7, CAD bracket version 3.0, part 4:

Info:

We had a clear sky last night so it's hurry to get these parts working now.

3D printing bracket version 3.0:

More than halfway through, the reinforcement edge is printed.

This time everything looks to fit perfect, just a small part of the reinforcement I have to cut down 2 mm. It struck in the motor when it is in its most left position.

A rectangular hole was added in last minute at the upper part, for a stripe or a cable.

Motor mounted, most left position.

Motor at most right position. It can be adjusted +/- 5 mm. In a later version I shall widen the bracket so I can have the reinforcement all the way from bottom to up.

Control unit installed in its holder, to my surprise it fit perfect, no need for a strap around it.

This is the 16 teeth I have mounted on the motor's 6 mm shaft.

Much more compact now and it will also fit my later Pentax medium format lens, or any other lens as well.

So much better everything is now compare to how I had it earlier.

When the timing belt is set with correct tension the motor is almost exact in its middle position.

There will be a version 3.1 later which I put online to download, but now very busy with next holder, the holder to the auto guiding camera and lens.
