Surgical Mask Strap ULTRA-Fast -Cheap -Compact!

This is a remix of the Surgical Mask Strap by Suraky:

I made some changes to make this Surgical Mask Strap faster to print, cheaper to make (less filament), and more compact to fit more on the print bed.

• Made the strap straight – I wasn’t sure how the original strap was to be worn – which side goes up, but looking at pictures online, I saw that they were being worn both ways. Not seeing any need for the curved design, I straightened it. This allowed for tighter alignment on the print bed – fit more straps on the bed.

• More openings in the strap – reduces the amount of filament being used and speeds up the printing process.

• Reduced the height – the total height reduced from 2.0mm to 1.8mm and the strap height reduced from 1.0mm to 0.9mm. This slight reduction corresponds to the maximum recommended print height of 0.3mm for a 0.4mm nozzle, commonly found on 3D printers. One less layer is printed, reducing the print time a little more.

I made some of the original straps on my Ender 3 printer. I was only able to fit 8 straps on the print bed, mostly because of the curved design. The prints took about 16 minutes per strap and used about 3.7g of filament each.

I can fit 15 of my remixed straps on the print bed, the print takes about 9 minutes each and uses about 2.1g of filament each.

I’ve included the .gcode file for printing 15 straps on my Ender 3. Do not try to use it on any other printer. Instead, slice from the .stl file.
