The desk-in-the-basement printer

How we pack a spool
Four steps between the extruder
and your build plate.
We ship the same spool to a first-time hobbyist that we ship to a small print farm. The process below is why the box you open next week prints the way this week’s did.
- Step 1
Extrude & measure
Every batch is measured at four points around each layer of the spool. If it drifts outside ±0.02 mm the run is set aside before it’s ever wound.
±0.02 mmdiameter tolerance - Step 2
Wind to net 1 kg
Spools are wound to a net 1 kilogram of filament, not gross weight. What’s on the label is what you can extrude.
1.00 kgnet weight - Step 3
Vacuum seal, day of winding
Each spool goes into a heat-sealed foil pouch with fresh silica the same day it’s wound. No humidity between the reel and the bag.
Day 0reel → seal - Step 4
Print the dry-time card
A card in the box records the seal date and a recommended dry-cycle for that specific material and colour — no guessing.

Who we’re for
Small print farms, classrooms, and desks that need spools that just work.
Classrooms
Teachers running a room of Enders
Consistent diameter matters when a dozen students are all pushing print at once. Standing orders and school POs are fine — email us and we’ll set them up.
Small shops
Making parts, not just prototypes
PETG Tough is the reason most shops order from us — enclosures, fixtures, brackets, and parts that live outside on a hot day without turning to soup.
Our house rule: if a spool doesn’t print well on our own Prusa and Bambu machines in the workshop, it doesn’t go on the shelf. If it does, we tell you the temperatures we used and clip a printed dry-time card to every bag.
Ready to spool up
Twelve colors on the shelf, boxed the day you order.
Browse the full range, or drop us a line if you’re running a classroom, a makerspace, or a small production shop and want a standing order on flexible terms.
