I’m in the process of replacing all my single-color christmas lights with addressable RGB LEDs, but the 12mm “bullet” form factor of them is different from the traditional incandescent mini lights, the 5mm wide angle LEDs, etc.:
You’d think they’d make C6/7/9 bulb covers that attach to them, but I have yet to find any for sale, anywhere. As such, I want to 3D print some, along with 12mm bullet pixel-sized replacements for my snowflake lights:
What’s some good filament I can get that will be reasonably clear and stay that way (without yellowing or getting too brittle) for several years’ worth of Christmas seasons, despite UV/rain/cold exposure?
(Bonus question: anybody know a good way to model the facets in those “strawberry” lights? The C7 bulbs on Thingiverse, such as this one, are all smooth, LOL.)
Edit: by the way, to be clear (pun intended): I don’t need optical clarity like the lens guy; scattering the light is fine. (In fact, doing that on purpose is kind of the point of modeling a faceted C7 bulb instead of a smooth one.) I just want to make sure that whatever part of the filament that doesn’t manage to be transparent is white, not tinted some dingy color.
I do happen to have some Inland “natural” PLA laying around and did a test print in that. It’s not too bad – only a little bit yellow at the wall thickness I’m using – but I fear for how it will hold up over time.

I’ve run Overture cardboard spools in my Sunlu filament dryer directly into my printer many times with no incident. It has rollers for the spool edges, no center axle. And other brands’ cardboard spools as well.
Ah. Well bambu ams has issues with their rollers slipping on cardboard spools unless you print a clip on ring that covers the outer edges, only because bambu uses the rollers to backdrive the spool when unloading. Not so for basic feeders
