Replacement prop guard for Eachine x73 - UPDATED V2! These are best if the "fingers" print as just walls, so adjust wall thickness/shells to allow for zero infill - 1.6mm/4 shells if you are using .4mm nozzle. If printing in ABS I suggest scale 101% Motors will be a tight fit, but they should fit. Dont worry if the motor hole dosnt look round - its not, its an octogon, allows for a nice tight interference fit. [v1 only!]I found it is best to "pre-drill" the screw holes - i use a heated .5mm stiff wire.  Screw holes should be dead center in each ear. Impact testing (v1) video here https://youtu.be/YGDEtD9yTf4 V2 improvements: Reinforced finger base. Pre-printed screw holes (no hot-wire drilling) Also see a version with more protection at a slight weight penalty here Printed Replacement Prop Guard - Rounded Please upload a print if you make a set, Follow if you like the design!
