Well, I finally had a go at your bottle and it came out pretty good. I've been playing with Colorfabb PLA/PHA in white which is nice when you get it going but tricky to get right. I used a 150% flow setting for the first two layers to make sure it all knitted together then switched back to 100% after that. Not the best of photos but a nice print. Some facets on the curved surfaces but good, the stopper fits perfectly.
Can easily remove the facets if you want a smoother end-result. That's the result of the medium quality export from OnShape.
It's not really a problem I was just pondering if the effect came from S3D or the CAD side. It gives it a bit of a cut glass effect.
A Dragon in a Pie Costume wanted to see what the jar looked like using all the transparent polyesters I have on hand . Voila!
Another update for Pie (and anyone else looking for colors). I found some transparent/translucent yellow and orange PETG. The yellow is a bit milky but looks better in person than the photo. The orange is spectacular in person. The super dark black one is not transparent but does show how beautifully Atomic Filament's carbon fiber filled PETG looks. I also made a tiny change to the threading so that the engagement is a bit more positive. The STL files are attached. Update: Spoon Unit wanted to see my Simplif3yD profile I use for these. I think it's pretty middle of the road in quality vs. speed terms. The file suffix TG-L is for Taulman T-Glase and it's what I use for most PETG type filaments.
This is the RealFilament PETG in Translucent Orange. In reality it's a little lighter than portrayed and a little more translucent. https://www.amazon.co.uk/Real-Filam...1503574014&sr=8-6&keywords=real+filament+petg Also, attempting to photograph it in the most unfavorable way (light directly overhead) to show any banding: And for fun, let's complete the set by popping it on it's edge:
Another go at capturing the colour with a 'real' camera and natural light. Oh and it's half full of water to test for waterproof-ness.
It's really hard to capture on a camera is what it is. Their site just lists it as flourescent. It almost seems to glow though, as if it contained nuclear waste.
Added a hex bottle to my original thing. The square bottle top (which is round) will fit it. https://www.thingiverse.com/thing:2093082
