Adjustable Fan Louver with Rotating Cam Ring · 模型 156447
Adjustable louver for fans with a Ø115 mm air outlet (e.g. 120 mm fans). Turning the outer ring about ±10° tilts the 4 blades up/down by ±45° while keeping them parallel. The ring’s angled cam slots drive a crank pin on each blade. Parts (one set): inner frame, 4 blades (upper and lower blades are mirror images), 4 drive pins (2× 16 mm, 2× 29 mm), rotating ring. Printing: no supports needed; the STL files are already in print orientation. PETG recommended, because the frame flexes slightly while you snap the blades in. Assembly: snap the blades into the frame, slide the ring on until its two studs click into the grooves, then push the drive pins in from outside through the ring slots into the blade cranks. Files: STEP (in assembly position) + STL (in print orientation). No fan mounting holes are included. Attach the frame to the fan as needed. Designed with Claude (AI), verified and printed by me.
