Description

KeyRing of a combustion V45/V60/V90/V180-engine with turning crankshaft and moving pistons.
Release 2.0 d.d. 28-8-2025: improved clicking of crank cheek/crank case.

Printing
No supports.
I printed with PLA+, layer height 0.15 mm.

Assembly
No glue.
Use some oil or grease between moving parts for a smooth operation.
- Place the piston rods on the crankpin (upper piston rod upside down).
- Screw the pivoting knob on the crankpin.
- Place the pistons with the piston pins on the piston rods.
- Click the pistons in the cylinders, and at the same time click the crankshaft in the crankcase.

Operation
Put your finger on the pivoting knob to turn the crankshaft.

This design is a spin-off of my “Engine KeyRing”.

I really like this design. Only one thing that could be improved is the end of the piston shafts. They are so thin right between the inlet/outlet hole that one was broken during the printing. But this is a minor detail. Thanks for sharing your design.

@Bootjevaarder

Thanks for your comment. I am not quite sure what you mean by the thin end of the piston shaft between the inlet/outlet. Would you be so kind to point out what you mean? Just curious.

@Enginseer.Prime

Replying to @Bootjevaarder :

Sure.

@Bootjevaarder

Replying to @Enginseer.Prime :

I see what you mean. I think your problem is caused by using the Print Profile of Trusted Developments: 0.20 mm layer height instead of the recommended 0.15 mm. Small difference, small problem.

@imthehenroy123

any suggestions on how to Fix this

@user_3253596676

Yes, you have to download the correct file for your printer, then select the filaments you actually have instead of the ones the maker has set, then it should work

is okay - timings don't fit at all Quite unstable nevertheless 4 out of 5 stars as print quality is okay Tolerances could be tighter thanks

Works great with PLA, but PETG did not work as well
