Face Shield Visor with Bed Adhesion Tabs

UPDATED:
2020-06-05 - I converted the tabs to a style that tears off easily with a little twist or flush cutters. The other style breaks off well in Cura, but not in some other slicers. Also, this style of bed adhesion tab doesn't create a sharp edge along the person's head, reducing the cleanup afterwards. Note though, the 3mf project files are setup for a 0.6mm nozzle, so if you have a 0.4mm nozzle you will need to change your layer heights (75% of your nozzle width) and line widths (115 to 150% of your nozzle width). I just upgraded my extruder to a direct drive Bondtech BMG-M w/ Slice Engineering Magnum Hot End and man it makes a HUGE difference to my print quality. PETG doesn't ooze as much with direct drive and I'm using a lot less retraction.

2020-05-08 - The first 50+ of these printed well with only a little sticking of the band to the visor with the original STL, but I changed to a cheaper PETG and even with a lot of calibration work, it still liked to stick too much
