IKEA Lock Tool Bottle Holder (uses CVS Pharmacy pill bottles)

thingiverse

These are holders for little tool holders that clip on to the side of Ikea Lack end tables. As I printed them, they fit nicely and are quite secure without hardware, but easy to remove if you want to. They have holes for screws to lock them down lighter. One m3x5mm, threaded into the plastic will work- either above the shelf for convenience, or hidden under the shelf for a cleaner look. The bottles are the regular size CVS Pharmacy prescription bottle or a large CVS Pharmacy prescription bottle. ~40mm OD and ~48mm OD respectively below the ridge where the cap attaches. One of each bottle holds lots of tools useful for 3D printing. They need no supports if you orient the models on one side, as long as your printer can accomplish a vertical round hole without supports - as seen in the third photograph.
