OpenRC F1 Front Suspension (Updated V2)

Description Daniel's Awesome F1 Car Gets Upgraded Front Shock Absorbers! Updated Design V2 Rocks! I've been searching for a more effective alternative to NinjaFlex dampers in my suspension design. The originals just weren't providing enough cushioning. A Breakthrough Moment! While changing batteries in one of my kid's toys, I noticed the tiny conical springs inside the battery compartment and knew I had found the solution! This new design is pure genius! Adding a recessed area to the hubs allowed me to fit a longer spring from an AAA battery terminal over the guide bushings. This enabled the full travel I was looking for. The attached pictures showcase the unassembled view with the new spring, the battery terminals used, and the suspension in both uncompressed and compressed states. The springs I utilized came from these battery terminals: Keystone Electronics 5204 Contacts; Battery Spring Contacts; Negative Spring Contact with Tab, AAA, N (5 pieces) http://www.amazon.com/gp/product/B00LPP7NZ4 I also uploaded a video to YouTube demonstrating how it works. https://youtu.be/YGE2oiwUV90 And posted a driving demo with all 3 of my designs installed on the car: https://youtu.be/g154r7Dcjas Front Suspension: http://www.thingiverse.com/thing:1455120 Rear Suspension: http://www.thingiverse.com/thing:1455132 Standard F1 Rubber Tire Adapters: http://www.thingiverse.com/thing:1337521 By adding small NinjaFlex dampers to the rigid frame of the F1 car, I was able to reduce some of the bounce and vibration of the front of the vehicle as well as allow a small amount of body roll to aid in cornering. The front upper and lower control arms have been modified to allow a sliding pivot to be attached to the wheel hubs. Next, the wheel hubs themselves were shortened vertically to enable the placement of NinjaFlex (or possibly other materials) flexible spacers to act as small shock absorbers. I printed the spacers out of NinjaFlex using a single layer on all sides to make them as soft as possible. (.2mm layer height and .4mm nozzle) Thinner would be even better if you have a smaller nozzle. The key is to make them as soft as possible. Instructions: 1. Print the following: Front_Upper_BOM_Suspension Front_Lower_BOM_Suspension 2 x Front_Wheel_Hub_Suspension (One needs to be mirrored for the opposite side of the car) 4 x OpenRC F1 Guide Bushing 2 x Front_Rim_Narrow (If you aren't using the rubber tires/wheels) 2 x Front_Wheel_Narrow (In NinjaFlex if you aren't using the rubber tires/wheels) Assemble as normal, replacing BOM parts. Thread a Guide Bushing on each new longer screw and thread it into the Front_Wheel_Hub on each side. The smaller side of each hub faces up and gets one of the suspension spacers between it and the Upper_BOM. Use the photo above to help with assembly if necessary. I'd love for others to design a better/softer damper or experiment with other materials. Small springs would probably work very well too, but I wanted to keep with the 3D-printed concept. This project is an excellent opportunity and I'm proud to be able to contribute. If anyone has problems mirroring the part "Front_Wheel_Hub_Suspension," I can mirror it and upload another .stl file; just let me know.
