Hi,
is it possible to get the CAD files from the extruder ?
I need it for my CAD-drawing for my own 3D printer.

best regarts

Chris

I would also like to receive cad files as true open source products for the use of the community. Sharing is caring.

Hello,

i would also be interested in 3D data of the Bulldog XL extruder. So that I could construct the needed support for my RepRap printer. Thanks in advance for the data. Please if possible in the STEP format.

regards
Matthias

Did anyone ever get the design files?

RRD promotes this is an open source project but I cant find any files, not even in their open source section on their site.

No, they didnt, not as far as i can see, unless they all had NDA...

Im currently making my own version of this as could not find desing files.

I've looked many times, can not find anything. As far as I know my files on Thingiverse are the only reference, they are drawn to size if you wanted to reference those. I will eventually get to the groovehead mount if I can find it again...
