Improved holder for TwoTrees Laser "Focus Assist Metal Column" v1.0 — TTS-25 (2.5W), TTS-55 (5.5W), TTS-10 Diode

With certain models of TwoTrees diode laser rigs, including TTS-25 (2.5W), TTS-55 (5.5W), TTS-10, a 3D-printed holder comes with it, that holds the nice “Focus Assist Metal Column.” In my case the hole was too small (too tight for the holder to fit down in it), and so when I went to create a model for a re-design of my own to print, I decided to not only give it a finger-sized hole in the bottom to push up the metal focus column, but also have that hole be part of a “slot” so the finger lifting could then sweep all the way up. I consider it a minor improvement, basically a nice “ease of life” improvement.

Air Assist Note: Whenever you order and use the TwoTrees air assist pump and accessories, it requires a shorter “Focus Assist Metal Column” which they provide in the kit. This print also works for that shorter, anodized black column for when using their air assist kit.  Works with the shorter column pointed either up or down. I printed two of these, and mounted one in the normal place (left of the control board, using the existing screw holes), and another opposite of it on the right side of the control board, using two of the little spinning hammer nuts. I had some M4 hammer nuts, and used two M4 x 12mm screws to attach to those.

I am including the STL and the Fusion 360 file of my design work.

Print notes:

• Print as oriented.
• Needs no supports.
• I printed at standard quality, 0.2 mm layer height, using black PLA.
