## What it is
PositronV3 is an open-source hardware design for an upside-down, compact, portable, fast 3D printer that folds up and fits in a filament spool box. This repository hosts the design files, BOM, and documentation, and is now marked LEGACY in favor of the Positron3D/Positron repo with LDO-produced kits.

## Use cases
- build a compact portable 3d printer
- self-source a fast travel 3d printer from a bom
- find open-source 3d printer cad and design files
- modify and improve an upside-down 3d printer design
- print at 200+mm/s with a printer that fits in a bag

## When to choose
- you want to build a highly portable, fast DIY 3D printer from open-source files
- you enjoy iterating on functional-prototype hardware designs and sharing improvements

## When to avoid
- you want a finished, warrantied consumer product
- you need current files - this legacy repo is superseded by Positron3D/Positron
- you are looking for software rather than hardware design files

## Facets
- artifact type: application
- maturity: maintenance
- function: simulation, developer-tools
- domain: hardware, cross-platform
- platform: embedded, cross-platform
- tags: 3d-printer, hardware-design, openscad, klipper, diy-hardware, portable, legacy-repo, automation
