I've used it a few times right now, still happy with it! (UPDATE) I've added some pictures of it. Works great! Mostly connected by M5 bolts/nuts including washers to spread the load.
Cage is 3 parts for easy printing. Handle is two parts du to modularity. You may want to increase height, move forward or backwards, ect. Some parts have holes for not yet designed extra's. (Example but no need for by myself right now: 3d printed side handle, monitor support, HDMI/Sound cable strain support).
No supports, some holes are 1 layer closed for easy bridging. At least 5 perimeters (how many I have used) and ~40% infil to get to a strength that I trust. Use PETG (my choice) or stronger. It can of course be flexed at high strength, but under the load of a camera/lens will not flex a bit. I totally trust my camera/lens to it, but use at own risk! ;)
Fits a A7IV perfectly, battery still removable. All buttons and side ports reachable. Sony lenses like 50/1.2 20/1.8 fit no problem.
You need to find a 1/4 " camera plate/tripod screw. Got mine out of a box with old scavenged parts… mabey try an old tripod plates screw.
