The Bat Symbol on the wheels are the icing on the cake! Shared by Canino on Thingiverse:
No supports required. You could rotate the body and point front up or down, to get a smoother finish on the curvy lines. But that way supports are probably required.
I used 15% infill for wheels and shaft, which could probably be lower.
For the body i used 20%, but i think 30% would be better. I already have a slight crack in one of the wings (son crashed it into original lego batpod).
Sand the ends of the shaft before attaching the wheels. I made a left and right wheel because of the tire profiles (yes…OCD).
I eventually used an extra piece of lego as a seat for the minifig, as this made attaching and detaching it easier (couldnt find a black piece)
Edit: if your wheels dont spin freely use one of the “rear fix”spacers
Depending on orientation or printer settings your batmobiles wheels could spin a bit jaggy (as they did on mine). The original shaft runs completely through the body and print residue could make it spin jaggy.
I am new to making “functional” designs and will edit my future designs a bit with this in mind.
Rear fix2 should be a bit narrower fit. Try one of them, clip them a little bit and glue on.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
