Oxygen Tank Wrench

pinshape

I needed an oxygen tank wrench that was convenient enough to clip to my wheelchair for easy access when quick changes of oxygen tanks were needed. A regular adjustable wrench from any hardware store used to be cumbersome and would always smack the metal on my wheelchair, making a loud clanking sound while driving around. This is an Oxygen Tank Wrench designed to fit an oxygen tank used for medical reasons, fitting steel tank valves on top of each tank that must be turned to open and allow oxygen to flow to the recipient. It can also be used for oxygen tanks or other similar tanks for glass blowing, or other uses not just limited to medical reasons. A designated hoop is attached on one end for a key chain ring to hang off of whatever you want. I attached it to a retractable ID key chain so I always know where it is. Print Settings: Rafts: No Supports: No Infill: 50% Notes: This Oxygen Tank Wrench goes under lots of torque pressure from the steel valve when being turned, making a higher infill percentage recommended. I did 25% and it works fine, but after about 25 or 50 uses, the plastic gets indented. To get a reliable Oxygen Tank Wrench, making it more solid in case of emergencies is suggested. Steps Taken To Design: This design was created in Tinkercad and then refined in 123D Design to help make straight edges round for an easy slip onto the valves.
