A very simple model which you super glue to the bottom of a tile or anything else that is fairly heat resistant to lift your coaster off of the table. It is recommended that you only use three because the heights of them may vary between each one leading to it rocking back and forth depending on where the weight is situated on them if you have four of them.
The main reason I did not want to 3D model an entire coaster is because I intended to print it out of PLA and putting a hot drink on a coaster made out of pla may cause it to warp and melt.
The author marked this model as their own original creation.
