Mi Mix 3/5G pla/tpu case

I designed a new version for the Mi Mix 3 case. It was not bad, but fit was not perfect and even with the support the final quality was very improvable. This version may be harder to print and include more steps, but the final result is better in overall quality, fitness and aesthetic.

To print the complete case you need to print first 2 pla pieces that will be inserted mid print. One is a hexagon part that improves aesthetic and makes the case a little more hard. For this part I used wood pla but anything should work. The other part is a frame that will be inserted just before the final part. This will act as a support for the overhangs and also make the case fit better. I used white pla for this one.

Tips for the pla pieces:

The hexagon one should be clean without imperfections to fit in the hole mid-print. Otherwise the parts where it is not fully inserted will come worse, as you can see in some parts of my print.

The frame/support part has 6 aligners that will be inserted onto the respective holes to help the piece be perfectly positioned. Don't worry if the top part of the aligners doesn't print well, you can cut half of the height of the aligners and they will still be functional. Just make sure to insert all of them before continuing the print.

General printing tips:

I used 0.15mm resolution for all pieces. Remember to add pauses on the tpu part to insert the pla parts. It should be on the top part of the hexagon pattern (just before it's covered), and on the top part of the insert holes (the ones where the aligner pieces go).

Some pieces have face errors. I should probably fix that, but it works like that and I'm not a 3d expert, so I just fixed what I needed to make it slice and print right.
