Stirrup Ducts
thingiverse
These stirrups are for my previous Thing https://www.thingiverse.com/thing:2538901. 4 M4 x 30mm screws are needed. I printed mine at 70% infill, no adhesion, and supports Touching Bed Only. You will need to rotate each until they lay flat, and the only way to do it is with the tie straps elevated.
