Mini Chinese Excavator LED Beacon Light

This is a replacement cap for the beacon light of a mini chines excavator. This model has been printed out of PETG (translucent) which has worked well. I opted for rigidity with 2MM outer walls, but it might be a little thick. Model would have to be tested with a yellow translucent PETG filament to see whether the light penetrates better and offers better visibility, to better fulfill its primary purpose. 

Dimensions: 

• Inner thread +/- 97mm 
• Outer thread +/- 95mm 
• Thread pattern M2.5 (2.5MM per rotation)
