We found latest Prusa i3 printer design, the one Josef Prusa showed at Makerfaire this year in New York, for its elegant simplicity, but hinge like connection between Y axis assembly and frame needed improvement, in our opinion.
Using CAD software we reworked Prusa i3 design:
- Laser cut frame was stiffen by adding two angle members connected to the rear side of Y axis assembly.
- Original, printed Z Axis mounting parts proven to be easy to break, which is why we replaced them with stronger laser cut parts.
- We did not like loose ends on Z Axis lead screw (similar to Printrbot design), therefore we added miniature flanged ball bearing on each side, to support lead screws on the top.
- All printed plastic parts were slightly changed, we felt that we should give them additional strength and better cosmetic appearance.
- Y axis assembly can be removed and installed back in a minute. Convenient for transportation or shipment.
- Dimensions and axis travels of original Prusa i3 preserved.
