Stepper Motor z-axis Actuator

thingiverse

**Update 9/26/2017** Added an updated three-point version for the base and the sled to decrease wobbling and a more polished design. ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// A Linear actuator designed to move a glass tube up and down. It readily attaches to a stepper motor face (JAMCO-238538 used in this case). The sled moves along the wooden parts acting as railing. For assembly: **Parts** * 3x Wooden sticks (~8mm diameter, 12mm height) * 2x Base * 1x Lead screw * 1x Stabilizer * 7x Screws (3m) * (Optional) rubber piece for added stability **Tools** * Soldering iron * Hot glue gun In order to open the screw holes on the base, I used a soldering iron to heat the screw and pushed into the plastic. (*This method may cause evolution harmful gases, try it at your own risk, make sure you are in a well-ventilated room and do not inhale the fumes.*). The base and the stabilizer are attached to the wooden railings via hot glue. In action: https://youtu.be/Gc4LbW_UoNE
