Introduction: Modular Fascia Roller
You can buy many different types of fascia rollers to treat sore muscles after injury or sports. Most of them are good to treat a select few types of muscles due to their design. Some of them are heavy and some take up so much space that you don't pack them in your suitcase.
My design can be customized to be your perfect tool. You get a fascia tool that is modular, very light and small enough to pack into your luggage or gym bag. And all this for very little money.
What you'll need:
- a piece of PVC electrical pipe (or similar) - I used 25mm outer diameter pipe, but you can always scale your print
- a saw to cut the pipe
- some sandpaper to finish the edges
- access to a 3D printer - most towns have hacker-spaces or 3D printing services available
Step 1: The Pipe
I used a 25mm outer diameter electrical PVC pipe for the axle. If your country uses different PVC pipes, just scale the print accordingly (x,y). Trim the pipe after you've tested which pieces and how many of them you want on your roller. Begin with a long piece, you can always make it shorter.
Use sandpaper or a file to make the edges smooth.
Step 2: 3D Printing
Now it's time to select which pieces you want on your roller:
All the files are on thingiverse: https://www.thingiverse.com/thing:2894742
The end caps (2x) should have a very snug fit. Make a few test prints and scale them (x,y) if they don't fit. If you are only a bit off you can use a hair dryer to heat them a bit and put them on the pipe. The roller parts have an inner diameter of 26mm, so they are meant to move freely. Choose and try the different designs.
If your PVC pipe has a different outer diameter:
Let's assume your PVC pipe is 30mm wide. My PVC pipe is 25mm wide.
(30mm/25mm)*100% = 120%
This is the scaling factor that you have to use in Cura (or your preferred slicer) for all the pieces for the x,y axis. Unselect "Uniform Scaling" and fill in the values. [see picture of Cura slicer]
Step 3: How to Use
I won't go into details about trigger points and how to treat them. There are many opinions out there which technique is the best and I'm really not an expert. Google at will, you'll find plenty information.
My personal favourite is the flat_3elements roller with the smooth_large wheel on the side. This lets you roll your calfs and the wheel can be used to apply pressure to sore spots that are a bit deeper in the tissue. Hold the roller as shown in the picture and you can perfectly adjust the pressure by applying force to the handle that is on the opposite side of the big wheel. If your legs are a bit wider, use several of the flat_small elements or scale the flat_3elements in the z direction.
