This is a strap designed to help release tension from surgical masks on ear. We have approached the idea from a quick printing point of view even on budget 3D printers as well as reducing material usage to create an efficient model. This will help in rapid and cost-effective production for clinical usage.

Furthermore, to decrease the hassle of constantly printing and removing, this design can easily be stacked with the guide on how to create a stackable model given below.

Material: PLA but PETG can also be used.

To create a stackable model using the guide below, you have to get Autodesk Fusion 360. You can get Fusion360 license free for a year for personal use from this link

To create a stacked version of the strap:

Download the file for the strap from this page.
Open Fusion 360 and create a new design.
Click the "Insert" down arrow (under "Solid" menu) and select "Insert Mesh".
Select the strap stl file you downloaded to insert.
On the Browser right click on the top node of the tree (should be named "Unsaved") and click on "Do not capture Design History".
A warning will pop up but click "continue".
No right click on the model and select "Mesh to BRep".
Once that is done right click on Body1 from the tree in the Browser and select "Move Copy".
On the menu that pops up select "Create Copy".
On the "Z Distance" type "1.2 mm" and click "OK" [The shield is 0.9mm thick and we add 0.3mm (equal to layer height) [0.9+0.3=1.2mm] to allow stacks].
Now you can click on Body2 repeat the above steps to create another copy.
You can finally go ahead and create as many copies as you want.
Once done right click on the top node of the tree under "Browser" and select "Save as STL" to save the version.
Remember that stacking needs a bit of a trial and error with your printer so see what number of stacks is suitable for your printer and play around with the settings on your slicer.
