Height Adjustable Bar Stool cnc

thingiverse

This height-adjustable bar stool is the culmination of my search for a chair suitable for use at both my computer and CNC machine in the shop. Both surfaces are significantly higher than any standard desktop, necessitating a bar stool with adjustable height. Since I was unsure of the exact required height, I developed a simple method to adjust the seat: by tilting it slightly and inserting it into the corresponding recess, it will fit snugly into the curved "ladder" of the legs. After several iterations of CAD modeling, I conducted initial test cuts on the CNC machine. Further refinements and a full-fledged prototype constructed from inexpensive pine wood revealed that the concept was generally viable, but the soft wood suffered excessive bending under the seat and backrest. A friend's prototype built from Baltic birch plywood proved highly successful. Unlike many of my designs, I employed screws and tenons to join the parts together. To facilitate predrilling with the CNC machine, I added markings to the drawing. Following assembly, I drilled holes into the corresponding counterparts.
