Núm cửa dạng spool Prusament cho Ikea Lack

Wanted to use this very cool prusament looking like door knobs. What was missing was a proper way to mount it on my acrylic sheet without a clamp like design.

So I remixed the original part. Front part of the spool as well as the filament itself is from the original design. The back part of the spool was remixed to fit the spacer as well as a M3 bolt which is hidden after final assembly. The nut on the other side of the acrylic sheet has space for a M3 nut. 

For a 3mm acrylic sheet a M3x20 bolt will fit best.

It can also be mounted by using a wood screw into the furniture.
