A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
I can't tell you how many times I've dropped my tablet onto my face when I'm lying down read on it.
But more than that, I had just had enough of the discomfort associated with reading on my device during any stretch of time. There's just no good way to hold the thing—it ends up straining your hands, arms, neck, and back.
I thought there must be a solution out there—a case or grip or stand or something.....but...meh. Not really. I found that most of them are more trouble than they are worth, to be honest.
I just wanted something simple, portable and allowed me to forget that I was reading on a kindle, ipad, or phone.
I couldn't find what I was looking for, so I made it myself.
I used my 3D printer and some design software to test out a bunch of different ways of building a handle—which I then could secure to the back of the device with a suction cup.
It seemed like the proper solution to the challenge I had, so 'Propr' was born.
It works, it's simple, and it does exactly what I want it to do—and I'm guessing it could work for you too!
How Propr works
The device itself is very simple -- 3d-printed plastic with an internal mechanism that pulls the rubber suction cup when twisted.
To 'activate' the handle, simply press the handle on any flat surface, and twist clockwise 90 degrees until it clicks and stops.
To release the handle, simply twist the handle in the reverse direction (counter-clockwise).
Why I am using Kickstarter
I found that this was useful for me, and after talking to friends and family about its usefulness, I was encouraged to raise some funding to put it in the hands of folks who want it as well—and here we are!
Thanks to Chris Zabriskie for the music in the introduction video (Air Hockey Saloon)!
Risks and challenges
The only real challenge that I foresee at this point is that it becomes too popular...
But seriously. Should the demand exceed my capacity for 3d-printing, filament, etc., then I've scoped out a few options for scaling up production by using other printers, and then eventually form-molding, should the need arise.
