.375 FNPT Cap fitting

This is a cap for FNPT threads 0.375 sized pipe/fitting. This is a modified design of a brass-based design I used previously, I increased the wall thickness for use with PLA to print in an emergency. NOT safe for long-term use.

Print with 100% infill and 4 or more walls. Ensure your layer adhesion is dialed in for a leak-proof cap
