When printing this model, please do only use temperature stable filaments that can withstand the highest temperatures of your used dishwasher. For me this started at ASA.
That and ABS could also be vapor smoothed after printing, to seal the surface area of the printed parts.
This tray was specifically designed to be used with cups that have a bottom diameter of 19mm, and upper diameter of 32mm and a height of 34mm.
The tolerances on this print are by design very tight, so that the contraption does not come apart in use.
The author marked this model as their own original creation.
