Create an exact-size 3D printable drink coaster with round, rounded-square, or hexagonal geometry, an optional condensation rim, and personalized text, emoji, or SVG artwork.
Design a Custom 3D Printable Coaster
The Custom Coaster Builder makes it easy to create a drink coaster sized for your glassware, mugs, desk setup, or gift project. Choose a round, rounded-square, or hexagonal shape, set the exact outside size and thickness, and preview the result before exporting it for 3D printing.
Customize Your Coaster Dimensions
Use the size control to match the coaster to the cups and glasses you actually use. Adjust base thickness for a lighter everyday print or a more substantial feel. Rounded-square designs also include a corner-radius control so you can tune the profile from crisp to soft.
Add an Optional Condensation Rim
Enable the raised perimeter rim when you want a shallow edge around the coaster. Rim width and height are independently adjustable, making it easy to create anything from a subtle border to a more pronounced edge for light condensation.
Designed for Straightforward 3D Printing
The base geometry is designed to print flat on the build plate without supports in normal configurations. Before printing a full set, export one test coaster and verify dimensions, rim behavior, and slicer manifold checks with your preferred material and printer profile.
Ideas for Custom Coasters
Create matching coasters for a home bar, coffee station, office desk, game room, event table, or handmade gift set. Start with a simple shape and dimensions that fit your use case, then save or share your design using STLPlayground’s supported design tools.
