1 1/4 - 11 1/2 NPTF Cap

I wouldn't recommend using it on a pressurized line. I made this cap to cover up a water line. The cap threads on nicely but we turned the water on just to check and it blew off when pressurized. It will work fine for us because we have the water shut off at our end. This cap is a standard 1 1/4 - 11 1/2 NPTF female threaded piece, meant for non-pressurized situations only. I wanted to avoid wasting filament so I printed it open side up without using any supports. If you take a close look at one of the pictures you can see how stringy and fragile the bridging material was initially, but after completing the print process, everything works out perfectly. Print Settings: Rafts: Doesn't matter what raft option you use in Cura Supports: Use any kind or amount of supports as it will be a waste Notes: Print speed at 75 mm/s Using a standard PLA filament that reaches its temperature optimum of 210º At room temperature the filament's best operating setting is to be at about 65º
