Wrench for Oil Filter Oventrop, Tigerloop, etc.

thingiverse

This is a tool for a very common oil filter used in many heating systems. Normally, you can open and close it without any tools. However, sometimes it's extremely difficult to open, especially if the filter has been changed a long time ago. Also, this tool is very convenient for closing. The thread of the screw is extremely fine. To avoid mistakes, the nut must be held exactly even. You can place the nut in the tool. Thanks to its design, the nut cannot fall through! The tool also helps hold the nut steady when closing. If you want it stronger than necessary, you can scale the z-dimension or change the infill settings.
