I needed a simple spool holder solution for my Prusa i3 MK3S+ clone inside my open Ikea Lack enclosure. Here's what I came up with – a quick-to-print frame that attaches to the Lack and uses my favorite spool holder design.

What you'll need:

• 3D printed parts from the included files
• Your preferred spool holder (design of your choice)
• 1-3 screws
• Screwdriver
• Optional: Drill

Instructions:

Print the parts:

• Material: PLA or PETG
• Infill: 13% (triangles for strength)
• Walls: 3
• Top/Bottom Layers: 4/5
• No supports needed
• Print time: About 4 hours 10 minutes

Assemble the spool holder:

• Insert the roller pin into the roller.
• Add 608 bearings to the pins.
• Attach the assembled roller to the filament holder.

Mount to your Lack:

• Place an empty spool on the holder to gauge placement.
• Ensure the spool doesn't touch the enclosure's bottom or ceiling.
• Mark the mounting spot on the Lack frame.
• Pre-drill holes (optional).
• Screw the frame into place.

Enjoy your new spool holder!

Tips:

• The included 3MF file has optional screw holes for extra stability.
• If you need a version for a fully enclosed Lack, let me know!
