Rotary Linear Adjustment Mechanism for Laser (Bosch BT 150 style)

This 3D model represents a rotary–linear adjustment mechanism designed for smooth vertical positioning of a line or point laser, as used in Bosch BT 150–type tripods or compatible setups.

The part converts rotational motion into precise vertical movement, allowing the laser to be raised or lowered smoothly by turning the adjustment section. This enables fine height adjustment without repositioning the entire tripod, which is especially useful for leveling, alignment, and installation work.

Key features:

• combined rotation and linear movement

• smooth and precise height adjustment

• compact, robust design

• suitable as a replacement or DIY upgrade

3D printing recommendations:

• material: PA12 / PETG / ABS

• layer height: 0.2 mm

• infill: 25%

• perimeters: 4 walls
