Last crawled date: 4 years, 1 month ago
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.
