The project
Collimation is a key step for any Newton or Dobson telescope owner. The standard screws that come with instruments are often impractical — too small, requiring a tool, sometimes abrasive against the mirror support. These 3D-printed collimation knobs solve all of these issues.
Features
- M4 thread, 45mm length — direct replacement for standard screws
- 13mm diameter knob — comfortable grip, hand adjustment without tools
- Rounded ends — prevents punching or deforming the primary mirror support
- PETG printed — resistant to repeated handling in the field
Installation
The replacement is direct: unscrew the original screws and replace them with the knobs. No tools needed for installation or use. Perfect for observation nights in real conditions.
