Oxygen Tank Wrench

thingiverse

I required an oxygen tank wrench that was convenient enough to clip to my wheelchair for easy access when quick changes of oxygen tanks were necessary. In need of a new wrench, I used to carry a regular adjustable wrench from any hardware store but that was too much hassle and would always smack the metal on my wheelchair and make a loud clanking sound while driving around. This Oxygen Tank Wrench is 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 for medical reasons. It has a designated hoop on one end for a keychain ring to hang off of whatever I want. I attached it to a retractable ID keychain so I always know where it is. Print Settings Printer: Flashforge Dreamer Rafts: No Supports: No Infill: 50% Notes: This Oxygen Tank Wrench goes under lots of torque pressure from the steel valve when being turned. I suggest making the infill 50% or more. I did 25% and it works good, but you can tell that after about 25 or 50 uses that the plastic is getting indented. So to get a reliable Oxygen Tank Wrench, I suggest making it more solid in case of emergencies. How I Designed This Steps Taken To Design I designed this in Tinkercad then brought it into 123D Design to refine the straight edges and make them a little round for an easy slip onto the valves.
