We have a couple of robot vacuum cleaners, so my wife always puts the bar stools up on the kitchen bench to allow them to clean under there.
I first tried installing some brackets under the bench to hang the stools slightly off the floor. However, you hit them with you knees when sitting at the bench. So In decided to make the brackets swing up out of the way when not in use. These work well.
Note: the basic design only allows both brackets to swing to the left only, unless you later round the top of the bracket off on the other side. This made them easier to print with no supports.
To install them, essentially you have to mount the brackets in the retracted position (as shown in the last photo). First take one bracket and install the link in place (refer to the pictures). Install the mount into the bracket and screw it to the underside of the bench, ensuring that the bracket is pushed up against the back wall of the bench which helps to stop the link from working its way out. Then take the bracket you just installed and swing it up against the bench underside. Attach the other bracket to the other end of the link in the retracted position also, then (ensuring both brackets are swung tight to the underside of the bench), screw on the second mount.
Mounting them in the retracted position ensures that the mounts are spaced the correct distance apart. If not, they will bind up as you try to swing them up.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more.
