This is my first contribution of my own design to Thingiverse! I designed it in Rhino and printed it on my TOM. I left a lot of space in the piston cavity and it could probably be tweaked but it works great! Makes a good demo for children or if your bored give it a whirl! Big thanks to my friends at Makerbot support, Matt made this possible!


I printed it in two sizes, one at 100% and the other at 75%, that is the one pictured; It turned out way better than the larger one. I'd like to see one super small if you can pull it off!
Pretty straight forward assembly
.Print the tray,
The dog bone has a smaller end for the piston and the bigger one goes on the flywheel shaft.
It prints well but requires a little bit of alteration to the holes to get them to fit just right.
I was able to assemble it glue free!

Had no problems assembling it, although i find that the piston have too much space between the cylinder and the piston it self.

Yay canada! (The dime in the picture) Going to print when I get home!

I cant get the pieces to fit :(
0.2 mm res
yes raft
replicator mini

Scaled it up to the max size my thing o matic could print. Added some hot glue to stop the piston from coming off and it ROCKS!!!

(See it in the Made section)

Bussy printing this ! 0.3 layer, looks nice!

I managed to printthis at 50% with out any problems. but did have to clean it up a bit with a knife

Great stuff thanks 8-)

How do you reprint certain parts? I tried printing raftlessly, but one of the pins and the piston failed and lost their grip on the platform.

Hang in there, I am reworking this file to be consistent with my other motors. It should be up this weekend.

Excellent work! Sadly the pin for the dog bone and head broke during my print, but a piece of tubing works fine as a replacement.

thank you! Nice thinking with the tube. If you scale it down you could use a hunk of filament instead.

I wouldn't call this print a "Piston Assembly". It is a piston, cylinder, connecting rod and flywheel thus I would call it a "single cylinder engine".

Nice print btw!

sounds good to me!

This is cool, printing now.

Awesome! Let me know how it turns out!
