A short, curated guide — not an automatic related dump. Figures come from SubMouse's safe-for-work directory when we have them.
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.
r/3Dprinting — Welcome to R/3D Printing! Come for the Benchy, stay for the Calibration!
/r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing and development of 3D printed parts and devices.
Blender - The Freedom to Create
When to choose it: 3D modeling, animation and rendering in Blender rather than running a printer.
Why it is here: Public description: Blender community for free/open-source 3D modeling, animation and rendering (about 1.5M members, rank #727). Shared 3D-maker neighbourhood.
How it differs from r/3Dprinting: Software modeling/render focus versus physical 3D printing.
Electronic circuits at the component-level
When to choose it: Component-level electronic circuits that may accompany printed enclosures.
Why it is here: Public description: discussion and news about component-level electronic circuits (about 1.4M members, rank #740).
How it differs from r/3Dprinting: Circuit electronics versus additive manufacturing.
Something I Made
When to choose it: Showcasing finished DIY projects of any craft, not printer troubleshooting.
Why it is here: Public description: showcasing and celebrating DIY projects for crafters and beginners (about 3.1M members, rank #341).
How it differs from r/3Dprinting: General handmade showcase versus 3D-printing craft.
