Assorted CNC tool adapters for 65mm mounts

I made these tool mounts for convenience on CNC's that use a 65mm diameter spindle mount. Left to right in the first photo, a Roland style dragknife, a 2.5W diode laser, a 40W Neje diode laser, and a router table stand.

The STL files are named accordingly. The dragknife is a 2-part assembly, using M3 bolts and nuts and some zip ties. The v2 holder has slightly stiffer and wider suspension arms; either version will work best in PLA.

I also uploaded my air assist nozzle design for the 2.5W laser, in case you don't already have a good one. I was inspired by djk4linux@mpcnc forums excellent Neje nozzle design, and made this along the same lines. The air hose hole is slightly undersized to be drilled after printing with a 1/4" bit. The mount for the 2.5W laser also has an upper hole to help secure the air hose so it doesn't mess with focus.

Notes:
I decided to put the bottom flange on the Neje adapter because this laser is very powerful and can produce a lot of smoke. Without the
