This kit is to replace all the part from the original cooler Coleman drain plug. 

I made the design to used the original gasket to prevent leak. 
You can print the gasket in TPU or maybe use a gardenhose gasket.

Personnally, I printed it in PLA+ and I will check if it's holdup, otherwise I will reprint in PETG.

Print settings:

• resolution 0.20 mm
• 4 perimeters
• 30 to 40 infill
• No support

Please like and post photo !!

Thanks :)
