Currently, the Celestron Nexstar Evolution hand controller (HC) clips onto the tripod. As the telescope spins it binds the cable up or worse, breaks it. So, I designed and printed this.

This attaches to the side as shown.

To complete, you need:

• One 3 inch 1/4 inch bolt 20 thread
• One 4 inch 1/4 inch bolt 20 thread
• One wing nut 20 thread
• One acorn nut 20 thread
• 1 nylon lock nut 20 thread
• 1 washer

Assemble:

• The three inch bolt hold the two parts together, use the lock nut, trim to size.
• The four inch bolt clamps it together. Find the right length fully open with the wing nut and washer, cut it to size and use the acorn nut with a little thread lock. The acorn nut will prevent you from losing the wing nut (ever look for a wing nut in the dark? It's not fun...)

I sprayed Plasti Dip on the griping surfaces so it wouldn't slip up or down.

Being for a Celestron telescope, naturally I printed it in translucent orange PETG.

Note: Added an STL and STEP for the HC to be on a hinge to rotate 90 degrees.

New files:

• Side_Braket_for_HC_with_Hinge.step
• Side_Braket_for_HC_with_Hinge.stl

Just add a new bolt and wing nut.
