The kit

You get all parts as STL – pre-arranged on 12 print plates by color and individually as well. No part needs supports, a single-color printer is enough.

The water wheel (Ø 88 mm) sits on an octagonal shaft that runs through the gable wall into the house. Inside, the cog wheel with 16 cogs meshes with the lantern pinion with 8 staves and turns the vertical spindle. The runner stone therefore turns twice as fast as the wheel.

It assembles without glue. Inside you find the grinding frame with hopper, flour spout and flour box, and above it the loading floor with railing and ladder. Outside belong the mill race with water, the flume and a sack hoist on the gable.

Notes

  • Pegs and slots are built for 0.20 mm clearance per side, set more generously than before after test prints so nothing needs trimming. The included fit test shows whether that suits your printer.
  • The gearing has been checked on the computer for meshing and clearance. How easily it runs depends on your print – the guide shows what helps if the wheel turns stiffly.
  • The finished model has many very small parts and is not a toy.
  • The files are for your private use – print them as often as you like. You may not pass on, upload or sell the files themselves.
