Speed Tank Casters/Bogies

Kudos to Bryant87! He did all the hard work on this awesome design. Thanks for the contribution!

This remix splits the casters into halves so they don't need supports. Using halves like this also allows you to play with contrasting colors for the hub portion of the caster. I've also separated the gear ring from the drive caster so you can print the gear in something tough like NylonX (The drive caster itself isn't split because it doesn't need supports). If you want to use a commercial gear ring, use this remix: https://www.thingiverse.com/thing:3245752

No supports are needed. Some cleaning of the parts is needed for proper fit. Glue caster halves. My gear ring fit perfectly when test printing it in PLA, but with NylonX it needed a lot of trimming. I'm not sure what to do for you, so I left the design as is. Expect to do some fitting of the gear ring.

CasterInner - the inner portion of the regular caster
CasterOuter - The outer portion of the regular caster
CasterTInner - the inner portion of the tensioner caster
CasterTOuter - The outer portion of the tensioner caster
CasterDrive - the drive caster to accept a replaceable GearRing.stl . Use 3x40mm bolts
GearRing - I printed in NylonX, but have zero run time on it.

Note: print an extra set of tensioner casters. As the track wears in, replace the rear caster with a tensioner caster to take up slack.

And yes, I'm using my remix
