Proper Tool to Measure Diameter

[EMCLOSED]

I 3D print this in Nylon. It is the most accurate way I found to measure diameter. For the record I prefer diameter because it's what we see when we look at a penis. I think of my diameter in terms of intercourse, not my circumference. Circumference is easier to measure with a tape or string. But using this tool I can insert in the various rings until finding the size where I'm touching all the way around. I do not sell this. If you want one then find someone with a 3D printer to make you one.

A piece of non-stretchy string is great for measuring length and girth as well.

I use a 1/2” strip cut from a paper towel and devide by 3.14

Interesting. This is what Kinsey used in the 1940s except it was a paper card he sent to guys to measure their diameters. I like the idea of a diameter measurement. The only problem I see is that the penis is not perfectly circular. The cross section is almost triangular. So the widest part might not fit in a circular hole in such a way that you'd get an accurate measurement.

Have you tried measuring diameter with a caliper and comparing the measurements you get with the sizing tool?

You make me wish I owned a 3-D printer. Are they pretty easy to use?

The problem I envision with that is if your head is larger than your shaft by a fair bit, you'd have to push through, get hard, then get soft again to get it off.

Oh wait, I see you put a ring around your guy and then measure the ring correct?

The non-circular shape of the shaft "rounds up" by the rings pretty well. It feels like a good fit all around.

It can take a bit of wriggling to get past the head.

3D printers are not as easy to use as you might hope. It's more of a project to learn a printer. We use the FormLabs Fuse 1. I have someone here who had to learn how to use it. It's a mid level machine at around $50k for the system. Then the nylon powder is $600 for 6kg, or about 10 cents per gram. That compares to $200k minimum for an industrial system. Most hobbyists use machines that cost around $1000 or less. If you just need a part you can find hundreds of companies who will print your part. I'd suggest you learn CAD first. Fusion 360 has a hobby license that was free and might still be free.
