Massage rollers kit

There are number of massage tools here already but I am not enthusiastic to print something long but thin and I am not enthusiastic to print something that is easier to buy. So I used regular Ø25mm plastic tube as a basis and printed notched sections only.
Number of sections can be chosen for proper massage tool length (the thing on the photo is 25cm working length and 50cm in total) and single section size could be varied as well.
Make a note that the inner radius (Rth) has small addition to compensate thermal shrinkage and allow the section to fit smoothly but tightly onto the tube - you may need to adjust this depending on plastic type and your printing process.

Another thing my wife asked me is (relatively) narrow convex roller. I added two versions: smooth and waved. The same note about inner radius/diameter applies. White tubes length on the photo is 28cm.

And the final thing is a stand for long massage roller, so they could be used together or the long thing could be use
