Turbine Back Roller

The Turbine Back-Roller:

The reason why I took the initiative to start this project was that at O'Dea mainly, there are a lot of back fractures from over usage caused by a build-up of pressure. In order to solve this problem, we needed to figure out a way to release the pressure. Having a stress fracture of my own gave me a lot of perspective when I came to finding a solution. What I would do to make it feel better was to push my back into the back of my chair cracking it. Then we had our solution, but we had to find a way to make cracking your back portable and able to do it by yourself. We revisited the idea of a foam roller and focused on making it able to crack all parts of your back. We redesigned the foam roller to fit in between your shoulder blades and we also added small half-spheres to dig into the muscles lining your spine helping them relax, as a message. After competing my final model I find that it does it job nicely and I use it at home whenever I start to get that hot feeling in my back after sitting to long.

You'll need, Sandpaper, several Hand Clamps, an Exacto Knife, an Industrial-Grade Super Glue, a PLA 3D Printer Filament (Color of your choosing), and of course a 3D Printer.

Using TinkerCad start a new design and drag a doughnut and a half sphere into the bored.

Set the snap grid to 1mm

Size the doughnut 9 length, 9 with, and 3 height

Size the Half Sphere to .75 length, .75 with, and .33 height.

Select the doughnut and set it to these settings:

Radius: 7.37

Wall Thickness: 1.12

Sides: 30

Bevel: 0

Bevel thickness: 1

After, copy and paste several of the half spheres inside of the doughnut.

Once done export as an STL.

Once exported, download the STL onto an SD, plug it into your 3D printer, and size it correctly to fit your margins. insert your color of choice and a thicker print nozzle and print away. It should take less than a day.

Once done printing, pop off the board and mark one side as the first side with a sticker.

Then make a mark on that side 3/4 of an inch down, repeat on every other side, then turn over and repeat on the same sides as before.

After marking the marks around the roller with a sharpie take your exact knife and score the marks and the other side of the half circles.

Finally, use the industrial-grade super glue to stick the half spheres to the roller on the marked spots, be sure to clamp them down to ensure they hold the best.

Once your roller is done drying it's all ready to go. make sure you use it on carpet or turf for the best effect.
