Furnace door knob

The design on the access door latch/knob on my carrier furnace was a VERY poor design. They break all the time. You can buy replacement parts sure, buy they will continue to break.
This is much stronger and should solve all the issues I had with it.
I used a 5/16 x 2 1/2 bolt to connect the two pieces together.

I printed with 50% infill for strength
