I needed a part, so I made a part.  Plus, waiting 3-4 weeks for the factory direct Creality riser set to arrive didn't sit well with me.  So I designed this variable set to use with the rotary centering device I found that was designed by Bad Appleseed (Creality Falcon2 22W Laser Rotary Pro Markers Remixed by Bad Appleseed - MakerWorld), which was based on the Creality Falcon 2 Rotary Pro tool (Creality Falcon 2 Rotary Pro tool by dustabuster - Thingiverse) by "dustabusta".  Didn't change either of their designs, I just made these leg extensions to work with them.  So far so good.  been using them with success for two weeks.  Oh, the factory risers came…they're still in the box.  Oh…I used PETG.
