About this 3D model

I made a Wrist rest for the Dactyl-ManuForm 5x6 Keyboard (https://thangs.com/designer/ZackFreedman/3d-model/Dactyl-ManuForm%205x6%20Mechanical%20Keyboard-10466) without any aditional Hardware or Glue. It simply gets clampt underneath to of the already exixting Screws. Because the bottomplate ist completly flush anymore, there is a little bit of additional flex but the border around minimises it, so you (i) can't notice it.
