Ultimate Filament Spool Holder

This is my ultimate Filament Spool Holder ;-)

Remark: Only the Filament Spool Holder is my design. All other parts in the photographs are only for illustration and are not designed by me. But I don't remember the sources. If one feels that I should reference his/her design please let me know and I will be glad to add the reference.

I have tried many different solutions to hold my filament spools. All had some benefits and also disadvantages. So I designed this one myself. It is very strong, uses a 200 mm long M8 threaded rod, a M8 lock nut, two M6 screws and two M6 t-slot nuts to be attached to the t-slot of my Felix 3.1, Felix TEC4, TEC4.1 and with two standard M6 nuts also to the original spool holder of the Creality Ender-3 V2 printer (see picture). Since it has a flat mounting surface it can also be attached to many other printers/positions including a wall. Just use the relevant screws.

On the M8 rod there can be used many available adapters and attachments as can be seen
