This is a riser intended for the Comgrow Filament Dryer Box PN: AK36WG-1200400J. I did not like how the PSU was separate from the dryer box and how much waste heat was being thrown off of it never to be utilized by the dryer box. Of course this isn't going to significantly impact efficiency in any way but it helps organize the cables and PSU, so why not.

I printed it is PET-G just to be safe, but you can try your hand at PLA at your own discretion. I did find that for my printer (Bambu Labs A1 Mini) with PET-G, I had to enable “Avoid Crossing Walls” since the Hexagons are fairly thin and any PET-G still hanging on the nozzle can knock over them before they are complete.

Sorry for no .3mf upload, but I use Orca Slicer. If you would like the .3mf for that you can find this same model at https://www.printables.com/model/689654-comgrow-filament-dryer-riser-v1.
