Hot-Wire Cutter Accessories (fence and roller guide)

After buying one of those cheap chinese "educational" kit foam cutters I was impressed enough to add some accessories to make it a little bit more consistent and turn it from a toy into a useable tool for the small hobby workshop.

The Roller Guide requires an M3 bolt and a 7mm x 3mm bearing and is just superglued under the cutting board to provide a nice transition for the kanthal wire and keeps it at the origin.

The fence just clips over the edges of the cutting board.
