BBQ Fan Extension for Gearbox 256 In my last YouTube clip, I promised "extensions and applications" for the gearbox 256 (check: www.thingiverse.com/thing:2805140). 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: 1. Handgrip - 1 Piece - Dimensions: 170 x 132 x 20 mm - Includes: 2x M5x12 hexagon socket screw 2. Fan housing - 1 Piece - Dimensions: 180.2 x 168.16 x 44 mm - Includes: 4x M5x12 hexagon socket screw 3. Impeller - 1 Piece - Dimensions: 126 x 33 mm - The hub includes a clamping function with M4 nuts and grub screws. 4. Housing top - 1 Piece - Dimensions: 180.2 x 168.16 x 3 mm - Also includes a clamping function by variation of the parts dimensions. 5. Foot holder - 1 Piece - Dimensions: 72.4 x 67.4 x 8 mm - Includes 4x M5x12 hexagon socket screw 6. Foot - 2 Pieces - Dimensions: 102.4 x 49.5 x 10 mm - Those parts still need to be glued to the foot holder. 7. Tube adapter - 1 Piece - Dimensions: 161.7 x 85.4 x 48.4 mm - Add a metal tube to get some distance to the BBQ Heat. 8. Corner piece - 1 Piece - Dimensions: 78.5 x 12 x 11.5 mm - This part needs to be glued to the inside of the tube adapter. 9.
