Lasercut filament spool (30cm)

I made this spool to be able to send my customers their 3D printing PLA filament with an eco-friendly spool.

100 meters will fit easily and if my calculations are correct it will be able to hold up to 200+ meters.

I do ask from you that you give me feedback if you think it could be improved ;) Ofcourse you don't have to do this!
