Propane Tank Regulator Collar Wrench for Weber Grill

Sometimes I find it hard to grip the collar around the propane tank. I wasn't able to find one for a standard Weber regulator. This is only 10mm thick which allow it to slide in between the regulator and the collar. It is just long enough to give a little extra grip. 

Best results are with 6mm walls, top and bottom using Gyroid infill at 25%. Although any filament will work, the best results are with stiff and hard filaments such as PC or ABS.  The photo I showed was PC. 

This will likely work for other regulator hoses not just Weber but it was only tested on a Weber.
