ABOUT KATREG LABS
Made for makers. Built on consistency.
Katreg Labs is a European filament brand. Every material in our range is chosen, specified and tested for one thing: prints you can repeat, spool after spool.
Every spool is held to a ±0.02 mm diameter tolerance, every batch is checked before it ships, and every colour — like our recyclable kraft packaging — is built in from the start of production.
Tools are nothing without the people who create with them.

THE KATREG SPOOL
Designed down to the spool
Built-in fill gauge. Markings from 1 kg down to 100 g show how much filament is left at a glance.
Open windows. Check the level and colour without unwinding a single loop.
Known spool weight. About 140 g empty — weigh the spool and you know exactly what's left.
Filament end holes. Lock the loose end in place so the spool never unravels.
Kraft cardboard. Recyclable with paper — less plastic in your workshop.
