Ender 3 Stackable Tool Holders

Ender 3 top rail tool holders. These are stackable and modular via the dovetails. I designed these to be able to keep stacking on to each other for new purposes or new tools I needed to hang from from the printer for easy access.

I designed them for a tight fit from what my printer is capable of printing. Usually my prints of this size come out around +/-.004 (inch) but you will have to print some test parts to make sure your sizing is correct.

The main body part is what everything stacks upon. To get that correct on sizing I did multiple test parts where I sunk the model through the build plate in Cura to only need to print a small piece to make sure it will fit on the rail.

Once you have the main body, you can attach the others via the dovetail and keep on stacking as far as you wish on whatever end you want. These are the only ones I had the need for at the moment. If you wish, there are optional holes in each part for a #4-40 x 1/8" set screw to help keep the part
