Heat Shrink Tubing without a Heat Gun or Flame

Hi Guys,

When I was researching and designing my lanyard kit I wanted to develop a way for people to use heat shrink tubing without investing in a heat gun.  You can use a lighter or torch but you risk burning the tubing.

 

    I searched online and couldn't find anybody using a home oven, but I found a bunch of commercial heat shrink tubing ovens.  I started experimenting. 

    After some testing I determined that 250F in a home oven for 5 minutes works great!

Here's some heat shrink I was just working on!
