MicroCube printer

Hi guys,

I'd like to share my latest project built with the Robo3D (and some parts with my delta in parallel). Let me introduce the MicroCube, a small h-bot desktop printer, first designed to use the small 28BYJ-48 stepper motors, but meanwhile also available with Nema17 steppers.

My goal was a cheap, easy to build, small printer. I had only little time, so it took some month to finish, but now I am done, it is so small that it nearly fits into the build space of the Robo3D, what do you think of the MicroCube?

All files are available at Thingiverse (https://www.thingiverse.com/thing:1938877)

 

Without the cable loop, it would have fit completly into the Robo3D

Heated bed would of course be possible, but my Robo3D has one, my Rostock Mini has one, therefor I designed the MicroCube as a PLA only printer without a heatbed.

Total costs were about 100€, I had a lot of parts lying around, the rest was ordered by ebay or Amazon or bought at the local hardware store, here a rough calculation:

Arduino + RAMPs 30€
Aluminium rods 5€
28BYJ-48 stepper 10€
Power supply 12V/10A 10€
Smooth rods 15€
Hotend E3D V6 clone 10€
Linear bearings 10€
Screws, wires, etc. 10€
------------------------------------
Total ~100€

Addons:
LCD smart controller 10€
Nema17 upgrade 25€

 

Very cool! I have an older Printrbot Simple (original wood version) and I've been pondering building a new portable bot for demos. It already used fishing line as its drive belts, so it's like a cousin..

SO much fun seeing other designs, especially easy to build ones..
