‘Brought to you by big oil’: US billboards call out companies for record heatwaves

I’d just like to report that I successfully changed the gender in my passport.
Unfortunately, I overpowered the gender-change spell and accidentally transed the King:
@janantos @ncweaver @andykm i printed butterfly wings which i attached with metal wire.. and it must have been outside here for at least 5 years, partial shade, probably little shade in winter. I don't see/feel difference in material property.
Similarly the biodegradability is.. very slow at best. Hopefully as microplastics in the water the hypothetical biodegradability is better...
@ncweaver @andykm PLA will not really melt until about 180°C, but it will get soft from about 50°C (the exact values ofc depending on make and brand, bit it's in that region). Generally not advised for any kind of outdoor use.
I once tried to print the model in PETG, but the stringing made it not work at all.
Warping is much more likely than melting. And with that kind of fine detail, a little warping would be enough to make it not work.

There is a tiny bit of magic inside...No batteries, no motor, no electronics... It's all just a really super-fancy shadow show. The shape of the sundial has been mathematically designed to only let through the right sunrays at the right time/angle. This allows to display the actual time with sunlit digits inside the sundial's shadow.The sundial displays time (with actual digits !!) from 10:00 until 16:00, updating every 20 minutes.You can precisely adjust the displayed time simply by rotating the gnomon (the magic box that displays time). So you can even adjust for Daylight Saving Time.You'll also need :--- an (empty !) jam jar--- 3x M6 screws, flat head, length = 20 mm--- 1x M6 screw, flat head, length = 50 mm--- 4x M6 nuts--- 4x M6 washer, outside diameter < 14mm[ FRANCAIS ]Tadam !Un cadran solaire qui affiche l'heure dans son ombre avec des vrais chiffres !

@andykm Sweet! Is it on the thingiverse or somewhere else online?
(Already saw the answer, sorry for asking again.) 🤭
@andykm That is an extremely cool idea!
Somewhat similar to this one?
