one (left or right depending which side your door hangs). See image.

Swatch Holders / Labels

• Snap-Fit, just like the brackets.
• Print the holders first (40 per cabinet) and then print the swatch/label. 
• Holders snap-on to the spool holders.
• Slide the labels in from the side (snug fit, won't fall out).
• All label types included - just copy/paste to the printing plate as required. 
• Label includes border frame, so it appears to be one piece! 

Humidity/Temperature Sensor Bracket

• Holds the two common types of round Humidity/Temperature sensors. 
• Two bracket types for either standalone mounting in-between the spool holders, or pin them into the spool holder itself.
• Rotate to angle the gauge so it can be viewed easily.

Silica Dry Box

• Slides in on the middle and lower shelves with just enough clearance underneath the spool holders.
• Comes complete with push-in feet to improve air flow underneath the box.
• Slide-in lid for secure and easy access.
• 4 boxes fit side by side (experimentation found that larger boxes were clumsy/heavy when filled)
• Look out for future updates, planning a fan add-on to improve airflow/dehumidifying.

Door Latch

• Keeps the door tightly closed when used with a rubber seal.
• Screws to the side of the cabinet*
• Captured nuts ensure consistent tightness!

     *Each door latch requires 1 x M5 50mm Bolt, 1 x M5 Nut, 2 x M3 35mm screws. I contemplated      adding a template to the print profile, but the hole positions will be determined by the depth of      rubber seal/gasket you use around the door.
