Ultra tiny props for High Speed Propeller Launcher

I made a tiny propeller for Lukas Hannert's high-speed propeller launcher found here https://makerworld.com/en/models/628601-high-speed-propeller-launcher?from=search#profileId-553231. I made the small version of his launcher(available as a print profile on the main page), and it has the standard launch spindle size, and wanted some smaller props for that standard size launch spindle. I also have kids, so i wanted some lower cost, faster printable options. two of these fit on the standard spindle, the extended spindle could launch 4.

these are also relatively safe for indoors, they fly much slower than the standard propellers. they can still get some pepper behind them if you try, so use caution.

all that being said, use at your own risk, do not use broken propellers, do not launch towards people or animals, and by downloading this file you are taking full responsibility for the inherent risks associated with hi-rpm, tiny bits of plastic flying around.
