I like designing coasters as they are usually pretty easy and obviously super useful.  Being into Star Wars, I decided to design some simple coasters and then decided that I needed a coaster holder…because why not?  The Millenium Falcon was the first thing that came to my mind.  After a few renditions, I came up with this model that uses magnets to keep the top on.  The magnets I used were NEXLEVL super mini fridge magnets…¼" by 1/16" round.  It is designed to hold 4 coasters.  When it comes to printing, any layer height works; however, I printed mine at .1mm as well as .2mm.  I also like to use two colors during the print to add more character.  This can also be printed without supports.  I will be doing more coasters here down the road, so check back!
