I like printiq's foam cutter! To make it easier to print I split it in half and added pins to align. The original designs channel for the razor blade mount was too small for the 8x32 bolts I had laying around so after my first print I increased the size of the channel to accommodate a wider array of shop bolts. I also increased the depth of the razor blade channel so that it can be fully retracted while not in use. The original model left a few millimeters of the razorblade hanging out while fully retracted.
The author remixed this model.
Spit model with added pins for supportless printing.
Wider blade mount screw track for use with a wider variety of hardware.
Deeper blade channel, the blade can now be fully retracted while not in use.
