This is an assembly of the Prusa Mendel RepRap, Iteration 2.

I'm using the variation with slightly longer X axis smooth rods (412mm) and an extra 4 nuts and 4 washers on the top (allowing the z-motor-mounts to be adjustable). Blue rods are threaded rods.

I lined these all up by hand, using OpenSCAD in Orthagonal mode to verify each aligned hole, etc.

The real work of this thing is the file assembled_JLK.scad. In the same directory as this file, place the the contents of the directory "metric-prusa-lm8uu" from inside https://github.com/prusajr/PrusaMendel.git (which I included in this thing).

I also used the Buddaschnozzle model from here:

Note: As an exercise, I did this using only the actual STL files, not the OpenSCAD source for the parts that generate those STLs.

Marking as a work in progress because there are more things to add that I just haven't gotten around to.

EDIT: Saw that the location of the bar clamps on the bottom of the triangles was off for some reason, fixed it with _v2 and removed original.


Open up the file assembled_JLK_v2.scad (with all of the other attached files in the same directory).

This was made to show how parts are supposed to line up, things like the Y-axis bars being on top, etc.

Hey whats the official distance between the X rails?

Hello, i wanto to know how to open this files in solidwork, because i just want to see the asembled model in solidwork.

I have found a different model, you do not need any more converting.

"assembled_JLK_v2.scad" works not with OpenSCAD version 2014.03.
I have the file loaded, press F6 and then:

i cant wxport this...

i you upload the assembled_JLK_v2 as stl-File?

i can't even tell you much much i can't wait to try this in my summer break

Having this model was SOOOOO helpful when I built my Prusa IT2...You almost just need this.
