Wanted to add Prop guards to my X-Star drone, but didn't want them mounted during transport. I found some DJI Phantom 3 quick release guards on eBay and made the adaptor mount so these can be used on the X-~Star. The design allows the re-use of the original screws.
I printed these flat and added support for the slots, but maybe better printed vertically??
Used clear M-ABS filament so that the LED would illuminate the plastic and still be able to view the orientation of the drone.
The guards can be found at: https://www.ebay.co.uk/itm/DR90-Quick-Release-Snap-On-Propeller-Props-Protector-Guard-For-DJI-Phantom-1-2-3/142242448307?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
These are not mine and I am not affiliated with these people, just pointing in the direction of where I purchased.
Added second version that will print vertically and also added a bulge to help with seeing the light at a distance.
Might be worth experimenting with the orientation of the print, as it is a pain to remove the support material.
