Communities related to r/3Dprinting, with what each one is for and how it differs. Member figures come from SubMouse's safe-for-work directory.
r/3Dprinting (about 3.5M members, directory rank #299) is where makers learn about and discuss 3D printing and printed parts. Blender modeling, component-level electronics and general handmade project showcases each have clearer homes when the thread is not specifically additive manufacturing.
Noisy directory related names unrelated to making are omitted.
Stay on 3Dprinting for printers, filament and printed designs. Use blender for 3D modeling and rendering in Blender, electronics for circuit-level discussion, and somethingimade to showcase finished DIY projects of any craft.
