About small filament spools
Small spools of 250 g or 500 g are a cheap way to try a new material or brand, or to get a colour you only need for one print. Many come in packs of several colours.
Per kilogram, small spools cost more than 1 kg spools, so this page sorts them by price per kilogram to show which are the best value.
Common questions
What is the cheapest filament on small spools right now?

This page lists the cheapest per kilogram first, and prices are re-checked through the day.
Which materials does filament on small spools come in?
In stock on Amazon UK and Eryone UK right now: TPU (22), PLA Silk Dual/Tri (14), PLA Glow (8), PLA Silk (5), PLA Wood (5), PLA+ (5), PLA Matte Dual/Tri (4) and Nylon (3).
Do I need a hardened nozzle for filament on small spools?
For PLA Glow and PETG-CF, yes: our material data marks them as abrasive, and abrasive filament wears out brass nozzles quickly. A hardened steel nozzle lasts far longer.
Are small filament spools good value?
Per kilogram they usually cost more than 1 kg spools, but you pay less up front and waste less of a colour or material you won't use again. For an everyday colour, a 1 kg spool is usually better value.
