I wanted to mount a USB3 hub on my Ioptron Tri-pier. There are holes on the pier that I can use to mount the hub. However, I didn't like mounting a flat surface of the hub to the round surface of the pier directly. I wasn't able to find such an adapter or even a 3D printed one. So I made a set of column adapters for my hub that I think will be useful for others.
Here's how my adapter and hub mounted on the pier looks like:
The pair of adapters after 3D printing are shown here:
Each set consists of
- (a) 2 column adapters that has a hole and a slot for 1/4"-20 bolts.
- (b) 2 saddle washers for securing the adapter to the pier.
Here's a photo of the adapter with the bolts that I used:
- (a) 1/4"-20 1/2" socket heat bolt for securing the adapter to the pier together with the saddle washer.
- (b) 1/4"-20 3/4" button head bolt for securing the hub to the adapter.
These column adapters should be compatible with other 6" piers like the Astro-Physics 6" Eagle Adjustable Folding Pier.
