This is a model I made for my bentobox to be secured onto the rods that frame my yoopai enclosure. It has holes slightly smaller than the mounting holes for the voron air duct stl available on the Bentobox model page so you can screw into them , you could also just glue it down or just let it stand as it creates a wider base for the whole model.

If you do plan to put screws in, I'd recommend something =/< m3 x 6 socket caps. Even the 6mm push it because screwing all the way down forces the filament underneath to rupture and break.

I'd also print this in something that a little stronger than pla, OR I'd recommend sliding the (plastic) rod through the hole, instead of trying to “snap” it on. I tried snapping it on and broke the rear clip.
