Rhino HOTAS Throttle and Stick Mount for Ikea desk

I've always wanted a simpler way to mount my Saitek X-55 Rhino HOTAS (hands on throttle and stick) to my desk, and I finally got around to designing something.

This design requires the use of some 25mm square steel tube that can slide inside of the square steel tube that is part of the Ikea Jerker desk. I had to wrap a bit of electrical tape around the square tube where it slides inside to give it a more snug feel and to help hold it in place without needing to drill a hole for a pin.

I printed these using Polymax PLA which is surprisingly strong, and 10% gyroid infill, on my Prusa Mini+ but just barely fits corner to corner. Normal PLA might require full-size pieces at the rear of the throttle and stick instead of the short ones I'm using.
