Lót Ly Stargate (Stargate Coaster)

Material

I printed this in PET-G, which is not suitable for very hot drinks.

The middle part, where the hot mug would stand on, is a separate part. So it can be printed in different material, such as ASA or PC blend. In Prusa Slicer:

Option 1

Print top separately, then insert it into the model

1. Print Stargate Coaster - Negative Volume

2. Print Cylinder Top in a different material

3. Assemble

Option 2

Print directly from two materials. I haven't tried this and slicer will complain but you can give it a shot.

1. Find part named Cylinder Top

2. Assign material to one with better temperature resistance

3. Print all, no assembly needed

Option 3

Make the middle part out of a cork coaster.

1. Find a square/round cork coaster that is at least 80 mm wide

2. Measure the thickness of the coaster

3. Calculate the Cylinder Bottom height: 4.9mm - Coaster thickness.
   For example for a 2 mm coaster, the thickness would be 2.9. If not sure, choose a higher value (it's better if the cork sticks out a little bit).

4. Open Stargate Coaster.3mf

5. Find part named Cylinder Top and delete it.

6. Find part named Cylinder Bottom and change it's height to the calculated value.

7. Print the model

8. Optionally print Cylinder Top as a template to cut the cork

9. Cut the cork to shape with a sharp knife

10. Assemble
