3DRC Upgrades

thingiverse

Update 8/12/18: Added reinforced rear hubs. Update 5/5/18: Added steering linkage. I broke this part so just decided to reinforce a bit. Update 4/28/18: Added an upgraded spur gear. This one is slightly stronger and allows you to use a set screw to fit it to a shaft if you choose. Update: 4/22/18: Added a few more upgraded parts (rear shock tower, axle, ring gear). Car is running great now! Update 4/16/18: Parts are now tested and work well. The car drives pretty well. MUCH easier to control the the openrc F1. These are upgrades I designed while building the 3DRC Buggy. I admit- I haven't run this car yet- waiting on a new battery and ESC. I'm confident all of these changes are upgrades to the car though. Everything is 'compatible' with the original design so you can pick and choose what to print or not. Parts include: 1. Tires- added a slight bulge to the sidewalls to allow the tires to flex more easily. 2. Wheels- changed from a solid disc to 4 spoke- because it looks more cool. 3. Springs/shocks- custom springs that are 1 piece to print. You can make them thicker thin to adjust spring rate. Print some 3mm ID spacers to get them to line up straight. Front shocks need to be a bit shorter than rear. Scale them to the length you want and you can adjust ride height. 4. Rear lower control arms- made them easier to print and added clearance for rear shock mounts. 5. Pinion gears- made the ID smaller to fit 2mm shafts. Also made them taller to increase strength. 6. 3mm spacer. Scale this up or down as needed. I decided to use some of these to help align the shocks. 7. Rear shock tower- strengthened 8. Rear axles- strengthened 9.Steering link R- strengthened 10. Rear hubs- strengthened I'll probably add more parts as I break things and decide they need improvement.
