I have an idea

[Frodo]

I have an idea, wanna kick it around and see if we can figure it out?

 

a pvc pipe, open back bangle, covered in leather

with a strap to hold a watch.

Man, you are the creative one, aren't you? Brilliant idea, my friend! I'm no help here though...

Just in case it helps some. As you would have found out I think it can be difficult to sand around the edges whilst its round. What I found in the end to be quicker and to get the more oval wrist shape is to cut the pipe into lengths to get the width then cut into the side (65mm pvc vent pipe I think) I then procede to heat them up with a hot air gun and flatten them right out straight and allow them to cool of under a flat slab. They are then easy to shape and chamfer etc. I found a piece of steel pipe and based into an oval shape and from there I heat the pvc pipe again and bring it into shape. After that I attach foam and leather and lining etc. Now its easier to just 3d print them in pla. I have not done the watch band as such but here is the open back bangle shape. I think the weight of the watch may just beat you on this but you'll never know lessen ya try  Might be able to mix the ideas a bit

With all that work wouldn't it be better, more cost effective, using kydex or other perhaps cheaper thermoplastics? Or would that still be too expensive?

Once the drawing file is done and from a stl file into the G code, its pretty much turn the printer on and go on working on other stuff. I do have a plastic extruder that took a LOT of work time to lathe up the moulds for these bangles and they are quicker to do in time but maybe not in the labour cost. BTW if you get into the 3d print stuff the hangers holding the bangles in the third picture are something I came up with to make it easier to get an individual bangle or bag on and off without taking off a whole lot.

Here you can see if you want to get to a bag on the inside you have to remove all the outer ones first.

I had to come up with a something to put in a shop so this was my answer.

Good stuff, but for us without 3D printers I think maybe thermoplastics could work. I've wanted to get into 3D printing for a while though so who knows what the future brings...

Looks good. Thanks.

And if it's a UK company I'll probably be able to get it for less than half price some time after October....

 

Sorry, just kidding... I hope...
