I recently printed this riser for the AMS on my Bambu X1C. I wasn't a huge fan of having to pull the lid totally out each time I wanted to vent the chamber, so I designed these to use instead.

They're print-in-place and the center pole slides in and out, but can't be pushed all the way through in either direction. One side is flattened to better hold the lid.

I printed mine in PETG; I tried a test run in PLA, but the clips didn't have enough flex to easily insert into the HSW on the sides of the riser.
