I really liked the original idea but sadly it was to small for my scale and tablet.
So I hopped on Fusion360 and recreated the design by Mirco. I attatched the slides with 3m double sided tape for now but also added screwholes if the tape isn't sticking .
The author remixed this model.
3mf file has 250 mm length sliders also includes f3d file with parameters to easily edit to own needs
