This is a Yeti lid magslider with the Texas Longhorn logo on top. It is for the 20oz and 30oz tumbler lid. when slicing, add a pause at 3.08mm so a 6mm x 2mm round magnet can be inserted. test the polarity of the magnet on the cup lid before inserting it to insure proper operation. I used the “Magnetic Yeti Slider Lid - Smooth” model from thingiverse by @Shynd, and added the Longhorn Logo on top.
The author remixed this model.
I kept it the same and just added the Longhorn logo on top.
