This is a sliding valve air/steam engine. It was inspired by https://www.thingiverse.com/thing:34701 and built off of my Wobbler 2.0 components.
This engine uses 2 608ZZ Bearings. There is a detailed bill of materials in the engine.pdf file.
25 JAN 18 - Update: Added orientation picture. To my best recollection this is how i oriented the parts for printing. Note: I did not print them all in one shot like shown....
27 AUG 17 - Update: Slider_3 works very well. Achieved 2700 RPM.
26 AUG 17 - Update: Per a comment from +Holzmichel two other sliders have been added. Both of these are experimental as I have not tried them yet. However I believe they will increase performance. .step files are included if you would like to modify.
UPDATE: Added crank_asm.pdf to help clarify assembly of the eccentric.
The engine in action.

I've attached a .step file of the assembly if you would like to remix or improve.
Please let me know if you have questions, suggestions or parts need fixed.
Thanks!
