While traveling by foot or on horseback can be adventurous, portals are key if you want to change planes or dimensions quickly. It gets even better when the whole portal starts spinning. By using a small stepper motor together with an Arduino nano (or compatible) you will be able to add some motion it the otherwise static scenery.
– All STLs needed for a static or motorized portal
– A PDF with diffrent color choices for the portal plate
– PDFs with instructions on how to connect and program the needed electronics
You will get the .STL files in a .ZIP package, to print with a 3D Printer.
In order to motorize the model you will need additional parts that will cost you a few dollars/euros.
Suggested printer settings:
0.2 mm layer height / 10% infill / no support
