Finder scope adaptor for Celestron NexStar 8SE

I have a Celestron NexStar 8SE telescope, so my beloved girlfriend design this thing for me, I post this thing here with her permission. Based on ( http://www.thingiverse.com/thing:321295 )

Update: It works really well. if your printer is perfectly calibrated you don't need the screw.

I have other things for my telescope to take a look:

A solar Finder: (be carefull to not look to the sun without a solar filter)
