This is remix of the original k-iced riser plate that is a FANTASTIC design by southbaygsr I just have a Starbucks coffee mug that's too tall for the original file, I didn't even print it after looking at it in my slicer, knew it was about 8mm too tall so I simply removed 10mm without affecting any of the rest of the model.
The author remixed this model.
I removed 10mm (1cm) about 3/8 of an inch from the center of this piece so that my larger mug would fit. I am very new to 3d printing, but I figured out this much and figured it would, well, might, be a help to someone who needs this file 10mm shorter!! : )
