Hugo
Release status: working
This is Hugo. Named after Hugo de Vries who introduced the term "mutation".
The entire design is done in OpenSCAD and all files are hosted on https://github.com/kr2/Hugo.
It is a derivative of the original Printrbot by abdrumm, but all parts are redesigned and improved.
Some Improvements are:
- Nut traps everywhere
- Optional cross braces
- Centered y belt
- Carriage with 3 bearings
- Belt tensioner for x and y Belts
- Additional support in y direction

Instructions
There is a H-Assembly.scad, which is not perfect but shows a complete setup of the printer. To view this H-Assembly.scad I recommend to use the actual developer release of OpenScad e.g. [3] and to set the value for "Turn off render at ... elements" [edit->Preferences] to a higher value (I use 200000).
This WILL need good hardware acceleration to view in openSCAD, ensure you have a modern graphics card and if your in Linux ensure you have your graphics card drivers working - Thebaron88 18:49, 14 May 2012 (UTC)
There are several prebuilt .stl files to discover and to put your own assembly together or you build your own via OpenSCAD.
In general if you print H-Set1.stl and H-Set2.stl you should have all mandatory parts to build the printer. If you also print H-Set3.stl you should be able to setup the entire printer with reinforcements as shown in H-Assembly.scad. The H-Set7_PLA.stl contains all necessary linear bearings plus some extra, in case some come out in bad quality. This bearings should be printed in PLA because it is harder then ABS.
Print the H-TestObject.stl first to check the quality of your prints. It has the main difficulties of the printed objects in one part.
