A watch-and-read pick: the embedded video plus the original write-up together give one of the archive's more complete looks at 3d printed parts.
Heat, Hash, and Home Labs: How 3D Printing Is Supercharging Bitcoin DIY (with CryptoCloaks) Sponsored note: This conversation was brought to you by River —a Bitcoin-only company that builds its own infrastructure, encourages self-custody, and offers fee-free DCA .

The Big Idea: Turning Waste Heat into a Feature Bitcoin mining throws off heat; most people treat that as waste. Rick V. of CryptoCloaks treats it as a product brief.
CryptoCloaks has spent six years designing 3D-printed parts for bitcoiners—everything from cold-wallet mounts to miner shrouds and full node cases. Their latest obsession: quiet, household-friendly space-heater builds (starting with the Antminer S9) that warm rooms while hashing sats. Think “smart space heater” that pays you back.
Why it matters: If a miner also heats bedrooms, workshops, or whole homes, the economics of residential mining change. Instead of competing with your HVAC bill, your HVAC is your mining bill.
Rick V from CryptoCloaks | How 3D Printing Can Make Your Bitcoin Mining Operation Better 3D Printing’s Leap: From Weekend Hack to Production Tool Rick’s timeline reads like a speedrun of the entire industry:
Then vs. now: A simple wallet mount went from ~5 hours per print to ~20 minutes on modern machines.
Better calibration: Auto-bed leveling and sensors (even LiDAR on some models) tune flow and speed on the fly for cleaner parts at ludicrous speed.
Materials: For mining enclosures, PETG beats PLA —it tolerates higher temps (think 80–95°C chip targets) without softening or warping.
Takeaway: Rapid iteration means bitcoin hardware ideas can move from CAD to usable plastic in a single afternoon, without tooling or molds.
The Space-Heater Build: Quieter, Cooler, Safer CryptoCloaks’ S9 space-heater is the flagship example of practical mining:
Noise control: Swap the stock screamers for quieter Noctua 140 mm fans; replace the PSU fan if you’re running low wattage.
Thermals: Tune chip temps around ~80°C for winter “set-and-forget” use; print heat-exposed parts in PETG .
Ducting: Their fan shrouds snap to standard 6–8″ ducting so you can pipe heat to a room, a plenum, or outside when seasons change.
Standardization: Shrouds normalize every miner’s exhaust to an 8″ round —swap S19 ⇄ M30 without cutting new foam every time.
