About this 3D model
Mounts for the original metal spool holder that fit onto the side of an IKEA LACK table. Requires a couple of M3 nuts. The only support needed is around the recessed hole on the flat side. For that simply use paint-on supports like so: Feel free to copy and tweak the original model on onshape (onshape is web-based and free!).
