Swifty - Mini FDM Printer

thingiverse

This mini printer is built around Swiffer sticks. I call it Swifty. The body frame is made from a Swiffer stick and other printed parts. At first, I tried to use old stepper motors, smooth rods, desktop switches, bearings, and timing belts from recycled printers. However, there were quality issues, so I decided to purchase specialized CNC machine parts instead. Build size: 100x120x80 (xyz) To build Swifty, you will need: Two Swiffer sticks as the frame of the machine. These sticks are sturdy and easy to handle. 1. Nema 17 stepper motor: 5 units, $35 2. Arduino Mega 2560, Ramps 1.4 + 5 stepper motor drivers, screen: $35 3. E3D V6 nozzle set: $5 4. 15cm Lead screw and brass nut: 2 units, $5 (20cm Lead screw recommended for builds over 130mm height) 5. 8mm 20cm smooth rod: 4 units, $13 6. 6mm 18cm smooth rod: 2 units, $6 (25cm rod recommended for builds over 130mm height) 7.
