No-holes fire extinguisher mounting bracket
I wanted to mount my halon fire extinguisher in my car, but didn't want to drill any holes. It's large enough that the only practical place to put it is in the back seat floor board. I ended up making brackets with my 3D printer that worked great. I thought I would share this with the forum and offer them for sale.
These brackets are designed for 1968 - 1972 A-body cars, but may fit other models as well. The brackets are made from a material called PETG, which is used to make 2 liter pop bottles. The PETG that I use for these brackets is also infused with carbon fiber. They are very light but very strong and are more than adequate to hold up to a 2.5 pound fire extinguisher, which is what I have. The only drawback is that PETG starts to melt around 175 degrees F, so if you live in a climate where your car sees those kind of temps in the interior, this may not work.
Here is what the bracket looks like, with the fire extinguisher bracket mounted to it:

The upper bracket is made to slip inside the rear seat mounting bracket. A bolt runs thru the seat bracket and fire extinguisher bracket to hold it in place. No drilling!

I have made a bracket that is somewhat universal and should fit various fire extinguisher brackets. Here are the measurements of the holes. The rectangular mounting portion of the bracket measures 165 mm x 36 mm. You would need to drill the two lower outside holes, if desired:

I have also made a blank bracket, for which you will need to drill your own mounting holes:

The width of the upper bracket (the one that fits within the seat mounting bracket) is 11 mm. The seat bracket it's designed for looks like this:

I'm selling the bracket kit, which includes two 3D printed brackets, for $20 shipped within the US. If you wish to buy one, please PM me. Please measure your fire extinguisher bracket and make sure it fits, or order the blank bracket.
