Hand Held Hot Wire Foam Cutter
thingiverse
This is a six piece hot wire foam cutter frame. 2 x pieces make up the handheld part. 3 x pieces form one of two prongs of the cutter. 1 x coupler ensures a tight fit between prong pieces. Print three prong pieces twice to get two required pieces for both prongs. Four I-shaped connectors are printed to ensure the tightness of the prong pieces. These can be glued in place for permanency or left unglued. To make the hot wire foam cutter complete, you'll need the following parts: Nicrome wire Insulated electrical wire A DC power source (a single 18650 Li-Ion battery is fine) An on/off switch (a momentary press switch installed in the trigger position works well here) A dimmer to adjust power delivery and heat of nicrome wire for cutting. Two <5mm screws, four washers, two nuts, and two wingnuts to secure nichrome wire.
