Rear bumper-mounted LED lights for Traxxas Rustler 4x4 VXL

I've seen plenty of front LED mounts for the Traxxas Rustler 4x4 VXL, so many. But get this… this one is for THE REAR

Which is surprising given the many mounting points one could use. That said, this is held on by a single M3x25 cap head screw which you will need to supply :^)

-------------------------------

4/23/2024 UPDATE:

One nagging issue is the bolt holding the bumper on to the bottom. If you send it off a decent jump and land butt-first, you're going to eventually pull the screw out, leaving the bumper hanging by the wires.

The version 1.5 model aims to reduce this by adding additional fastening points above the bumper - the two screw holes inside the oval part of the bumper. I would recommend this part if you like to bash or hit jumps and land like an idiot (like I do.)

-------------------------------

I gave it as much meat connecting the screw to the mount as I could manage without risking bashing the bottom of it into the ground during wheelies or at the bottom of shock travel. Three zip tie anchors of dubious utility and two highly-likely-to-break integrated wire guides are included but feel free to edit those out or just clip 'em off.

This was made with those RC LED kits you find on amazon with the screw-in silver shrouds included. The LEDs inserted into those will need some sort of glue or extra help to hold them in long-term wise, I don't trust the friction fit at all.

Wire management is up to you, but there are so many options on this chassis it shouldn't be too much trouble.

Materials

😊👍 PETG - WAS Recommended. Part pictured was printed in Inland translucent blue PETG. The middle of the road material for okay strength but not brittle.

💪💀 ABS - Probably better for strength, even more better at stinking up the joint and giving you lung disease.

🤷❓ ASA is a thing - I don't know what it is or if you should use it for this. Please let me know if this is a good idea or a bad idea. 

😑👎 PLA - Sure, it will print in PLA. I feel like anything PLA on a basher like this will not survive.

🤔💭 TPU at 100% infill could be interesting.

UPDATE: TPU IS THE CHAMP, ESPECIALLY IN COLDER CLIMATES

PETG looked fantastic but turned out to be too brittle for the winter months. TPU is far and away more resilient. 

Any layer height is fine. 

Use whatever settings work for your printer and material, here's what I did for what's in the picture.

0.3mm layers
Bottom 3/Top 3
4 walls
50% infill
