Badgeware 2350 Case Files: What Exists, What Doesn’t, and How to Build Your Own
No official CAD for Badgeware 2350 cases — but you have options
As of mid-2026, Pimoroni hasn’t released CAD or STL files for any part of the Badgeware 2350 case lineup: no front or back shells, no extender rings, no snap connectors. The GitHub repositories for each badge (tufty2350, badger2350, blinky2350) are almost entirely software and firmware. The hardware directory, where one exists at all, contains schematics rather than mechanical models.
That’s a real gap. The 2350 series introduced polycarbonate cases as standard across the lineup — a genuine step up from the bare-board Tufty 2040 — but it makes DIY modification harder. Without reference models you’re measuring by hand with calipers.
What community makers have done for the Tufty 2040
The Tufty 2040 spawned a reasonable collection of third-party case designs on Printables: full badge holders, sandwich-style cases with GPIO access, portrait-orientation shells, simple badge holders. None of these fit the Tufty 2350 directly. The PCB dimensions and case geometry differ, and since the 2350 ships with a polycarbonate case already, the need shifts from “provide a case” to “extend or modify the existing one.”
These 2040 models are still worth downloading as dimensional references. Some include source files (Fusion 360 or OpenSCAD) alongside the STL, and the overall badge proportions give a useful baseline even when you’re modeling from scratch for the 2350. The Tufty 2040 Case by hsavior and the Tufty 2040 Badge Case by Commputethis are two of the more complete designs to start from.
The GitHub Universe 2025 badge and its sensor plate
The badge Pimoroni built for GitHub Universe 2025 is a Badger 2350 variant with a few hardware additions: IR transmitter and receiver, dual Qwiic/STEMMA QT ports, and an extended back plate that creates a small mounting shelf above the main board. That’s the feature referred to as the “extended plate” — and it’s a sensible design for keeping sensors inline with the badge face without awkward external cabling.
The badge firmware and app ecosystem are open source — the badger.github.io community hub collects hacks and experiments. But the mechanical CAD for the case extension isn’t in any of the public repositories as of mid-2026. The plate geometry is specific to that custom hardware revision, and Pimoroni hasn’t published it into the open badgeware repos.
The closest you can get without official files: measure the mounting points physically. The Qwiic port is a standard JST SH 4-pin 1mm-pitch connector, so a sensor plate that routes a short cable to it cleanly is achievable with careful measurement and a few print iterations.
Building a sensor extension plate for the Tufty 2350
If you want to add a sensor platform above or behind the Tufty 2350, here’s the practical approach:
- Measure before modeling. Calipers on the overall case dimensions, the USB-C cutout position, the case seam lines, and the lanyard slot give you the reference geometry. Product listings for the Tufty 2350 include overall outer dimensions as a starting sanity check.
- Design a friction-fit surround or back plate. A thin-walled shell (1–2mm walls) that captures the existing polycarbonate case works better than trying to drill into it. Leave ventilation slots if you’re enclosing any sensor that reads ambient temperature — the 2350 runs warm under load.
- Route sensor cables through the Qwiic port on the back. A well-placed cutout in your extension plate keeps the cable tidy and avoids mechanical stress on the connector.
- Print in PETG rather than PLA. Conference badges spend time in warm pockets and occasionally under direct sunlight. PLA starts to creep around 60°C; PETG handles it with margin to spare.
Where to watch for official files
The pimoroni/badgeware-docs repository is the most likely place Pimoroni would publish case files if they do. The issues tab already has related requests — worth adding one to show demand. The pimoroni/badgeware-contrib repository is the designated spot for community contributions and is a reasonable place to share any design you produce.
Searching Printables for “Tufty 2350” returns little right now, but a saved search takes about thirty seconds to set up. Once one or two designs land there, more tend to follow quickly.
