Half Inch Schedule 40 PVC plug

Needed a plug to cover the opening of a ½" schedule 40 pvc pipe so that I can fill the rest of the project with sand. There were not plugs available for my need, and quickly whipped this up on tinker CAD. I made the cylinder hallow to save on unnecessary filament use and the plug rim was thin as i did not need a thick rim for my intended purpose which was to plug the pvc pipe while also allowing the pipe to fit into the other fittings. If plug is loose in the fitting can place painters tape around the plug to make it more snug.
