OCXO Enclosure Improved

Enclosure for low cost 10MHz OCXO found all over the Internet. Based on theihdes' original work.
Changes:
* Tuned the holes to fit the ports snugly
* Reinforced the walls (I found the clip part of the original too thin to even survive the print)
* Flipped top and bottom
* Thinned to 25mm
* Added vents on the (now) top half
* Added text to (now) top
* Added recesses for 8mm Little Rubber Feet
* Adjusted vent spacing to allow access to the trimpot without opening case

Ventilation will work better in the original orientation but I wanted the text (and dust resistance). :) You can always lay it face down if you need to.

Recommended to print in ABS, as the device gets quite warm (It's literally an oven, after all!)

Supports recommended for the vents in the top section.
