I printed and very much like the AMS riser https://www.printables.com/model/535282-v2-update-bambu-lab-ultimate-p1p-x1-c-riserams-sta but it had an issue where the PTFE tube going to the toolhead would catch on the riser when the toolhead was on the far right side of the build plate. The extra bending didn't seem like a great idea so I made this wedge to guide the PTFE ‘under’ the riser. It's super glued in place.

I printed it in PTFE because I also print high temp materials, I may need to reprint it in ASA if it doesn't hold up!

It turns out it also makes a nice multi-position prop for the glass top and depending on how you orient it you can change how high the front edge is lifted. When you use it to prop up the lid, place it so that the screws that hold the lid's handle are in front of the guide—that keeps it nice and stable. Do note that I have put window weather stripping on my riser to help seal the glass, it also helps keep the prop from slipping.
