after trying out some ones from thangs and thingiverse and having them fail at the pin end, I designed this one to be egonomic and have a custom pin pressure fitted or glued into the top.
I printed with 2mm layer height with matte PLA from Bambu.
you will need to scale it up potentially to a Z height of 11.5 cm
The pin I'm using is a roll pin from chamption with an outer diameter of 3mm, this allows for paper to be slid down the roll pin opening and then quilled.
Hopefully some will sell at markets! (My wife is also a fan)
