Electronics Stack Screw Standoff for Usmile 220mm/5" Freestyle FPV Drone Frame Kit

I normally hate uploading such simple designs, but this will hopefully save others some problems when assembling their Usmile 220mm Freestyle FPV drone frame kits.

This is a simple 7mm standoff for the electronics stack screws. The provided screws are M3x30mm, which is 7mm too long to fit underneath the top cover of the frame. Simply insert them on the provided M3x30mm screws, then screw them into the bottom of the frame and top with a nylon M3 nut.

M3 washers should also work for this purpose, but a 7mm tall stack of M3 washers adds a bit more weight than I wanted. 4 of these standoffs weighs about half a gram. Recommended to print out of ABS for shock resistance, but PLA should hold up as well.
