Cylinder Radial Engine #3DThursday #3DPrinting

NewImage

Shared by LensError on Thingiverse:

Fully printable 5 cylinder radial engine. Use 1.75mm filament as a piston pins, it should be friction fit on the piston and lose on the connection rods. The same with the bottom of the rods attaching to the rod assembly.

Rod assembly needs internal supports, you may want to print that separate. Other parts don’t need supports.

I have modeled a little lip to the crank pin what you can melt to be a little wider so it locks the rod assembly in place. Just don’t melt the parts together!! In my case, it was not needed because they stay in place well enough.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
