Light at the end of tunnel

If you're having a bad day, print one of these to keep you motivated and just know that its not downhill forever! I got a 3rd party tea light that is 35mm in diameter so I could have a pulsing glow and its pretty relaxing and focusing when its on my desk. Bambu lab tea lights should work but its the 3rd plate labeled BL. I used clear PETG for the light holders so it wasn't as bright in the tunnel but you could also just print the tunnel with the hole to let in natural light. I did a multi color track so it could contrast well, but you could change the track to a negative part and duplicate it a little smaller and put it in like a puzzle piece; mix and match as you desire. I glued the PETG case on the back so I could easily change batteries or switch a light. I tried making the light hole slightly larger so the light cap was not too snug or too loose, adjust if you want tighter or wider.

* I did supports, but feel free checking “critical only”; just be mindful the top of the tunnel could sag at certain points
