Adjustable 3D-Printed TV Arm Mount

A fully 3D-printed TV arm mount that allows you to pull your TV away from the wall and rotate it freely in multiple directions. Designed for strength, stiffness, and practicality — perfect for custom setups or compact spaces.

The model includes slots for cable ties, so you can route your cables neatly through the arm.
If the joints move too smoothly, use the included printed rings as spacers between the rotation points — this increases friction and keeps your TV in position.

When the TV is not in use, make sure the arm is folded in against the wall to prevent long-term creep in the plastic.

choose the material witch you think is best for your situation!!.
