Great design. you made it man! Thx.

Hey Andrew, looks like a great build. I'd like to use it for my prusa, but it has a 6mm thick plane to hold on. I changed it in the scad file but when I export to STL it only exports 1 file.

Hi Dries,
I am not sure what you mean exactly. What variant of Prusa i3 are you building?

I also have the Prusa i3 (a la P3steel), but my frame (which this slides on to) is thicker than the P3steel, it is 6mm thick. I changed that parameter in the scad to 6mm, but when I compile and export, it only exports 1 of the modules, not all of them.

Ok, now I get it, sorry! Take a look at the very end of the OpenSCAD file and you'll notice that only one module call is uncommented, this is done so that each part gets generated separately, but from the same OpenSCAD file. Just uncomment one module call at a time and generate the STLs that you need/want (I believe in your case you only need to change the P3Steel_horiz part).
I have adopted the convention to have always first the parameters, then the modules, and finally the module calls in all my OpenSCAD files.

Hi Matt,
Thanks for the elegantly simple and functional original design! It's been rock solid up until now and it's definitely the best (imnsho) Y endstop for the very specific requirements of the P3Steel.
It's one of those install, adjust and forget parts. So much so that I am using the same parts for both my P3Steel printers and also for my under construction Prusa i3 Twelvepro.

Nice... how is it working for you? I was worried about the vertical bar flexing as the bed pressed against the endstop, but I haven't seen an issue with it. Seems stable overall.
