3D printed ducts for Reptile Cloud-149

Modeled after the original. The original ducts have brass inserts, but I just screwed right into the plastic and it seems to be fine. Requires some work on the screw holes to get going but once the screws grab you can tighten them up pretty good.

These are a fair bit heavier than the original (26 grams vs 10 grams each) but they feel strong.

Update 25/12/2019: added LITE version with slightly thinner wall.

Print with 1.6 wall thickness (4 walls using 0.4 nozzle) and 0% infill for efficient printing. Fast print with these settings. Had some trouble with the screw holes due to travel distance and retraction with combing enabled, recommend turning combing mode off.
