Cartridge Cap Modified to allow differing O rings

Human: Adapted from the original excellent file from "The Sealant Cartridge Nozzle Cap That works" by The-Mechanic. Published on January 23, 2019 https://www.thingiverse.com/thing:3375441 I modified this as the O-ring in the original was not easily available in the UK. The Fusion 360 file lets you adjust the O-ring size in Modify - Change Parameters from the menu bar in Fusion 360; see graphic in file list. The thread is 9/16 UNC to fit cartridges in the UK and probably elsewhere; again, this can be modified in the file. The default of the O-ring is 25mm and 3.2mm. The height can be cut by half, but I prefer the chunkier version with work gloves. Time to print was 38 minutes at 25% infill. I should have put a bevel on the top edge of 1 mm to save cleanup. It's very easy to do in Fusion 360.
