Summary

My wife & bought 2 of these quadcopters from Sam's Club this week. After a few crashes & spending some time looking for this little quad after it crashed, I decided to see if I could design a propeller guard for it. I used this model for layout reference: https://www.thingiverse.com/thing:979878

This weighs .089oz with 20% infill of PETG & takes less than a half hour to print. You do loose a little power with this added of course, but that also makes it easier to learn to fly starting out. It is a pretty snug fit on our quads. I would check it after each flight to make sure it is still not interfering with the propellers. Printing this in a bright color makes this small quad easier to find on the ground. You could also print this with out the raised guards if you just want to be able to find it easier.

I included the openscad source & a STL file. You can adjust a few variables, but it might take a little playing around with the numbers to change it. I still need to file off some of the plastic artifacts from the arched propeller guard sides.
