Normally, I just run an antenna out a window and be done with it, but without modifying my weather radio, and external antenna wasn't an option.

Enter the general purpose shelf. This is designed to be hung with two screws and there is a slot down the back in which you can run the power cord. It's simple and effective. What more do you need?
Print it with 1.6mm walls, 1.0mm top and bottom at either 0.2 or 0.3mm layer height with 20% infill in the orientation presented. Supports are not necessary.
NOTE Due to either a Thingiverse bug or (more likely) shadowbanning, my models no longer show up under the [Newest] listings. If you want to see more of my models, please be sure to 'follow' me. If you print this, it would really help if you'd post a 'make' so that others could find this model.
