pinshape

Summary Save your pliers for camping trips by using this device instead to operate your broken gas stove. I've even used it as a volume control knob with great results. Instructions Set the parameters in OpenSCAD according to your needs. Print out the design and you're good to go. If necessary, secure the knob onto the shaft by placing an M3 nut in the nut trap and sliding the holding M3 bolt through the hole before tightening it snugly. Remember when setting variables: The "flat" parameter refers to the flat surface that slides onto the shaft and is measured as a percentage of the shaft's diameter (e.g. 0.5 for half or set to 0 if not required).
