Collapsible focuser 2" - 3D-printed

[Chriske]

Hi,

Somewhere in another thread I mentioned a second focuser I designed. This is that other design.  Drawings are made using Autodesk-Inventor.
This one is a real low profile focuser because in its lowest position the eyepiece-barrel will enter the telescope tube by a few mm. I have two versions of this collapsible focuser.
Like the Crayford this one also works very smooth. It has a travel of about 85mm(3"+)

Hope you like it...
