*FIXED* Air engine throttle
thingiverse
This is an Air Throttle for Air engines. the hose fittings are for hoses with ID 4MM and OD 6MM. NOTE. the arm is pretty rough and unfinished but it should get the job done. I included the hose fitting in case you want to run a different hose size so you can remix it and change the size. or you can do the math and scale the hose fitting in Cura. The top O Ring is OD 9MM and ID 6MM. The middle O ring is OD 11MM and ID 8mm. Both o rings Have a cross section of 1.7MM. All the bolts and nuts are 2MM. I used 0.5MM Rubber sheeting between each section for a good seal. DO NOT over tighten the bolts or the PLA will crack or you will strip it out. Try to print it with the least possible amount of support. you do have to use support on some parts. The part support was used on clean them up so everything runs smooth.
