Rectangular Scanner Under-Table Mount

I'm in need of a custom mount for a rectangular scanner. This mount should be designed to hold the scanner securely under a wooden table. Would need to have screw holes on side to keep scanner from going out of holder. Also, would need place where screw would go up top to be adjustable.

Key Requirements:
- Design needs to accommodate a rectangular scanner.
- The mount will be installed under a table.
- Must be made of 3D printer plastic filament.

Ideal Skills:
- Proficiency in 3D design software.
