While I was looking at my Nuka-Cola bottle and the bottlecaps it came to my mind that a very (!) large bottlecap would be a nice tray or wall decoration. I upscaled my design by 780% and the print failed miserably… The overhangs at the bottom looked terrible. Lessons-learned, this model cannot be scaled - so I re-designed it.

I made two models, one for the A1 mini with a diameter of 180mm and one for the A1/P1/X1 with a diameter of 250mm. If you have to much filament and need to waste it, just give these prints a try.

Print preparation:
Make sure that your print bed is clean and grease-free. An unsufficient bed adhesion is in most cases not a problem of the print profile but a cleanliness issue. If you want you can use glue on your print bed but for PLA this should not be necessary. If possible use the smooth textured PEI plate and a bed temperature of 60-65°C.
For the print quality it is important that you use a good and calibrated filament. Know your k-factor and use the correct flow setting. Bambu filament makes this step easier but any other quality brand will do the job.

Print settings:
The print settings are pretty much straight forward. Use the 0.2mm standard setting with three walls, 5 tops, 4 bottoms and 12% cubic infill. Support is not needed. If you are printing multi-colour a small prime tower will help to separate the colours.

I made print profiles for A1mini (Ø180mm) and A1/P1/X1 (Ø250mm) with and without AMS.

Assembly:

This is only necessary if you print the single colour versions, then you have to glue the parts together. Simple superglue will do the job. The gap between the parts is 0.2mm so assembly should not be an issue if your filament is calibrated.
