Espresso Cup Shelf (2 1/2" x 2 1/2" Max Cup Size)

This small shelf is designed to fit inside a cabinet and hold up to nine espresso cups with a maximum size of 2 1/2" high by 2 1/2" diameter/width each. The handles can be oriented to stick out as shown in the image, so you usually do not need to include the handle dimension when you measure your cups. This shelf works great for the mini Starbucks espresso cups and may work well for others.This model is best printed with the shelf laying down on its back. It fills most of the print bed and sometimes the corners may lift during the print. The back of the shelf is not often seen, but to help with preventing the lifting corners I have found that increasing the heat of the print bed 15C hotter for the first layer may improve adhesion and keep the corners down. For example, for PLA, use 65C for the first layer and 50C for the rest of the print.Since the entire model is essentially all thin walls there is no need for infill.
