Coming from a Hydro Flask with the extra Sleeve/Boot i created my own quick and dirty sleeve for the 21oz bottle.

It offers a little extra protection, nice contrast and dampen the sound of placing it on a hard surface.

I also added a little venting hole for easier time putting and taking it off and to let moisture out.

It got a tight but not too tight fit, it just works.

Printed on a BambuLab P1P using these overall settings:

• Filament: Overture 95A TPU in Black
• Nozzle: 0.4mm
• Layer Height: 0.20mm
• Wall Loops: 2
• Top Shell Layers: 4
• Bottom Shell Layers: 3
• Infill: 20 %
• Infill Pattern: Concentric/Gyroid

Based on my test prints the gyroid tends to be a bit more firm compared to the concentric infill that still firm while standing, but has a little more give putting the bottle down.

So: Gyroid firmer, concentric squishier.

You are going to find two .3mf Project Files with either a concentric or gyroid infill pre-selected and some other fine-tuned settings.

The overall .3mf Project files are based of @RolandDeschain Bambu Lab Overture Process Profiles which, for me, created pretty good results.

Like i said, it is nothing too fancy and just my first steps creating my own models.

I hope you like it and stay hydrated!
