Product Description

No choosing. No overthinking. Just great filament and a spool worth opening. 

Every order is one full 1kg, 1.75mm spool of brand-new, factory-sealed 3D printer filament, chosen at random from our USA-shipped lineup — for a flat $20 with delivery included. You find out the brand, material, and color when it lands, and that surprise is exactly what lets us price premium American-shipped filament below shelf.

It's the lowest-risk way to try a new material, test a brand before committing to a case, or simply keep the print farm fed for less.

Up to $39.99 retail value — yours for $20, shipped.
Single 1kg spools from these brands typically sell for $25–$40. Delivery is already included; nothing extra is added at checkout

What might be inside — the brand pool

Every spool comes from one of three American-shipped filaments we stock for their consistency and clean winding:

Ambrosia — "Filament of the Gods"

Premium, Grade-A virgin filament with AMS-friendly cardboard spools sized for the Bambu Lab AMS with no adapter. Strong across everyday PLA and Silk right up to engineering-grade PC-CF and glass-filled ASA.

Push Plastic — Made in Springdale, Arkansas

A workhorse manufacturer extruding 100% virgin resin in the USA with tight ±0.05mm diameter control. A go-to for makers and print farms who want reliable, honestly-priced filament across a deep material range.

3D-Fuel — Fully US-made, NatureWorks resin

Manufactured in-house from prep to final inspection. Known for Tough Pro PLA+ (up to 8.8× tougher than standard PLA+) and Pro PCTG — a near-isotropic upgrade over PETG with better UV and chemical resistance.

Possible material types

  • PLA — the everyday starting point. Easy, reliable, great for models and prototypes.
  • PETG — the workhorse. Strong and durable for functional, end-use parts.
  • PCTG — tougher and clearer than PETG, with better chemical resistance.
  • ABS — heat-resistant and tough, built for enclosures and hard-working parts.
  • Exotics — the wildcards: silk, matte, carbon-fiber blends, glow and more.

Why makers keep buying it

  • Below shelf price — premium US-shipped filament for a flat $20 shipped.
  • Try new materials risk-free — discover a PCTG or silk you'd never have bought at full price.
  • Feed the print farm — cost-effective fuel for prototypes, jigs, and general printing.
  • Unboxing that's actually fun — every restock becomes worth opening.

Who it's for

Makers who love variety, hobbyists after affordable filament, print farms needing dependable stock, engineers testing a brand before buying a case, and anyone who enjoys great value with a little surprise.

Compatibility

Every mystery spool is 1.75mm — the standard for Bambu Lab, Prusa, Creality, Elegoo, Voron and most FDM printers. Filament is hygroscopic, so drying before use is recommended.

Frequently asked questions

Can I choose the color or material?
No — the surprise is the point, and it's what keeps the price this low. Selection is random, and multi-spool orders may include duplicates.

Is it really a good deal?
Yes. These brands typically retail at $25–$40 per 1kg spool, so $20 with delivery included is below standard shelf price on nearly every outcome.

How fast does it ship?
Ships from the US within 1–2 business days, with delivery already included in the price.

Can I return it?
Because contents are random and filament is hygroscopic, opened spools can't be returned for change of mind. Confirmed manufacturing defects are replaced — just contact support.

A little mystery. A lot of value. Add a Mystery Spool to your next order and let CONSUM3D surprise you.
