Layer by Layer: 3D Modeling Robot Arms #3DThursday

On this weeks layer by layer, we take a look at how to build Adabot’s robot arms for 3D Printing!

Adabot 3D Printed Robot Toy from Adafruit

boxes1

Start off with a couple of boxes, use the align tools to equally distribute the boxes.

boxes

Add smaller boxes in between the larger boxes.

mergeShape

Use the Merge Shapes option to combine all of the boxes into a single shape.

live-corners

Inside of Illustrator, use the live corners feature to curve the end of the arm shape.

cut-in-half-scissors

Find the middle of the shape and slice the arm in half by using the scissors tool.

revolve

Import the paths into your favorite 3d modeling program and adjust the anchor points for revolving our shape.

revolve options

Revolve the arm shape using quad polygons.

nonlinear-bend

Apply a non-linear bend deformer to the arm. If the width is not narrow or wide, adjust the anchor point closer or farther from the center.

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.
