Nuka Cola bottle

Here's a Nuka-Cola bottle from the Fallout games.

I designed it mainly because I was curious how to model a bottle in Fusion 360, so I put a bit more effort in it than planned and made a nice cap for it and engraved the logo into the bottle.

Print Settings

Printer Brand:

Ultimaker

Printer:

Ultimaker 2

Rafts:

No

Supports:

Yes

Resolution:

The bottle 0.15mm, the cap 0.1mm

Infill:

0% (Vase-mode), the cap is to thin for infill

Filament: Colorfabb / Ultimaker PLA and PP multiple

Notes:

The bottle is printed in vase-mode with a 0.6mm nozzle and 0.15mm layers out of Polypropylene, surprisingly it's even watertight.
The cap is printed in PLA with a 0.25mm nozzle and 0.1mm layers. For the text I set the line-width to 0.2mm to get some more details.

Since my printer can only load one material, the base of the cap was printed first with red PLA (that's why there's a version without the logo) and on top of that I printed the logo with white PLA (sliced with 7mm z-offset to get it on top).Sadly the white smeared a bit (because of no retract 🤦‍♂️).

For the bottle I used a brim, the cap was printed without anything. Since the cap hat to be oriented that way so I could later print on top of it, it uses supports.

I thought about PETG to get the bottle clearer but it should be flexible to get the cap on and off and I thought with Polypropylene the chances a higher to get it fairly watertight and the layers wont seperate when bending it a bit. (Additionally the PP was laying around a while and I wanted to use it for something).

Post-Printing

More like mid-printing:

As I said before the cap was printed in two steps, at first the red cap itself (the file without the logo), then I left it on the warm buildplate so it stayed in place, changed the filament to white (it took quite a a while until all red stuff was gone and it was clearly white). After that I took the file with the logo, moved it in the slicer down to -7mm (so only the logo was sliced) and set an z-offset to 7mm (the height of the already printed cap).

I find that worked fairly well (in general) for two colors (of if you want to put more effort into it, you can change the filament even more often to get more colors). The only thing that is important is that you set the z-offset correctly and switch off skirts/rafts/brims.
