Tired of not fitting your coffee mug in that fancy cup holder in your TV or movie couch? This model will fit into any existing cup holder, and provides an easy way to keep your coffee or evening tea stable while enjoying a movie.
There are a few pre-defined sets here, but some of th emodeals can be scaled (see below). I do like the threaded version though, which gives a lot of range for the depth of the cup holder without scaling.
The example gcode was done for speed, and using a 0.6mm nozzle. You should not need support for any of these files. Layer height can be 0.20mm or whatever you prefer, the example uses 0.36mm layer height for the bottom portion, and switches to 0.20mm when the rounded top pieces are starting (around 68mm layer).
Infill does not need to be high, I printed at 10% infill using Adaptive Cubic (my favorite). For extra strength, instead add an extra peripheral if needed (I used 1.2mm peripheral).
I've removed the old models, and now only support the new versions, which have taller, notched walls for the handle of a cup. The design comes in four versions:
The hollow versions should work for any printer, without supports, including resin printers. All models have a base diameter of 90mm, and a cup depth of 60mm. Use these when calculating the scaling you have to do to fit your chairs.
My couch had a 80mm diameter cup holder, with a 66mm depth (both padded)
Remember to pad your measurements properly, you don't want a super snug fit here, or it will never come out of the cup holder. I'd pad at least 2-3mm in each direction.
From suggestions and discussions on the forums here, I've added a threaded version, well 3 of them, which makes it easier to adjust the depth without changing the scale. This prints in two parts, “top” and “bottom”. There are three variations, 80mm, 85mm and 90mm diameter, and probably can be scaled somewhat.
The threads should be a good fit, I tried several prints to get them tight, but not too tight. If anyone experiences problems.
I think the 90mm diameter is generally good, but I'm contemplating making either a second set of cups with a 65mm cup depth. Or, make 65mm the default; I've so far done 3 different cup insets, measuring from 63mm to 66mm, so 65mm may be the better default on the depth.
