Stackable Heart Coasters

These are stackable heart coasters with exposed infill created by a couple slicer modifier blocks. Project profiles with these modifier blocks are included for PrusaSlicer and Cura, enabling easy print setup. They are setup for a printer with origin at centre, so you may have to move the objects if your printer has the origin at bottom left, for example.


**LOAD ONE of the 3MF project files, NOT the example gyroid infill model or the solid heart model. They're included for viewing only.** If you use a different slicer, you will have to load the solid heart STL model and add your own modifier blocks.

These look just fine printed in a single color, but if you want, you can change the filament after the bottom layers are printed to get two-color prints like in the images.

The lower modifier block controls the infill pattern and density with zero top layers. The upper block creates the cavity with zero infill, zero bottom layers, and zero top layers. Both blocks should be configured w
