A subject firstly spoken about in the Homey Antenna Mode thread is an case mod. based on this interest I’ve created a rough 3d model in which the dimensions are correct. the model has 125x125mm base because my 3D printer does not exceed these dimensions. The height in this model is 60mm.
Please let me know what you think, and what can be done to improve this. Thanks to community member Sjalabert for opening up his homey to supply me the dimensions of the internals.
