Accessory holder for Sky-Watcher Extension tube

I created an accessory holder to attach to the extension tube of my Sky-Watcher SA GTi Eq mount.

To prevent damage, I used M6 nylon screws and nuts to attach the bracket to the extension tube. I used M5 wing nuts and bolts to attach the accessories. The main hole has a diameter of 55.6mm. Make sure it fits your extension tube.

So far I've only created one accessory, which is a basket to support my power bank that powers the assembly. Configure the bridges well so that supports aren't needed. You may need to print upside down. New ideas are welcome.

If you want to create you own attaches, you can follow these dimensions:

(dimensions in milimeters; I don't remember why 15.17mm, but it worked; if you want, you can try to round to 15mm).
