Facts first: This is a remix of a print-in-place firetruck, which adds separate components for up to five colors/materials. Now for the story…
My son wanted me to print a fire truck with my new Palette 2, but the two-color version I found wasn’t printing well (the headlights and bumper weren’t inset into the main body, preventing them from attaching well). So, I remixed the original design in Meshmixer to make it easier to print, and while I was at it I split the components out for more materials.
The versions in the picture are both only three materials (copying the original rendering). One is at 100% size with .32 layer height and the other is at 40% size with .2 layer height. The larger print had some issues entirely independent of the model (the heater went off overnight, and the ensuing temperature drop caused the Palette to emit some rough splices that under-extruded due to friction in the bowden tube). Sorry I didn’t opt to reprint in higher print quality, but I was in a hurry.
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!
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.
