Honestly, I couldn't find a funnel to use to transfer recharged desiccant from my oven pan back into the original container, so I modeled one really quick in Fusion and printed it…
Smaller hole outer diameter is 25mm and the larger funnel portion is 138mm
I know it's overkill, but I printed this with four walls, so the only infill was in the little handle, so it is very sturdy.
I've included a 3mf, stl and .step file.
