Modular Tool Rail System

This is modular rail system that allows you to organize small tools for easy access. Tool holders of various types slide into the rail. Choose which holders you want based on your tool needs. I have four of these sprinkled around at various workstations and I choose the tool holders based on what tools I need most in that area.

• Update 2022-08-28: Added a holder for a single set of hex keys - the other variants are for two sets. This is an external model. The link is provided below.
• Update 2022-07-07: Added a Nozzle Holder for up to 9 E3D V6 style nozzles
• Update 2022-06-14:
  • Added a large pencil cup
  • Added a two piece version of the original pencil cup.
  • Added a hex key holder with an integrated rail attachment (to complement the one with the magnetic base)
  • Added a tray to hold miscellaneous items
  • Added links to compatible designs by @TickTock and @mortif65. Thank you!
• Update 2021-03-11: Link added to compatible parts by coaster36
• Update 2020-07-29: Link added to a compatible oil bottle holder
• Update 2020-06-13: I added an endcap for the rail
• Update 2020-03-20: I added a holder for a deburring tool. See the table below.

Mounting the rail system
The rail that can be attached using screws through the provided holes to a wall, cabinet, or other surface. You could also use adhesives depending on how permanent you want it to be. I found at least one case where I wanted to mount the unit to a tube (a metal table leg), so I also made a tubular mounting system. There are many variations that could be needed for that including the diameter of the tube and how far the mount should protrude. I provided the STL that I used, but you will probably need to go into the model and change parameters to suite your need.

The Components

Customization and the Model
I have provided a Fusion 360 file with the rail, all the holders, the tube clamp, and various sketches to use as the basis for new components. You can easily add new holders using the components and sketches provided. Also, check the User Parameters (Modify -> Change Parameters) to easily update key settings like the length of the rail.

If you create new components, please let me know and I will link them from here so others can find all the holders that work with this system.

Note: there is a component in the model named "Dovetail Attachment". I provided that s a jumping-off point for holders that you want to be removable, but not mount with magnets. It uses a dovetail mounting system that allows the holder to slide up and off the rail.

Related: If you are using this tool holder, you may be interested in this vise. The original design is really cool and I remixed it to open/close quickly using multi-start threads.

A big thank you to LAY3RWORKS for the design which was the inspiration for this model.

Assembly

Print a rail of the desired length and the holders that you want to go with it. Note that if you want a longer rail than your print bed can accommodate, just print multiple smaller rails and abut them. Or, go back into the F360 model and adjust the RailLength parameter to get any rail size you'd like.

No supports are required for any of the components. They may need to be reoriented when you place them in your slicer to ensure the proper orientation.

If you are printing endcaps and plan to use the screw holes, you should mirror one copy of the endcap in your slicer so the screw holes are both on the top (or both on the bottom).

Once printed, mount the rail to a wall, cabinet or other surface using the provided screw holes or adhesive.

If you are using the endcaps, you can either hold them on using:

• A pressure fit
• Adhesive if you went them to be permanent.
• There is a 3mm screw hole on top. You can use an m3x4mm screw to cinch them into place, or put the cap on and using it as a guide to drill an m3 hole in the top of the rail. Then the screw will attach more affirmatively.

If you are using the tube clamp, you will most likely need to go back into the source model and adjust the relevant parameters to get the size you want:

• Diameter
• AroundDiameter
• Extension
