Spool adjustable diameter for filament samples

Needed a spool for filament samples. Tried one but didnt fit my needs, so made one where I can adjust the diameter.

Its meant for filament samples at about 50g / 15m and likewise.


Base can be printed in 0.4mm layers.
Adjustable brackets best in 0.2mm layers, to easier fit.

simple to print, but print brackets on the side, to strenghten the tabs.

Edit: 8/3-2022
Added version 2 of base and brackets. Its now a bit longer with 6 holes, and the bracket has been adjustet for eiser to brint, and with a filament "eye" to hold the end fixed.

I recommend using the v2. but kept the other one here if someone already uses it.
