Pro4 SC10 headlight tabs & diffusors

The Team Associated Pro4 SC10 has a couple of issues around the front headlights, one being that the body pops up and on top of them during crashes, and the other being the excessive brightness of the LEDs when looking directly at them. So there are two models here that work together to solve these issues: 1: A headlight ‘tab’ that replaces the stock piece and protrudes up and angles back and reduces the likelihood that body pops up, and 2: A headlight LED ‘diffusor’ that covers the LED and spreads out and reduces the intensity of the light. 

Here is how the body typically pops up and gets caught on the headlights:

Then here is how the tab pieces disourage that by protruding up, angling back towards the body and even including some rubber bumpers to add friction to body slipping upwards:

The diffusors knock down the intensity of the LEDs and spread out the light a bit, making them less uncomfortable to look directly at:

The diffusors are printed from transparent white PETG (I used Hatchbox) and the tabs are printed from black PETG (also Hatchbox). The diffusors slip on over the headlights, then the tabs hook over and are pushed into place, and held by the stock M2.5 flat head hex screws that normally go into the back of the headlights.

I used these rubber feet on Amazon to go into the 10mm circular recesses, and they help with keeping the body from slipping upwards during a crash. I have found that a bit of Shoe Goo to go on first helps the rubber feet stay in place. 

In terms of printing settings, I just went slow to get good quality, and only the circular protrusion tab pieces needs supports. Other than that, both models print flat on the build platform as shown:

With some recent testing at my local indoor dirt track pretty, we did find the headlight caps broke at the tab at a layer line, so there is an updated design in the files that changes the design so it can print in a ‘lengthwise’ orientation. As shown:

The tab piece is redesigned to accomodate the new flat/square profile, but it is the same otherwise and prints in the same orientation as before. The updated design hopefully will be more robust, so testing will continue! They look a bit more cool, as the light pipe effect brings the illumination towards the backs of the pieces in an interesting way.

 Enjoy!
