Filament Straightening Block

A two-piece block for 3D printer owners that holds softened filament straight while it cools, so you can use it for hinges and axles.

It has five channels and comes in one size. Hold the halves together with two rubber bands, feed in filament softened in hot water, and leave it to set for about half an hour.

Available in many colours, including multi-colour and magic sparkle. Send us a message after you order to choose yours.
