Every Mystery Spool is one full 1kg, 1.75mm spool of brand-new, factory-sealed filament from our USA-shipped lineup — chosen at random, for a flat $20 with delivery included. You find out the brand, material, and color when it lands. That surprise is 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 keep the print farm running 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 included; nothing extra is added at checkout.
The Brand Pool
Every spool comes from one of three brands we stock for their consistency and clean winding:
Ambrosia — "Filament of the Gods"
Premium, Grade-A virgin filament on 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 domestic 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 Materials
- 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.

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. $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. Delivery is 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.
Every spool is 1.75mm — compatible with Bambu Lab, Prusa, Creality, Elegoo, Voron, and most FDM printers. Filament is hygroscopic; drying before use is recommended if the spool has been stored open.
