My first 3D print for a weird idea

Hi all, polar alignment for me has always been harder than it should be so I use a weird method of laser alignment. To hold it in place I've used tape, blue tac and now a 3D printed bracket.

I found a 3D file on Thingyverse but it had the typical raised legs along the long edge which I filled in very easily with Tinkercad to get the flat base I wanted.

The first attempt didn't work so well when it came off the bed early in the process. The second and third, a spare, were great. So I attached one to the mount and it holds the great little Orion laser holder from Bintel.

Switch it on and align the laser onto Sigma Octantis with the help of binoculars. Then use the laser identified star to position in the polar scope overlay...bazzinga!

I was getting down to 0.13seconds RMS with PHD until recently so got to be happy with that

Cheerio
