Lighthouse Leuchtturm Hoek van Holland

History

This is a replica of the lighthouse which stands at the mouth of the Rhine into the North Sea (Hoek van Holland, Rotterdam).

A very similar model stands on Oberalp Pass at the source of the Rhine.

I built one model with aprox. 3% of the original size (~30cm height) and one with 4% (~40cm height) of the original size.
The files are accordingly named Lighthouse3 and Lighthouse4.

For both sizes, it is essential to use a printer in the SLA process for the detailed parts.

I don't have a SLA printer myself, but you can make most of it with a FDM printer and organic supports. So you only need the parts with small details from SLA printing and they can be ordered affordable online.

Everything must then be glued together. I mostly used 2K glue. The windows can be cut out of a PET bottle.

All dimensions I have estimated from pictures and little optimized in favor of 3D printing.

Later I also added a rotating reflector from an old flashlight.
For the 360 degree rotation I have installed a cheap 9g servo (modified to 360°) and the following sliding contacts:
