I wanted to upgrade my carrying case for my new X20HD from the soft wall case to something more heavy duty.
1st up the foam insert for the provided case is really good, way better than pick foam so I needed to work around that.
1), the case
I found the modern solution in the Harbor Freight Apache cases, and foam insert fits inside the 3800 model

Sometimes they offer coupons so be on the lookout.
There are some alternate online options but the size may be different than what is covered here
As for the hinge to handle direction there was a 1/2″ gap so I used some high end packing foam in a nice dark grey from my Creality Ender 3D printer for that
Speaking of witch Creality is my go to for 3D printing equipment, its worth checking out

A recent review of the machine that did the 3D printed parts on YouTube:

2), maxing out the foam insert space
The next part in the puzzle was the 4 in 1 module I got to work with most of the protocols out there,
For this I picked the iRX4 Lite from iRangeX = https://amzn.to/4k5ZMF6
I had to cut out some of the foam insert for this to fit. I’m surprised that FrSKY did not already have this area opened up as it would save them foam / cost and weight.

3), interacting with the X20 Screen
While the X20 series is amazing technology and the screen is something to behold its also alot of small menu selections for average fingers to interact with.
For this part I found a good stylus on Amazon that works well with the screen and makes it easier to use = https://amzn.to/4qcRAoe

4), protecting the screen
I wanted to cover the screen while in the case or just when sitting out side, also needed a way to hold onto the stylus in part 3), enter the cover
Designed in Rhino 3D one of my favorite Cad Programs this easy to print cover takes around 1 hour on a modern core xy machine
I had to put the FrSKY logo on it because why not, with that in mind I have it up on Thingiverse for Free = https://www.thingiverse.com/thing:7285780

5) filling the void
I still had several inches to take up in the Apache case so I decided to make a storage box for anything related to the X20,
The lids I went to town and made them have an ISO grid pattern as its stuck in my head after working on Aircraft Gas Turbines for a lot of my career. Also has a kind of NASA Equipment look to it. Silk / Metallic filament is a must for this!
I have the .3dm & .stl files up on Cults3D for this one: https://cults3d.com/en/3d-model/gadget/frsky-x20-and-hft-apache-3800-storage-box
For all the 3D printed parts I used my go to brand Sunlu available with quick delivery from Amazon
