Amazon T8 tombstone modification

This is a remix from https://www.thingiverse.com/thing:398515

Thank you for this idea. You can build T8 compact florescent fixtures DIY for 1/10 the price of a prebuilt fixture for LEDS since you have to buy an entire fixture and remove the ballast. so basically you are buying the 4 tombstones and a metal housing for 20$ when you can get the tombstones for less than 1$ each and thats all you need to build a LED fixture.
The t8 tombstones i bought from amazon were slightly different than the ones the OP must have. So modified to fit these.

Recess deeper and larger
the cutout fits the angled part and 3 tabs better.
Made a double t8 version.
Print settings as rough as you want. i used .6 nozzle 20% infill and .2 layer to spit these out as fast as possible.
I printed without supports. yes the bottom overhang will sag slightly. its is accounted for in the fitment. if something does not show and you cant see
