This is based on Marco's stackable "small" design (for 6' or shorter cable lengths). It can be stacked with his standard version 6 design, and the components are interchangeable, so tops of his version will fit this and vice-versa. If you've successfully printed his original design, this will be exactly the same.
My pictured versions are made from Overture PLA (light gray) and Bambu PLA Tough (dark gray), respectively. Printed on a Bambu P1S with a .4mm nozzle and .24mm layer height with 15% infill.
Note: If you are using a non-Arachne slicer you will want to select Arachne for wall generation, such as in the case of Bambu Studio 1.8. This prevents a small gap forming where the wall thickness is about the same as the nozzle diameter.
The author remixed this model.
I edited Marco's design to keep all of the great features, but create the perfect sized pocket for the Apple Watch induction charger.
