Notes:
1 - Send the compressed file contents to the supplier, specifying a transparent background, no holes, and no keychain.

'Polar Alignment Tube' has a maximum triangular parallax error, sufficient for star trackers; 'Polar Alignment Tube - Adjustable Reticle Position' requires separately purchasing an M3x3 screw, printing this version is not recommended unless necessary.
3 - Purchase a red LED and a CR2032 button cell battery.
4 - The front end of the tube has a diameter of 37.7mm, the middle end 28.16mm, and the total length is 180mm. A custom clamping device can be designed.
