Hi guys,
Update: I got my C24 back in action with the help of a pinion gear puller. I swapped the pinion gear off the 2spd gearbox motor onto the stock motor and then installed the stock motor in my 2spd gearbox. There are holes that fit the smaller stock motor in the gearbox from the factory, so it's easy. Long story short, the front body mounting posts are a weak spot. If you mount the cage to the stock frame rails you likely won't have the same problem. One of mine broke after 4 hard hits right on the body. I used hot glue to fix the broken post and ran a bead of hot glue down the front and back side of both to strengthen them up a bit. The new version has reinforcements built in but I would suggest also adding a bit of hot glue or some other sort of glue to beef up that point of failure.
Updates are: Stronger body mount posts on the servo tray and a battery tray that installs between the chassis rails at the back end of the car (if you use plastic rails, not stock). The servo mount screw holes are smaller now so they can actually be used (sorry about that, I use 2 sided tape to install the servo and I didn't check those holes until yesterday).
BTW, the stock motor installed in the 2spd gearbox makes the car quite a bit faster, so if speed is your thing, that might be the mod for you because the gears are much beefier than the ones in the stock transmission.
If Thingiverse is as slow for you as it is for me, consider looking for your 3D parts at Cults 3D: https://cults3d.com/en/users/WrenchToDrive/creations
This is a rock bouncer(ish) mod for the WPL C14/C24. There won't be a run video any time soon because my two speed motor is cooked and my my stock transmission has a busted gear (see my bumper crash test video). The parts are on a slow boat from China which is destined to be even slower thanks to the widespread overreaction to a certain virus. Can you still buy toilet paper where you live? #ThingICantPrint
There's a much swankier 1/10 scale version of this project coming (for use with SCX10 axles) but it's a lot more work so hang in there.
Anyway, the frame sides (cage) can be bolted to the stock frame rails but the ends of the rails will stick out some. If you go that route you'll want to use the "chassis spacer" between the cage and the frame rails. The plastic printable rails are bendy but the whole unit is pretty stiff so I think it will work fine. The servo tray is shortened and there are multiple shock positions available if you use the plastic rails. You'll need some M2x10mm scews to put it together. I used brad nails and glue for most of the cage braces and it's pretty solid, but I would suggest screws for the chassis attachments for sure. The rear hinge is a little goofy but it works. That's on my list of "what was I thinking", but it won't be addressed until another day.
