Bi-fold closet pivot cap

thingiverse

Human: (n.b., this did not fit my closet pivot due to my misjudging some dimensions and not realizing there was a flared lip on the pivot, hidden by the broken plastic piece over it; I didn't remove it until I got the new 3D-printed one); the other bifold pivot "thing" is much closer to the intended piece it's replacing, with two different sized holes to allow the bushing to slip over the pivot's flared lip (see image). ========= Plastic cap to replace the broken one on my outdated and no-longer-available top pivot spring-loaded post/guide for a wooden folding door, which is about 30 years old as of 2018; no retailer had a match for it, and no modern pivot/cap fits. The cap takes no weight and is used only to guide the closet door through the top rail/track. The cap is hollow to allow it to be placed over the metal pin, which has an interior lip to prevent the cap from popping out; I couldn't get the old cap off the pin without using a vice and pliers. The cap goes into the rail/track with some wobble room while the brim (bottom) of the cap keeps the hat (cylinder) from wandering out of the rail, while the pin's spring keeps the brim flush on the bottom lip of the rail/track. The hat does not rotate/spin when moved, but there's nothing wrong with it doing so. Measurements: The top of the cap's hollow or inside diameter is 3/8". The top of the hat's outside dia is 1/2" (hat thickness = 1/16"). The hat is 3/8" high, including the 1/16" thick/high brim. The brim's dia across its bottom is 5/8".
