Here's how you can make a holster that will keep your snippers handy and yet be otherwise out of your way.
Step 1: Materials
quick release buckle
long strap or thin scrap of fabric
spray paint that will adhere to plastic
Step 2: Cut the bottle to fit your snippers
Cut away the top and bottom portions, then improvise a curved 'V' shape on one side to allow easy access for your hand.
While you have the hot knife warmed up, cut two slots on either side of the widest part to allow your belt strap to pass through.
Step 3: Spraypaint the holster
Allow to dry completely.
Step 4: Manufacture the strap
Sew it down longways.
Turn it inside out.
Top stitch it along both lengths
Step 5: Attach the buckle
Step 6: Thread the strap through the bottle
Thread the strap through the two slots you made earlier.
