Stronghero3D 1.75mm PLA 3D Printer Filament Rainbow Wood Marble Carbonfiber WarmGrey Each 200gram Bundle Pack Spool - Dimensional Accuracy +/- 0.05mm

3 of them came sealed nice and tight. 2 came non vacuumed packed. I have Not printed anything with them yet. And there is a desiccant bag in all of them. I opened one of the non vac packed filaments and the dimensional accuracy was within the advertised limit. Tested about a 3 foot length in 10 or so dif places only one out of its range was 1.69 mm rest were 1.73-1.78 more often than not 1.75. I have not printed yet with any will update when I do. And change rating based off Print quality. One more note, The rainbow filament is more of a watermelon with only there being green and pink in it. In the end I could not use any of them as they all caused clogs that none of my other filaments caused.

Everything appears good, however I have not been able to get the carbon fiber to print correctly. It appears to have absorbed moisture before packaging. When heated, it pops and spits and does not adhere properly.

Marble wasn't adhering well with constant fails but the wood filament printed extremely flawlessly with 0 fails. Was actually able to stain the wood filament.

This is a really nice set. It comes with Warm Grey, Rainbow Wood, Marble, Carbon Fiber, and Rainbow. The Rainbow and Rainbow Wood I'm sure differ from package to package, my Rainbow Wood starts out with a darker brown then goes to a lighter one, and the Rainbow is pink and yellow.I've only tried the Warm Grey so far but they all look good. They all came vacuum packed with a desiccant. I was actually the least excited about the Warm Grey, since unlike the others it isn't a specialty filament just plain PLA, but when I printed it I fell in love with it. The only finishing I did to the battery holders in the pic was to snap the pieces together and glue on the letters - that is it. And it looks fantastic. The grey printed really smoothly with a nice finish. In fact I immediately went to buy a full roll of the Warm Grey but it doesn't seem like they sell it!I'm not sure if this pack is from filaments they've discontinued or what, but when looking for the Warm Grey I noticed that you can't get most of these options in full rolls. Disappointing, especially since some like the Rainbow Wood are unique to Stronghero3D.
