Summary

This is a modified version of Bill Dube's Design, which I wish I had before I drilled the mounting panels on my EV Conversion (1968 el Camino).

The purpose is to be able to mount a fast-acting 2" diameter fuse directly to a Gigavac-style contactor instead of using standoffs and a copper bus bar.

Some of the key changes from Bill's design are:

Round zip-tie hole is now square/flat, and designed to come up to the arc of the fuse body as a tangent in order to increase strength of hold and reduce bending on the zip-tie.
All variations of my design include either an option for a hex bolt to be used to hold down through the mount. Two variations allow the use of a non-nylon nut that would have to be imbedded into the print. Otherwise, the bolt would feed upwards through the mount with about .3" of clearance.
I filleted the corners of the mounting tabs instead of chamfering so that there were no interior corners that could contribute to stress failure.
I also included variations for four mounting holes instead of just two. Just in case you felt like two was not enough.

All versions would require a solid build with ABS or PETG, possibly fiberglass reinforcement.
