Monster Mouth modified (stronger weak spot)

thingiverse

Created a version based off the 30mm model with a stronger neck, and then flattened out the contact patch. You are forcing the part to bend to make contact with the original design, which seems to make the neck even weaker. There is an angle at the back side, so if you fit this flush with your desk edge it won't lay flat. I have a small space to grab on, so I don't come close to the back so I used this space to gain strength on that weak joint.
