General precision cutter for 90º and 45º

This is a simple cutter I made for cutting PTFE tube at 90º, and printer filament at 45º. BTW it also cuts other things... It uses 2cm of standard 18mm cutter blade fixed inside the body by a short M3 screw. The pusher is attached to the body by a long M3 screw. You can mount it with or without spring, to keep it opened or closed, its up to you...

Remember to use support on both parts.

TODO: Maybe a smaller version, or an 'all plastic' version.
