First-time QHYCFW filter wheel user here. I created an OpenSCAD script to auto-gen the filter cover for filter installation.

 

The OpenSCAD script is designed/implemented for generating 3D printable models for QHYCFW3 filter wheel filter masks to make installing unmounted filters much easier. User could change the following parameter (please check with official QHYCCD CFW3 filter wheel drawings: https://www.qhyccd.com/qhycfw3/). The filter covers make filter installation to QHYCFW3 very easy - It helps to center the filters, avoid light leaks and secures the installation. It's a much better solution than the factory M.2 screws + M.2 washers.

 

Please note, this design is for unmounted filters with thickness of 3mm. - For example, Chroma/Astrodon unmounted 31mm filters, unmounted 50mm round filters and Antlia unmounted 50mm round filters. If the filter thickness is 2mm or below, this solution is not feasible.

 

I printed mine at a local library, the cost is 30 cents in this highly inflated world.

 

Currently, the following CFW3 filter wheels are supported. The square filter version is not available in current version.

  • QHYCFW3-S-SR 7x31mm
  • QHYCFW3-S-SR 6x36mm
  • QHYCFW3-S-US 7x31mm
  • QHYCFW3-S-US 6x36mm
  • QHYCFW3-M-SR 8x31mm
  • QHYCFW3-M-SR 7x36mm
  • QHYCFW3-M-SR 5x50mm
  • QHYCFW3-M-US 8x31mm
  • QHYCFW3-M-US 7x36mm
  • QHYCFW3-M-US 5x50mm
  • QHYCFW3-L 7x50mm
  • QHYCFW3-XL 9x50mm
