Attach a screw cap to the top of your coffee bag so you can quickly access your coffee. The pour is easier to control with the smaller width hole.
Print one of each of the following...
CoffeebagCap or CoffeeBagCap2
Open your coffee bag and hold the CoffeeBagLid in place at the top of the bag so that there's enough of the bag for the CoffeeBagClip to hold. While holding the CoffeeBagLid in place with one hand, pry open the "tongs" of the CoffeeBagClip with the other hand and slide it over the CoffeeBagLid. The lid should now be loosely held in place. Slide on the CoffeeBagLock to lock the clip into place. Screw on the CoffeeBagCap!
It's not the easiest thing to attach, but when it's on it's secure. If anyone has any good ideas to improve the attach process then please let me know.
