2x5KG SUNLU reel for IKEA KUGGIS

Storage Solution for 2 SUNLU 5kg Spools (55x150mm inner hole)

Required Hardware:

• 1x IKEA KUGGIS box (32x32x32 cm)
• 4x 608 bearings
• 1x M6 threaded rod (33 cm)
• 5x M6 nuts
• 2x PTFE tubes
• 1x 6mm wood drill bit

Assembly Instructions:

Drill the Holes:

• Drill 6mm holes in the middle of the side walls, ensuring the spool sits high enough from the floor. (Remember, the floor is inserted from the inside and takes up some space.)

Prepare the Box:

• Assemble the KUGGIS box.
• (Optional) Seal it with silicone if humidity is a concern.
• If needed, use the rod to pretreat the holes for a better fit.

Insert the Bearings:

• Insert the 608 bearings into the spool reels.

Prepare the Rod:

• Screw one M6 nut onto the threaded rod and position it in the middle.
• Slide the reels onto the rod from both sides.
• Secure each reel with a nut (ensure it's not blocking the bearing movement).

Install the Assembly:

• Insert the rod through the center of both spools, ensuring they unspool in the same direction.
• Place the assembly inside the KUGGIS box.
• (Tip) For better control over the heavy setup, use something like a spare piece of rod as a handle by passing it through the holes on the sides of spools.

Final Adjustments:

• Align the assembly with the holes in the box and pass the rod ends through.
• Secure with a nut on each side.
• Insert plugs and route the PTFE tubes.

Notes:

• The inner hole of a 608 bearing is slightly larger than the M6 rod. I've experimented with tubing to reduce the gap, but my cheap bearings performed worse than simply sliding on the metal rod.
• You can try using for example an electrical tape to improve the fit.
• In my case, both spools rotate freely, and the extruder force required is similar to using a standard 1kg spool on a regular holder.
