U1 air-tight spool holder (non-bending metal)

Hi,

I see some of you also want to fix many problems about the factory SPOOL HOLDER with one solution: spool diameter, air-tight, friction, durability, cheap, modular, etc).

Finally, I ended up at a design, this: https://payhip.com/Liko1980

Happy customizing!

That design absolutely does not look airtight.

What is it with people hawking **** for sale on here lately? First Ethan and now this - this is a forum, not a webshop? @Zoe_M

Hi, I’d like to ask if you’ve tested it with RFID-enabled filament yet, and what the results were. Does the metal overload the NFC electronics?
