Jack stands for the T4 Quad found here on Thingiverse. I modified the body of the T4 for my own purposes to be wider and longer. I have a Hero3+ GPS on the OEM arm that I don't want to take off when I flip the quad over to work on. So thus here are jack stands or maintenance stands for your T4 Quad. The mouth of the stand matches the geometry of the arms, but it is a little oversized so the drone sits right on the stand. Additionally I added pass through hole that you can use to put some velcro straps to hold the drone, just incase and it doesn't slip of the stands as well.

I wanted to be able to put these stands in a pelcan case and take them on the goes as part of the drones load out, so I printed them with a 30% infill using the Gyroid infill pattern. But if you keep them in your drone hanger full time or careful with them you could easy print at 10 or 20% infill if you want to save filliment.
