dji Firewheel quadcopter arm

A replacement arm for the dji Firewheel quadcopter.
The photo shows the version before the published one that doesn't have a hole for the motor wires.
I struggled to get the screw holes in exactly the right place, but I think they are ok now. If not, let me know. It's about a four and a half hour print on my Replicator so I haven't bothered to re-check, but I'm sure I'll be printing another soon, given my piloting skills!

This needs to be a solid as you want to make it and printed with support. I printed it at 50% fill, with two shells and it doesn't flex. It also weighs less that the original arm.
However, in crashes it does break easier than the original ones, but if you don't crash, that's not a problem.
The motor mount holes should be drilled out to 3.5mm and just replace the centre plate screws with some self tapping ones to get a good grip on the plastic.
