This is one of my all time favourites- instead of a pendulum, this escapement uses a ball bearing rolling along a track to keep time. At the end of the track, the escapement hits a trigger which causes the track to slant the other way, starting the cycle again.

The video below shows how easily this mechanism can be assembled!

The STL File:

Prints on all standard 3d printers without supports, requires the following additional parts to assemble:

• 4 M4x12| 2 M4x20 Screws (https://amzn.to/3zgQb8f)
• 8 M4 Washers (https://amzn.to/3SApQsQ)
• 6 624Z 13mm OD/4mm ID Bearings (Like these https://amzn.to/3DtUUpH)
• 1mm Nylon String or Fishing Line (I used string from this set https://amzn.to/3DtUUpH)
• 7 Ball Bearings (https://amzn.to/3stFWKd)

Recommended print settings:

Layer Height: 0.2mm Nozzle: 0.4mm Infill: 15-18% Total Filament Required: ~200g Minimum Build Plate Required: 205x205mm

**All the files have been pre-oriented to save you some set up time! All you need to do is drop the parts into your slicer and hit print!
