This funnel/lid allows for easy, no mess re-filling of the DryBox desiccant container. I built this because I was not skilled enough to pour my dried pellets into the small opening of the dry box open-ended version without spilling them everywhere. Made this in a half hour or so in Blender 3d by starting with the original lid and modifying it. First print of this looks good and works flawlessly.
Note: the threads on my print (in silk PLA) were pretty tight but usable on the first try. I did use the tighten/loosen/tighten approach so slowly break the threads in the first time and keep from them getting too tight as the fine hairs broke up. After a couple tight/loose cycles per centimeter or so the threads loosened up nicely. So if it starts to get too tight, just back off and work it a little to get them free again.
When you get near the bottom of the threads the inner stop should hit the top of the container and seal it so beads won't leak through while pouring.
Blender 3d Used to edit Lid and extend
- imported the existing dry box open ended lid
- used duplicate verts to position 8 cylinders on the lid
- used boolean operators to cut holes in lid
- added cones for funnel shape and hole cap
