Berlin Clock – Mengenlehreuhr V1

A new, complete version of this model is available on my profile → https://www.printables.com/model/683696-berlin-clock-mengenlehreuhr-replica-v2

This is a miniature replica of the Berlon clock "Mengenlehreuhr" designed by Dieter Binninger.

• It's a Clock that works on the mathematical principle of set theory.
• The working principle is simple :
  • There are 24 light signals arranged on 5 levels.
  • The round box at the top shows the seconds (by flashing once every second).
  • The first led raw contains 4 led and each box represent 5 Hours.
  • The 4 boxes below each represent 1 hour.
  • The third row contains 11 boxes which represent each 5 minutes. (note that the third, sixth and ninth led of this row are red to represent three quarters of an hour more easily).
  • The 4 boxes in the last row each indicate 1 minute.
  • The clock reads top to bottom.

How I Designed This

Global structure

• This project was entirely designed and modeled with Tinkercad.
• The model has also been modelized in order that the front face is on the heatbed.

By printing with a Prusa i3 Mk3s+ (or earlier) with a textured PEI Powder-coated Steel Sheet, it is possible to get a "mat" effect.
