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.
Any opinion on specifically which clear PETG I should get?
Never had Overture steer me wrong. I use Overture almost exclusively for ASA and they’re reliable, don’t see any reason why they wouldn’t work for PETG too.
Their cardboard spools aren’t Bambu AMS compatible (or compatible with any filament solution that relies on spool edge rollers), so keep that in mind.
Inland is Microcenter’s in home brand and I’ve heard good things about them too.
Is there any reason to think Creality would be a particularly good choice because it matches the brand of my printer? (If not, I’ll get the Overture.)
Not really any correlation. Plastic filament is plastic filament. About the only outlier would be Bambu with their rfid AMS identification system. But even then, I’ve put 5 different brands through my Bambu printer and honestly, Bambu filament has performed the worst lol (it’s more wet than most out of the box and needs drying).
?
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.
