inline tip-tilt optic holder V1

[NemoAndrea]

Challenge: design a 1inch optic holder that sits inline (0deg angle), offers tip-tilt adjustment and fits within a 30mm cage system.

Design f605377

The design consists of two rings that are hinged on two opposite piviots. The 2nd ring pivots relative to the first one. Adjustment is done via 2 M3 setscrews. Hinges are simple arced type (pre-tilted to 3deg) and about 3mm deep:

The 2nd ring also holds the optic, with the retaining lip tuned to the curvature of the lens. It is is held in place with a retention spring.

and the printed part (SLS nylon)

Finally, fitted with 80mm lens, but without the retention spring:

Points for improvement

• The adjustment points sit on the front (or back) side of the optic holder. This makes adjustment a bit tricky. With allan key it is possible, but it is signfiicantly less convenient than the 45deg optic holder.
• the initial spring strength is a bit too weak I feel, I will need to make it a bit thicker to resist the effects of gravity/vibration

The new hinges are 0.5mm thicker, now being 1.5mm at the thinnest point. Will be tested in the next SLS order batch.
