I have tried few versions online and at the end I decided to make my own design which is big enough, has the spool that can rotate for small and big labels, designed so you can pull to you or down, space for clamp, cover that fits in the hole and the tunel that does not create so big pull force but it will also not suck the labels inside. I have made like 5 versions to test it.
This is the clamp I will use to hold it in place https://www.aliexpress.com/item/1005004827679866.html?spm=a2g0o.order_list.order_list_main.5.15281802QL402u . Double sided tape or nano tape should also work.
Printed with no supports. 0,35 layer is OK with 0,6 nozzle. Material PETG. Hexagon spool not tested.
