Universal Filament Stretcher - Filamentrollenspanner

Hi everyone,
this is my Construction of an universal filament roll stretcher. You can use it to fix every normal filament spool with holediameter from 50 up to 90 mm.

It was a lot of work so pls show me if you like it and press the like button.
I would also appreciate a small donation :)

Other important knoweledge:

I printed all parts with PLA and 0,1 mm Layerhigh. Greasing the parts is recommended.

I use the following screws and parts to build it:

12x M3x16 Screw
12x M3 Nut (and washers if you want to run it easyer)
3x M2x20 Screw
6x M2 Nut

6x tension spring 5,5 mm x 25,5 mm

Perhaps I optimize the construction to use just one bigger spring, because its difficult to assemble all the springs :)

Maybe I will design an holder for the Anycubic I3 Mega so that we can use this Universal Filament Stretcher with a fixclip and some ballbearing to run it very smooth :D

Hope you enjoy this Thing and don´t forget to hit the like-Button. Thanks.
