🚂 LocoMist - The Train Humidifier
A playful steam engine turned into a real cloud-puffing humidifier.
Designed as a cute companion for kids’ rooms, LocoMist splits into two parts: the top train body (with all electronics, filter, and chimney module) and the bottom water tank. Fill the “boiler” with water, drop in the filter, and watch it choo-choo mist through the smokestack.
📦 Parts List
- Mist Module (from Aliexpress, USB-C powered)
- Base platform
- Wheels + wheel pin covers
- Front cowcatcher
- Barrel (bottom + top halves)
- Cabin (bottom + top halves + roof)
- Chimney (with cable duct)

🖨️ Print Instructions
- Printed in PLA.
- Almost every part requires supports for best results.
- See included slicer screenshot for orientation and positioning.
- Use a brim for the cabin halves for best results.
- Recommended layer height: 0.2 mm; walls: 3.
🔧 Assembly Instructions
Bottom section (water tank):
- Insert the wheels to the base and lock with pin covers.
- Attach the front cowcatcher to the base (bit of glue might be needed, depends on your calibration).
- Place the cabin bottom on the base.
- Attach the barrel bottom to the cabin bottom + base pins.
Top section (electronics):
- insert the ribbon piece to the top barrel.
- Attach the roof to the top cabin.
- Insert the humidifier module into the chimney, thread its cable down through the chimney pipe → barrel top → cabin top. (it might be easier to first connect the pieces, then thread at once. You may need to lengthen the cables a bit)
- Seat the PCB in its drawer, connect module to PCB, and slide the drawer into the cabin top.
- Glue the top cabin and the top barrel lightly so the top stays as one liftable unit.
Final assembly:
- Fill tank with clean water.
- Place filter in the barrel top.
- Close with the top unit (chimney + electronics).
- Connect USB-C power.
- Choo choo → mist begins!
🌿 Functional Notes
- All water is held safely in the bottom tank.
- Electronics are isolated in the liftable top unit.
- Super glue is recommended to secure sub-assemblies → reduces risk of loose parts during handling.
- Designed to fit standard USB-C ultrasonic humidifier modules with wick/filter.
