Description
The Modular Edge System (MES) is an edge-mounted tool organizer that allows for quick access to your most-used tools. With a variety of modules, you can easily customize your setup to fit your needs. MES will fit against most flat surfaces between 85 and 5 millimeters thick and at least 30 millimeters deep.
I wanted easy access to my tools without them cluttering my workspace. Wall organizers or mounting them next to my 3D printers wasn't ideal. Storing them in a toolbox or drawer risked forgetting their location. I needed a customizable solution for my workflow, tools, and parts, one that could be easily adapted. Unable to find a perfect fit, I created the Modular Edge System (MES) - interlocking tool and parts holders. I've created a few modules featuring rectangular, round, square, and hexagonal holes, along with various sized parts bins.
I've also uploaded a Fusion 360 source file so that you can create your own tool holder modules.
I printed the modules and clamps using PETG but any filament should work. No supports are needed. Make sure that your filament is dry as I had issues with a module that I printed using wet filament not fitting correctly.
The following are design goals that I tried to achieve for this project.
Easy to assemble and disassemble
Be customizable
Be able to hold a wide range of tools
Allow for infinite length of interlocking modules
Print with no supports

Added a screw with an end cap to better stabilize a clamp. Cap easily snaps on and off of the new screw. It also swivels a little.

Added the missing module mount piece to the 85mm Mid Mount Clamp plates in the "Modular Edge System - Clamps.3mf" file.
9/24/2024
Added 85mmx30mm and 85x44mm clamps for thicker table tops.

Added a non-clamping, reduced filament requirements, Mid Mount Support -50mm x 30mm model. Should work for most if not all setups that require mid support.
Added a 60mm clamp screw model (Clamp Screw - 60mm) to support mounting on surfaces now as thin as 4mm.
Mini: End Mount Clamp or Mid Mount Support Clamp > Modules
A single clamp with a couple of attached modules. If you intend to use more than two modules I'd suggest using a Left End and Right End Mount Clamp.
Basic: Left End Mount Clamp > Modules > Right End Mount Clamp
This is the most common setup. If it looks like the modules in the middle are sagging, consider using a Mid Mount Support Clamp.
Mid Mount Support: Left End Clamp > Modules > Mid Mount Support Clamp > Modules > Right End Clamp
Use a Mid Mount Support Clamp if your modules start to sag.
Note: For surfaces less than 15mm thick use the longer 60mm clamp screw.
This is a list of a few organizer modules that I initially created to hold the most commonly used tools. I had to stop or I'd never publish. More will be coming.

The mounting clamps are used to attach the modules to the table's edge. There are four different sizes, 50mm x 30mm, 50mm x 44mm, 85mm x 30mm and 85mm x 44mm. There are three different mount clamp types for each size, left end, right end and mid support. They also have holes in them so that they can hold tools like screwdrivers or Allen wrenches.
Note: For surfaces less than 15mm thick use the longer 60mm clamp screw.
I wanted a semi-permanent way to connect the modules together without having to resort to buying additional hardware (screws, nuts, pins, magnets). Something I could print with no supports and be strong enough to hold the modules together but still be fairly easy to remove. Positioned in a way that it wouldn't fall out. This led to the design of the “L” shaped locking pin.
Because of the tight tolerances with the locking pin hole and variations with filament composition, you may have to adjust the height of the locking pin for the perfect fit.
Instructions
1. Orientation:
|
|
2. Connecting the Module:
| |
3. Locking the Connection:
| |
4. Completing the Connection (Repeat for the Other Side):
|
1. Locate the Release Point Find the square hole on the front of the module where the locking pin is located. | |
2. Insert the Removal Tool Take the Locking Pin Removal Tool and insert its pointed end firmly into the square hole. Push until the removal tool is flush with the module's surface. | |
3. Remove the Pin In most cases, the locking pin should be dislodged by inserting the removal tool and pop out the other side of the module. You should then be able to remove it by hand. If it's held too tightly, then use the “T” indentation located on the top side of the tool to latch onto the locking ping. Wrap your fingers around the T-bar then pull the pin out .
Note: If the locking pin is still not budging after using the Locking Pin Removal Tool then use a 4mm Allen wrench and a hammer to dislodge it. You could tap on the Locking Pin Removal Tool gently but be careful as you may break the tool tip.
