This is a customizable coaster set. I've included the source .prt files (let me know if you need a different format) of templates of the coasters/holder so that the text can be personalized. See the featured image for an example - this version has my family members' names written into the side of each wall of the holder and our family name in center of each coaster.

No supports or raft are needed for print. (I really recommend against using a raft on the coasters; depending on your text size, it could be pretty painful removing the raft from the letters.)
