Introduction: Carabiner Cup
If you are a camper, hiker, mountain biker, ATV'er or snowmobiler, you will recognize the need for a cup like this. It easily clips to your belt loop, backpack or any part of your bike or other machinery. Also, it only takes about 10 minutes to make and you may already have everything you need at home.
Step 1: Gather Your Stuff
You will need a sturdy, non breakable plastic mug, the kind that you can wash and re-use. Also a carabiner sized to the mug and some epoxy glue. Bonus if you find a mug with no handle. A hack saw and file will come in handy too.
Step 2: Remove the Handle (Or Not)
I used a band saw to cleanly cut off the handle close to the surface of the cup. A fine tooth hacksaw can also be used, or a Dremel with a cutting disc. File or sand any plastic nubs that remain to give a smooth surface. The carabiner will be your new handle as well as attachment device. However, if you choose not to remove the handle just attach the carabiner to the opposite side and skip this step.
Step 3: Prepare the Carabiner
Clamp the carabiner in a vice or vice grip and file the surface opposite the clip. This will create a flat glueing surface.
Mix the epoxy according to manufacturer's instructions and apply to the filed carabiner surface and to the cup in a line where the old handle was. Check to see that the two surfaces mate up with no gaps first. If not file or sand till they do. Press the parts together and tape in place till dry. Adjust while the glue is still tacky to make sure you have perfect alignment. While most epoxy dries in 5 minutes, I'd wait 12 hours before I'd trust it to hold liquid, especially hot liquid.
We have a be nice policy.
