Yes, something like that. I would like to see one with a closed top, rounded, and have the magnet inside so it completely covers the button and holds securely in place. There is also the possibility to make the cap into a dual purpose accessory and it could turn into a scoop or hide a small amount of herb or something......
Yes the magnet is in the charger but there may also be one in the on/off/temp assembly as well because I feel a little magnetic pull when I unscrew the dial and change the batteries. Metal would work but it needs to be insulated because the metal cannot connect the button to the dial part or it can potentially turn the unit on....I thought someone mentioned they tried connecting the two metal parts of the GH together with a quarter and it turned the unit on, a few pages back
Here are a few picks of the Pack-N-Stash funnel. It holds securely in place so you can just put your herb on the funnel and slowly shovel it in and see whats going on to get the perfect fill with no mess. I would still like to see a scoop though and I am trying to make one but so far, the funnel works great.
