Protean 370 motor compatable flywheel cage

I've had 370 sized motors hanging around for ages waiting to be put into a blaster but I never quite found the right one to put them in. Some 370 motors are pretty powerful and would serve as good alternatives to some of the hobby grade 130 motors.
The motors are as long as 180 motors but much fatter, my thinking is that running bigger motors more within their limits will help them run cooler, they also have more mass to absorb more heat and they seem to have vents in the top to help through flow of air. All of this makes me think that they will then last longer.

So anyway to actually test these motors I need a platform, as test flywheel cages won't cut it in a nerf war, so the protean it is.

The changes I made have been to enlarge the flywheel cage and magwell to accept the larger motors, I also have been worried about the motor leads catching on the flywheels so i've added a lip on the back of the flywheel cage to direct the wires back down the magwell channels to reduce the chance of the flywheels cutting into the wire.
As I'm only running this as a single stage I filled in the second stage hole in the magwell part as well as reducing the radius of the underside of the magwell which helps it print better.
The motors covers have been enlarged and given lots of vents.

I only made one size flywheel cage which is 42mm, that should get you 130 with 27-30k rpm motors and worker wheels

For the motors look around online on places like ebay and aliexpress. The motor screws needed are m3 countersunk 6mm
