BBQ Fan Extension for Gearbox 256 In the YouTube clip of my last model, I promised "extensions and applications" for the gearbox 256. With the following parts, you can assemble a large hand-driven BBQ fan. The high impeller speed (2,560 rpm) produces a great amount of airflow. Thanks to the handgrip, it's also much easier to turn the gearbox crank. Parts/Teile Handgrip - 1 Piece 170 x 132 x 20 mm Fan housing - 1 Piece 180.2 x 168.16 x 44 mm 4x M5x12 hexagon socket screw Impeller - 1 Piece 126 x 33 mm Housing top - 1 Piece 180.2 x 168.16 x 3 mm Foot holder - 1 Piece 72.4 x 67.4 x 8 mm - 4x M5x12 hexagon socket screw Foot - 2 Pieces 102.4 x 49.5 x 10 mm Tube adapter - 1 Piece 161.7 x 85.4 x 48.4 mm Corner piece - 1 Piece 78.5 x 12 x 11.5 mm Spacer - 1 Piece 12 x 13 mm The hub includes a clamping function with M4 nuts and grub screws. I noticed during the assembly that the clamping can be implemented easier by variation of the parts dimensions. Don't be confused by the video. It shows that my first printed version of the foot holder needed to be glued to the bottom of the gearbox. The thing files already have an improved screw mount (same for gearbox 256). Add a metal tube to get some distance from the BBQ heat. I glued a 330 mm aluminum tube (ø 30x1 mm) to the adapter. This part needs to be glued to the inside of the tube adapter. I used superglue for all non-releasable connections.
