Think its possible to make a ring engine that works?

That is one nice acetone bath result, I thought that you used a SLA printer at first. Really nice work. Greetings

Wow very nice! how did you get it so shiny??

I used this technique (only works with ABS): https://www.youtube.com/watch?v=5sblh0bBHoQ
Instead of using a rice cooker, I used an aluminum loaf pan, and put it on the heated bed of my printer. I refrigerated the part before doing this, that way the acetone would condense on the part after it vaporized from the bottom of the pan. I covered the pan with aluminum foil, waited about two minutes (plenty long enough for the acetone to evaporate) and then turned off the heated bed and uncovered the pan, and let it sit to cool for about an hour. That's all there is to it.
