Goal

Hold the glass tight down on the bed.

Constraints

Don't require a trip to the hardware store
Don't require partial bed disassembly
Minimize interference with head motion
Minimize print area reduction

Design

Clips are tapered and have an opening slightly less than 7mm at the front to grab and stay on. I will update this posting if I find any flaws or improvements.

Printing

I used PLA to eventually discover the failure points. I recommend you use ABS or NY.
PLACE OBJECT VERTICALLY (like a skyskraper, with "C" face on the bed). Duplicate x3 total copies.

Installation

See picture. Put on one side of clip and put counter pressure on opposite side of bed with your hand while installing. Avoid blocking the home position with the front clip.
