I got some 15 gal barrels for kerosene for heat for my house.

needed a wrench for removing the caps. did not want to buy one did not like any that were online so I mixed 2 tools. wolf's wrench (for the bottom part) and someone else made a nice handle I rescaled and merged the files in tinkercad to make this nice simple barrel driver.

I CAN NOT FIND the original handle I used on thingiverse. my download is just the stl so no info file for the source to give remix credit. if anyone can find it (been looking for 30min now) let me know and I will add the remix credit. the file name is Part_Studio1-_Handle.stl

4 perimeters 25% infill should work fine.

I also print 2 perimeters 20% infill .4mm layer height with a 1mm nozzle and those come our really nice.

his tool had an open center so mine does as well but none of my caps need this. SO if yours does not either tell you slicer to "seal" the whole model (gets rid of that hole) stronger faster print if you don't need the hole in the middle.
