Big Button

This is a 3D printed joystick handle for electric wheelchairs.  We call this shape the Big Button.  The handle is approximately 2 7/8" (72mm) wide, and 1" (25mm) tall.  Included in the purchase are one Big Button handle and one allen wrench for the set screw.
 The Big Button is intended to replace a missing knob, or perhaps is better suited for the user.  This handle was created to fill a need.  Some people lack the dexterity to control their chair in its stock setup and may find this shape allows better control.  
 We currently have many colors available as listed.  Most chairs come with either a 3/16" or 1/4" diameter joystick shaft.  You'll need to verify which one you have before ordering.  The knob you receive will include a small allen wrench.  Use the wrench to "lightly" tighten the two set screws (across from each other) near the base of the handle (overtightening will strip the threads).  The set screws won't completely prevent the knob from turning but should prevent accidentally knocking it off.
Please check our store for additional handle shapes. we welcome suggestions for shapes as we would like to grow the inventory.  Each handle is custom printed per your order, so please allow a couple of days for processing.
