4mm PTFE Cutter Guide

Although heavily inspired by Andow's PTFE Cutting Guide, I drew this one from scratch and made a number of optimizations. Foremost is the use of a more print-friendly font which is also recessed in to the print, incurring only one filament swap. I used a silk silver to contrast the black - this is a thin element so similar or translucent materials may not show up well. Beyond there I added in three holes for 5x3 magnets (which are optional). These press-fit in with a pair of pliers and for my print and my magnets at least, do not require glue. If you do not have parallel pliers big enough to achieve this cleanly, you can always protect the print with some thick paper or card stock (I actually used the backing of a BBL spool refill sticker) so your pliers don't mar the surface of the print. Other changes are just general chamfer/filets that improve ergonomics.
