Why This Project?
I sometimes do landmine rows with my coach, Fabien—a great exercise for building back muscles while minimizing lower back strain. Until now, we’ve been jamming one end of the barbell into a corner, wrapped in a cloth to avoid damaging the wall. It worked, but the setup wasn’t ideal and lacked stability.
That’s when I decided to design a simple, 3D-printed anchor to replace the makeshift solution. The idea? A spherical tip that fits onto the end of a 28mm barbell, paired with a wall or corner socket to hold it securely. No more damaged walls, no more wobbly bars—just a clean, functional setup for landmine exercises!
The FreeCAD model is provided.
Printing & Materials
Material: I printed mine in PETG (4 walls, no special settings). PLA should work fine—the forces on the joint are surprisingly low, even with heavy loads.
No supports needed: The design is optimized for easy printing.
Note: If you’re using PLA, consider printing at a slightly higher infill (20-30%) for extra peace of mind, though it’s probably overkill.
Real-World Testing
My coach has used this anchor for dozens of sessions with no signs of weakness. After a week or two, the contact surfaces wore in smoothly, but we noticed a slight squeak. A quick fix: a dab of bar soap on the spherical joint, and it’s been silent ever since!
