Micro Magic redesigned gooseneck using ball bearings

Have upgraded my Micro Magic with a new gooseneck. Have used imbus bolts of M1.6 8 mm long. The ball bearings have an inner diameter of 5mm, an outer diameter of 8mm and are 2.5 mm high.

The mainboom is a carbon pipe with an outer diameter of 5 mm. The connection between de mainboom and gooseneck needs to be printed twice, glued together with 15 mins epoxy and again glued with epoxy into the mainboom.
