This is a remix of the BlasterforgePH Stryfe Flex Flywheel Cage - with an extra added bonus.
I printed the original and found my standard motors just fell out, even if I could get them to grab by friction, they wouldn't stay located right into the hole at the top and sat at 'a bit of a squiff'!
On the standard cage there are tabs either side of the motor which allows you to attach the included rubber retainers, these keep the motors snugged in rather nicely. I decided that this was a good idea and added them to the original model.
NOTE: The original cage IS NOT MY DESIGN (and technically, the little retaining tabs are kinda borrowed from Hasbro . . . . . . ). Less said about that bit the better! :D
Licence respects the original.
So, here you are, if this is the cage you're after then great, if not then - well, great again; thanks for stopping by.
Included in the 'remix' section is something you should also add if you're using an open cage like this:-

This provides a bit of a cover for the cage, stopping errant darts squeezing out and jamming - obviously at the worse possible time.
Have fun and happy modding.
