This is a custom designed part that protects your ears from the straps of face masks. The design similar to other designs roaming around the internet; I wanted to create one that optimized utility and print time.
I have printed a couple hundred of these and gave them to friends and family in the healthcare field where they have been able to distribute them to their co-workers. I printed all of mine in ABS so they can easily be cleaned and sterilized.
For optimal print speed using a default 0.4 mm nozzle, print with a layer height of 0.35 mm so each strap only requires 3 layers of material. Each one of mine printed in about 13 minutes.
The .3mf file and the .gcode are both ABS material AND they set the printer to sequential printing. Note that in order to fit many of these on the print bed, the extruder clearance is set to 0 mm under the output options menu. Otherwise PrusaSlicer will give an error for the parts being too close. Before you print this way, you need to verify that the PINDA probe is far enough from the bed when the extruder is all the way down. If you need to adjust the PINDA probe, make sure to reset your Z-offset/first layer calibration.
Because I printed these in ABS, I brought my printer into my garage to avoid the fumes and I covered the print bed with Magigoo. I also created a barrier around the printer to prevent drafts. The Magigoo lasted for at least 5 prints before I had to clean the bed and reapply. It helps if you let the bed cool before taking the print off as the Magigoo will stick to the bottom of the print if not completely cooled first.
