Cup Holder with Mounting Holes

cults3d

Requires a vertical mounting surface at least 13cm (about 5") wide. I installed my cup holders on an old beat up couch and comfy chair because it's no problem getting holes in the exterior of the furniture. My roommate is using an ABS print of this design on his portable work bench. Print the base and the cup separately. Shouldn't be necessary to use supports, however for the large base a heated bed will be very helpful to prevent warping, even with PLA. For PLA, 60degC seems to work well; for ABS, 105degC is great. Once the cup and base are both printed, superglue them together with the triangular base pointing up, i.e. the narrow side of the base is on the same side as the open rim of the cup. Then when the glue has set the entire assembly can be mounted on a vertical piece of wood or plastic with self-tapping screws.
