this is kind of a multi-design project i have been working on, primarily 2 versions, one with a 030/180 motor from the scx24, and going to eventually finish the 280 motor size.
my first venture, started with a base of another person's design then upgraded where i thought it could use it i.e. rear suspension and motor sled, bearings, non-slider servo steering rack.
Main goal was to utilize parts from models i had. SCX24 motor and gearing, hardware for axles, etc. tires would be the exception.
this was the initial design that did not include suspension.
in the picture below you can see the motor plate from the scx24 installed, this had to be filed away a bit as the "spur" gear in this case is actually the internal transmission gear. a 3mm nut on a 3mm shaft worked perfectly to mount it to the 3mm diameter, with 3mm thread turnbuckle (steering link?) i had laying around.
used a set screw on the rear wheel hub on the left to fasten the wheel to the shaft.
had a very difficult time with the wheels on this one (going to utilize micro z tires) as i felt it necessary to utilize bearings, and the only "hardware" i had a available were m3 shoulder screw, i believe shock screws from a T-Maxx.
ended with a split rim design to "capture" the bearing into the rim which can be screwed to the hub.
overall it feels pretty solid, was quite difficult to design the rim with enough material to be structurally sound, but also not just being a plain dish wheel. I'm sure i will be revising as i go to make them look better chamfer-ing or fillet-ing edges, possibly go for a 3-spoke if that doesn't look to weird. a few cases of the design not having enough material to even register as a layer in my print slicer.
i really wish i had learned about the revolve command probably would have been much easier.
Design with rear suspension:
i had a few stock scx24 shocks so wanted to be able to incorporate those, TBD on the spring weight though.
the design:
most likely will need revision as it is not really desirable layer stacking for strength in the rear shock mount location.
as it sits now. waiting on tires, and the rx/esc from my scx24 decided to give the ghost, so waiting on a replacement for that.
Thank you for reading and as always welcome advice/tips!
