Planar movable filament holder (straight and curved)

I designed a new filament/spool holder for my IKEA LACK table enclosure.

The problem was, that when you use a filament guide within the table-top, then the filament might get stuck if it is not straight above the guide/hole.
So i decided to design a spool holder, that will move where the filament is pulling it ;-)

To build this you will need:

• 4x 608 bearing, I prefer 608-ZZ or 608-2RS
• 1x Igus W10-40-10 (linear slide)
• 1x Igus WS_10_40 (linear guiding)

You can also just let it stand on the base plate instead of mounting it to a linear guide!
