A simple coffee mug coaster for mugs with a diameter up to 85mm and a coin holder for your daily coffee at the office.

The middle part is just a circle with hexagon infill and no top/bottom layers. If you want to add a custom logo to the middle part as shown in one of my pictures, you can do so by following these steps:

1. Open the 3mf in Bambu Studio as usual
2. load your custom model and place it inside the “infill” part. If you need to resize it, make sure that the height is at 2mm
3. under “Objects” tab, select the Assembly and your logo by holding strg, then right click at “Assembe”
4. right click your logo, change Type to Modifyer
5. under “Objects” select you logo and go to “Strength”, now just change the wall loops to 0
6. now when you slice again, you will see your logo.

Sometimes there seems to be a bug where the logo looks not visible, has no walls or top/ bottom layers. If so, select the logo (modifyer) and change the wall loops to 1 and then back to 0. Do the same with the top/bottom layers. Change them to 5 and back to 4.

Seems that Bambu studio sometimes don't use the settings but by selecting them again, it works.

I uploaded a youtube video to show the whole process.
