I saw Creativeman
's duct tape dispenser and it inspired me to make this one. I decided to make mine have more than one function.
Step 1: Tool and Materials
1/4th inch drill bit
hack saw or metal cutting blade on miter saw
1/4th inch threaded rod (I had some left over from refurbishing a swing set)
2 AA batteries
Packing tape dispenser
Step 2: Assembling the roller
I cut a piece of straw the width of a the duct tape. I put a nut on the rod. Then I drilled a hole in a soda bottle cap and threaded that onto the rod. Then I put the straw onto the rod. I placed another nut on the other side of the rod. A washer simulated the body of the flashlight. Finally a washer and a nut secured the end. I cut the threaded rod after attaching everything to make sure I had enough rod. You can leave a little extra just in case. As your last step select some duct tape to roll onto the straw.
Your results might be different if you use a different flashlight. Mine is a Stanley.
Step 3: Installing the dispenser in the flashlight
Drill a hole in the bottom flashlight using the 1/4th inch bit. Then remove the spring at the bottom. Took off the end nut and washer and set them aside. Then I dropped the rest of the roller assembly into the flashlight with the bottle cap pointing up. Using my finger I held the threaded rod still while I screwed the flashlight onto it. Then I put on the washer and nut on the exposed rod. If you are worried about the exposed metal just cover it with duct tape.
Now you will want to cut a hole in the side so you can get to the duct tape. Using your utility knife cut a rectangular hole 1/8th an inch wide and 2 1/2 inches long.
