I worked my way through a few riser variations in PLA stacking them to see what height I thought would work. On that journey I found the source of this remix and liked it's simplicity. I have stretched the model to be taller and adjusted it a bit to ensure everything fits well.

On the riser there is room for two sets of diffusion channel as you can see I did in the photos, but accommodation will need to be made if you are going to relocate the PTFE feed location as I have.

The two gland penetrations at the rear fit a 3/4in NPT ( https://a.co/d/2qm1tP9 ) I use to pass USB cables through to the anker 6 port power supply I have mounted on the rear of the chassis, the other is a PG7 gland ( https://a.co/d/hASihk2 ) I tighten down just enough to hold the PTFE feed in place at an angle that has a more conservative bend radius than stock when the print head is at its two forward extreme calibration positions. This setup allows me to eliminate the previous failure to feed/failure to retract issues I was getting by completely decoupling the PTFE guide from the cable chain and allowing the PTFE to have more breathing room basically.

This riser was part of my preparation to print more high temp engineering materials on my P1S, for that reason the included print profiles were done inclusive of my ASA tuning using the Bambu textured PEI plate and amazon purple glue sticks and Auto brim at a width of 8. It happened to be cold in the room my printer is in so I was running a small ceramic space heater on low to keep the chamber temp from immediately leeching into the surrounding area. With this arrangement I saw 0 warping or lifting. Also of note I was able to get the previous PLA risers I was using to warp while printing this riser in ASA, not a lot but not sure how much longer before it was much more ventilated.

When assembled I also cut rubber footing to go around the bottom where it sits on the printer rim ( https://a.co/d/b4xZZmQ ). Any portions where double sided tape was used I ensured it also had an appropriate temperature range ( https://a.co/d/6on09tj ).
