I think this file is now corrected. I had found a flaw in this thing after I had printed it successfully but also after I uploaded it. Not sure how it printed the first time but here it is again. This thing is a case for a Thumbstick of the kind that you can find on eBay for connection to an Arduino or Raspberry Pi. Nothing fancy just functional for what I needed. Note that there is a second version in the Sketchup file that is still under development.Print, insert thumbstick, snap together.
