Compressed air engine with flywheel WORKING model 3D print model

this is the first prototype of my compressed air engine. it doenst run super efficiently, however it is a good project to work on if you can spend more than a few days on one task. There is a little bit of tinkering to get it to work, however it is super cool once it does!I printed all of the parts at 30% infil and only used supports for the flywheel and the crankcase (print the crankcase upside down with 15% support)you will need to purchase 1/4-20 bolts and nuts.

• 2 bolts, 2 in long
• 2 bolts, 1.5 in long
• 4 bolts, 1 in long
• 8 nuts, 1/4 20 thread
