Tell us about yourself!
I would say it's a challenging project especially since it's variable based on body type and measurements. I finished mine in 30 days, but those were some long days. Starting the project is probably the most difficult. Once all the things start coming together, it moves quickly. Hope that helps.
Here is the tape file. The measurements of it would depend on your own measurements.
This should be it.
They had a strap on the top part that on the other end had velcro so that I could thread it around a belt on my waist. I hope that helps you out.
I just measured off myself and visually tried to make it to scale. No template as far as I know.
