Crayford focuser 2" - 3D printed

[Chriske]

Hi all,

Did not want to hijack AdeKing's thread so I started a new one on that Crayford focuser I mentioned before.
This focuser will hold 2" eyepieces.  It performs very well,  it has a reduction ratio of 6:1 and it's action is very smooth.
The focuser barrel has no flat,  there's no need for it. Pressure of the focusing-rod onto the focuser-barrel is adjustable.
The focusing unit has a flat base so depending on the scope's diameter you need another part to fit the scope.
There are two versions of this focuser, a longer one to allow a stepper, and a shorter one. I did not add the stepper myself yet.

Total cost of this thing : a whopping 16€. That includes the dual speed knob and the(6)ball bearings.
The two pushbuttons are not included, in this case they're there to activate two boundary-layers-fans for the primary and the second(green) button is for the laser pointer.

Wow, love it. ....these 3D printers are superb, and you guys that use them....I have loads of ideas for using a 3D printer for Astro kit, but alas due to moving house funds will not allow to purchase one yet...
