Trying another filament, with good result.
Bought this filament from 3DRax, mostly as I liked the color. Never heard of the brand, before, and at ~$19 per 1Kg spool (through Amazon Prime), fully expected some shortcomings.
Just ran through a spool of Matterhackers Pro PLA (~$45). As Matterhackers is about a mile from my front door, was - just a bit - hoping their filament was better. Admittedly I am a newcomer to 3D printing … but for my use, this cheap filament is better.
(Carving out a possible use-case. The Matterhackers filament seems softer. If I were making movie or cosplay props, and were going to heavily sand and paint before done, this might be an advantage. I am not aimed in that direction.)
I very much like the color.
