I liked the original Pasta Machine for Playdough by edelsteff a lot but ran into the problem where, sometimes when the play dough gets really old and tough, the crank would spin free, meaning the self-tapped thread inside the roller had been compromised.

I therefore created a triangular connection which makes it impossible for roller and crank to spin independently from each other. I also slightly increased the depth of the crank‘s “spacer” through the pasta machine wall. This enables you to glue both parts together without the need for a screw. Remember to first put the wall inbetween though :-)

The crank‘s screw hole is 17 mm, so pick an M3 screw of ~22-25 mm to connect crank and roller. Other than that I went with 16 mm M3 screws for the whole assembly.

Print settings:

• 0,2 mm layer height
• 3 perimeters/top/bottom
• 15% gyroid infill

For the snap-fit handle I recommend something other than common PLA. I printed in SUNLU black PLA+, which turned out quite forgiving and has yet to break. A regular SUNLU PLA snap-fit handle didn't even last a single assembly! Therefore choose something with a little bit of give.

I‘d appreciate a “like” if you do and look forward to your makes <3 also please share your feedback on the design!
 

Thanks to the original author for the model!
