Rear panel for Tektronix 2225 oscilloscope

This is a 3D-printable replacement rear panel for a Tektronix 2225 CRT oscilloscope. If your scope, like mine, is missing its original plastic rear panel, this will provide:

* Rear feet. Rubber stick-on feet (≤ 14 mm diameter) can be inserted.
* Protection for the exposed end of the CRT.

It does not have any power cord management features.

It requires 180 mm × 132 mm of print area, and prints in two parts to glue together.
