Keychron Q11 Split Keyboard Tenting w/ optional wrist rests and optional screw attachments

This is a remix of @PaulGrimes_855599's tenting base for the Keychron Q11 split keyboard. This design is set up for Keychron's own wooden palm rest but it should work fine with many others too.

Some problems I had with the original and my attempts to fix them:

• The connection between the keyboard and the tenting base failed for me (the rubber foot pads started to detach)

  • I changed the way that the keyboard attaches to the tenting base. This version of the base fits into the foot pad area on the Q11 and can accept screws to rigidly connect the base to the keyboard.

• Too flexy side to side

  • I tightened up the spacing in the “dovetail” or “puzzle piece” to reduce flex.

  • I made a version that eliminates the dovetail entirely to eliminate flex.

• When using the tenting base without wrist rests, the base sticks out from under the keyboard

  • I moved the  location of the dovetail to hide the base under the keyboard

There are two models:

• “removable_wrist_rest” has a dovetail between the keyboard and wrist sections so that you can separate them.

• “rigid_wrist_rest” has no dovetail. This is what I am using and I have tweaked this more than the other model.

Required modifications:

• Remove two adhesive foot pads from each side of the keyboard.

  • Remove all of the pads if using a design with inner and outer feet.

• Drill ¼" holes into your wrist rests. I included a drilling guide pdf to take the guess work out of it. Make sure it's printed 1:1 before using!

Optional modifications:

• To attach the support to the keyboard with screws, remove the bottom cover from your keyboard, drill a hole in the center of the two foot pad wells, and screw them together. I used a 1/8" bit and m3x6 flat head screws. Wafer head screws would be better.

• To change the tenting angle, fire up Fusion 360, modify tab → change parameters, and look for “TentingAngle”.

• For more grip and stability, I put a layer of 2mm anti-slip "rubber" on the bottom of my supports. I used this on PLA and it works quite well.

Not good for:

• Tenting angles over ~15deg. Play around with the parameters and you should see why. At 25deg, each inner foot extends 1.25 inches past the keyboard.
  

Version history:

• V3: eliminated the separate wrist rest pegs from the original model. Printed them directly on the tent. It turns out this was a bad idea since the pegs are weaker and will sheer off.

• V6: reverted wrist rest pegs to be printed separately and inserted into the tenting base.

• V7: added outer supports for stability and to prevent "tipping over"
