I was trying to mount some large illuminated arcade buttons on small enclosures and had a hard time reaching the collars to tighten them down. This is a simple tool to reach the collar in tight spaces.
These panel mount buttons are sold under various brand names such as Uxcell. Some examples:
STEP file is included in case you want to edit or extend the tool.
DXF of the mounting hole pattern for these buttons is included in case you want to add one to a project without measuring.
The author marked this model as their own original creation.
