Introduction: Quick Electric Sit-to-Stand Desk
Sitting at a desk all day can lead to poor posture, health problems, and back pain. Unfortunately, electric sitting/standing desks are expensive. So, I decided to build my own!
Step 1: Mounting Plates
With four linear actuators from eBay, I started by sketching the layout in Autodesk Inventor, found some appropriately wide scrap in the yard at the TechShop, and fabricated bracket blanks.
Step 2: Drilling Mounting Pattern
I wanted the brackets to be useful in a variety of ways, so I designed the layout carefully to allow for mounting at a variety of angles. Wrote a bit of G-code and drilled out the patterns on the Tormach CNC mill.
Step 3: Table Frame
Used some leftover 80/20 aluminum extrusion to bolt together a quick table frame, then added the actuators using bolts and t-slot nuts.
Step 4: Wire the Motor Controller
I got a four port controller to go with the legs. It keeps them in sync and prevents the table from getting misaligned or wrenched.
Unfortunately, I didn't check the motor travel of the linear actuators closely when I purchased them and they didn't lift high enough for me to stand comfortably. TechShop to the rescue! I purchased a set of furniture risers and using the mill, drilled holes to match the mounting holes on the bottom of the legs.
Step 6: Risers Attached
Bolted the risers to the legs.
Step 7: Stand and Deliver!
We have a be nice policy.
