Li'l Magnum! Fingertip Mouse Shell for Corsair Katar Pro Wireless

Be sure to check out the tips on successfully printing a good, light Li'l Magnum!

NOTE: Don't try to buy an ancient mouse like the Corsair Katar Pro Wireless!  I needed to support a different mouse to help me refactor the OpenSCAD source code for the Li'l Magnum!, and I have a few of these five year old mice on hand.  There is no good battery mounting solution.  I just soldered wires to a USB-C rechargeable AAA battery and taped that to the top of the mouse.

It might not be worth doing this mod even if you already own a Corsair Katar.  You might be able to buy a VXE R1 SE for just a bit more than the price of a pack of rechargeable batteries, and you will have a lighter, lower latency, more modern and rechargeable mouse.

This is obviously inspired by Optimum Tech's Zeromouse and Zeromouse Blade, but using FDM and a more affordable donor mouse.

The thumb and finger rests are in a reasonable spot for me, and the buttons are lined up well. 

My Li'l Magnum! with the Katar electronics, scroll wheel, and aftermarket USB-C battery installed weighs 26.13 grams.

• v0.1 - First STL to fit the Katar
  • It isn't as dialed in as the VXE R1 shell, but it is pretty good!
• v2.0 - Structural, weight, and ease of print changes!
  • Buttons are slightly more solid even with reduced weight
  • Button plungers adjusted
    • Square base instead of round for cleaner supported printing
    • Angled underside of paddles to reduce need for support materialAdded parametric side braces
  • Katar lens holder works better, but it is on the tight side!
