The pouch and clip are rather expensive to buy, the lady who the item was for was happy to sew her own pouch but needed a quick way to make the plastic part that clips on to a bra strap
The cloth pouch is worn under the clothing and holds a device which is about the size of a mobile phone.
Step 1: Collect materials and tools
A sheet of plastic, I've used ABS 2.5 mm thick (polycarbonate would also be suitable)
A scalpel or craft knife
straight edge or rule
a vice or clamps
a few bits of metal plate or wood to act as heat shields and/or bending jigs
Hot air gun
Wet and dry paper
Step 2: Cut the plastic
In this case I've cut my strip to 10mm in width to copy the original clip.
Take care with the scalpel!!!
Scalpels were designed to cut flesh, guess what they are really good at cutting.....?
Step 3: Clamp the plastic
you're going to do the smaller bend first that's the one on the inside of the clip.
Make sure you have clamped the plastic square (at a right angle) to the metal that's holding it.
