I took the original dispenser made by mkelly and made it a bit larger it to fit the common box sizes we use at a fire department. The dimensions of the item (OD) are now 136.52mm wide x 95.25mm deep x 170mm tall. (5.37in x 3.75in x 7.05in). This size seems to fit most standard size exam glove boxes. (If it is too snug for your liking, expand by about 2% and it will give you the looser feel many commercial dispensers have.)
Easy print - most default settings worked fine for me, took about 9.5 hours, but print speed could probably be increased without much difficulty.
