Hack a Coffee Maker into a Delta 3D printer

Tropical Labs team made a coffee maker into a Delta 3d printer. Interesting hack. Tropical Labs engineers have been developing a flexible design for ultra-affordable 3D printers and this a part of their efforts.

Video of the Delta printing:

Printer features:

  • Coffee maker, Tropical Labs used an old Norelco 12 model they found at a thrift shop, but any coffee maker with a hot plate could potentially work 
  • Arduino Mega 2560
  • RAMPS 1.4
  • A4988 Stepper Motor Driver Carrier
  • Nema 17 stepper motors
  • Home switches, optical or otherwise
  • 3D printer hot end/extruder – again, any kind will do; Tropical Labs snagged theirs on eBay
  • 12V power supply
  • Solid state relay (Fotek SSR-40 or similar)
  • Ball joints
  • 4-40 threaded rod

Jebediah the DIY 3D Printable Quadruped Robot

TogleFritz developed a futuristic four legged robot you can make with some basic 3d printing and electronics skills. 

Project description:
Jeb is a quadruped robot that the code in this repository is designed to control. Quadruped robots are robots with four legs. Jeb is designed with three degrees of freedom per leg. Each leg is actuated by three servos. The first servo moves the leg forward/backward, the second servo moves the leg up and down, and the third servo bends the leg in the middle. With four legs and three servos per leg, the robot is driven by 12 servos in total.

Jebediah looks cool (in an insectoid kinda way):

Detailed build guide;


GitHub repository of the project with all the files and other information:


Code is at:


  • The microcontroller used is a Botboarduino
  • The servo controller is an SSC-32U
  • For input the robot uses a wireless Platstation 2
  • This repository also includes a library for using NeoPixel LED lighting products from Adafruit.
