Tiny-M

A compact printer with build volume: 150x150x150 mm

This is a Corona project.
It is based on Voron V0 .
As extruder I used Voron Jetpack. or my new Nema17 Pocketwatch A direct drive extruder using Annex Engineering's Sherpa Mini is now available.

Current Version is V4:

latest source whole printer: Tiny-M V4 Onshape

old source is available at Tiny-M V3 Onshape.

This is my first project of this kind. Maybe something will be missing, is not well documented, or just messy. I apologize for that.

Why the whole thing?

I had many 3D printer parts in my pocket from my old no longer used printer. I cleared out my pocket and took what I had in the box without buying anything new. After checking all parts, I recognize, that I could build a converted Voron V0 with this parts.

Hardware

Build Tips

There are 3 versions of the XY-Joins.

V2 - use 2GT 20T pulleys - No Set Screw Hub
- The outer diameter of the flanges from the pulleys for XY Joins will not fit.
- You will need to grind the flanges to fit.
V3 - use 2GT 20T toothed idler and no M5 Nuts
V4 - split into 3 parts
- removed one M5 screw for better alignment
- optimized belt path to use E3D idler (10mm high) or chinese (9mm high)
- some design changes
- more rigid
