Hi all.
After seeing what @soonercruiser had to go through to get proper backup light bulb holders for his chrome housings I thought I would see what I could come up with.
First take (yes I know the tabs are backwards already fixed)
After a couple hours if cad and 3 hours of printing
Bench test of the plastic prototype
Not a proper test as I do not have the lense and gasket. So too much heat leakage.
3 minutes I could smell plastic heating
10 minutes browning of the plastic above the bulb
15 minutes I'm either nose blind or the smell has subsided
20 minutes I ended the test
But it did not catch on fire!
The black lines are ink from a pen I was using to test how soft the plastic got.
It got soft but did not deform.
Hottest temp I saw was 350 deg F
I'm going to make the small tapered end a bit wider and move the walls of the holder out away from the bulb.
My intention is to print this in metal (AL or stainless)
I'll post more results as I get them.
