Low back pain is never fun, and in my quest to relieve it I found several "psoas release" devices online. Rather than spend my hard-earned coin on an injection molded pair of humps, I searched for 3D printable versions, only to come up dissatisfied. Some were lightweight but had print issues. Others were strong but filament hungry. So I decided to make my own.
This model was inspired by other tool designs, albeit with the goal of maximizing strength while optimizing filament use. I wanted to take advantage of inverse catenary geometry to build a structure that was naturally strong at the peaks. The model approximates that geometry by using ellipsoids for the main structures.
There are three models; I recommend printing "Infill, no shell" if you just want to use the tool. The others are design variations that may be interesting.
Standard PLA has more than enough strength for this model. The example shown above was printed in Prusament Galaxy Purple PLA, and is strong and light.
Recommended Settings:
Print the "Infill, no shell" model
Infill: Gyroid, 5%
Four (4) perimeters
Two (2) is probably fine. I printed with four (4).
0.2 mm layer height (default).
Thicker layers will likely work just as well.
No need to print any thinner!
Automatic supports under the arches
No other modifiers, brim, etc. needed.
My question is: Is this design any better than the others? Does it do the job better? Is it easier to print?
