Round and Square Coaster Holders

As you maybe aware i tend to spend my time creating designs for drinks coasters, you can see many of my designs in my profile here on makeronline. I wanted to create a set of coaster holders to allow people to store the coasters, the holders hold 4 x square 100mm x 100mm coasters with a thickness of 2.5mm 4 x round 100mm x 100mm coasters with a thickness of 2.5mm You can adjust the size using scaling to suit any coasters you may already have. I have also included a set of 4 3D printer themed square coasters and 4 Name themed round coasters to demonstrate how the holders work.
