Squeeze Fan - POCKET SIZE

If gears are stuck, it might be caused by stringing or seam alignment(use random seam for best results), which can leave a ridge that causes jams. To ensure smoother operation, perform post-processing such as sanding down the shafts and lubricating them if needed. Indroduction This is a fully 3D-printable hand fan powered by a crank mechanism. By repeatedly squeezing the handle, a connecting rod transforms linear motion into rotary motion, spinning the propeller at the front. The propeller securely mounts onto the shaft using a locking feature combined with a ball snap fit, and it’s available in both clockwise (CW) and counterclockwise (CCW) variants. (i recommend printing CW propeller) . Everything is 3D-Printed The model is divided into individual parts that are optimized for easy printing with minimum supports. All components are designed for snap-fit , press-fit assembly or screw in place, and glue is optional for added strength. Every connection type—whether snap-fit, press-fit, or screw—is clearly indicated in the Assembly of the included instructions. Chose right files: You can print part individually or fully on build plateRecommended print and matterial settings: Material: PETG,ABS (PLA can be used also but i dont reccomend it ) Infill and wall count : Gears: 20-30% infill , 2 walls (Gear 4 needs support) Cases: 30-40% infill, 2-4walls (mine worked best at 4 walls) Upper case needs supports in screw conpartment Press Fit Shaft : 100% infill Propeller : 100% , infill Supports ON (Can be printed without supports also) Other: 20-30% infill Use random seam for best results on the shafts Layer height: 0.2 mm Lubrication : I recommend lubricate the gears and shaft for smoother , quieter and longer operation , you can use vaseline , silicone oil, … (i tried it without lubrication and it worked ) Print orientation is optimized for minimal post-processing.
