Sunbeam sphegnonamometer bulb

The original one I had was broken and crumbling, so I made this. I believe this one is taller, but the fit for the check valve and hose barb is great! the check valve takes a little bit of pressure to get in but works great. i added a stop for the check ball into this print because the tabs to hold the ball broke off. the addition seems to make it work again. and is compatible with non broken ones also. the pumping action and hand fit seems to be really good, durability seems excellent also.

I kept having issues with the print getting too hot and distorting, so be careful with that, you may want to put the check ball side downward and put a tiny support in that hole. it seems that the unit is printable without external or internal supports except for that checkball part. watch the area of the bulb just inward of the ends for distortion, that's where it kept happening for me.
