MJ Coaster Holder

Coaster Holder that holds Six 100mm by 4mm round coasters that have cork backings. Decided to add the MaryJane cutouts and allow for small tree supports. I was able to remove the supports without any issues, but I haven't tried it without supports. This is my first design since I got my A1 so any suggestions for improvement are welcomed as long as they are constructive. Thanks and happy printing.
