Making sheetfuls of Ear Savers #COVID19 #LaserCutting

A laser cut version of the surgical mask straps (or ear savers) was made in a very timely fashion. MSRaynsford posts:

A few days later I saw this viral post from Charlie Swift, who was collating 3D printed straps for the Leicester General Hospital. He had an ambitious goal of 1000 straps so I offered to chop up a sheet and made him 150 straps in just over an hour to get him close to his goal.

Turns out all the straps went down well and the other local hospital, Leicester Royal Infirmary now would like a batch. Given that the laser is so much faster and I just took receipt of more polypropylene sheets I offered to cut all 1000 this time. I made a few tweaks to the design to make it faster for cutting (svg here) and I also optimised them onto a half sheet of material (svg here).

The first step towards optimising a sheet is figuring out the best way to stack the design and then working out roughly how many will fit into a sensible sheet size.

See the process in the post here.
