Acrylic Scoring Knife / Plexiglass Cutter

Acrylic Knife is a compact and ergonomic 3D-printable handle designed for cutting and scoring acrylic sheets using a standard acrylic cutting blade.

The handle provides a comfortable grip and precise control when making straight scoring cuts in acrylic, plexiglass, polystyrene, and similar sheet materials. Its curved ergonomic shape reduces hand fatigue during repetitive work and allows accurate guidance along rulers and straight edges.

The design uses a replaceable acrylic cutting blade secured with two M3 screws and nuts, making blade replacement quick and inexpensive.

Perfect for makers, workshop users, model builders, and anyone working acrylic projects.
