"Dogbone" magnetic AMS PTFE Guide

I needed to pin the PTFE tube for my AMS down to stop - or at least reduce - the filament catching in the buffer. I had a chunk of steel I salvaged from a broken kids' toy attached with magnets, but I decided to try and make a print to do it instead using the same magnets. The ends are custom sized for the 3/8" x 1/8" round neodymium magnets that I had on hand, and they fit very nicely if you add a pause at layer 19 (assuming you're printing at the standard .2mm layer height with a .4mm nozzle) with the print taking about 14 minutes total on my P1S, as long as you remember to put the magnets in instead of wandering off to make dinner for the family like I did! There's a 5mm channel running between the two magnet “feet” that should allow most standard 3D printer PTFE tubes to slide through.
