Tool Blocks

I always seem to have more tools than places to put them and those pesky hand tools that do not store well in a drawer are the most problematic. So I decided I needed to come up with a tool storage system aimed mostly at those hand tools like pliers, diagonal cutters, strippers, crimpers, etcetera. After multiple iterations here is what works for me, modular tool blocks…

These Tool blocks allow you to configure the storage specific to your needs and also to adjust the configuration over time. The idea is that all the tools you need on your workbench are organized and indexed for quick and convenient access.

The blocks are all the same outside width so that they can be joined together using a pair of small Connectors and form an aesthetically pleasing form to contain your hand tools. The Connectors just slide up into the bottom of the blocks and stay in place with a simple friction fit. The Blocks can then be slid onto the Connectors to join blocks together.

Of course, you select and print only the blocks you need based on the tools you want to store. All blocks are defined by the inside dimensions of the opening in which tools sit.

I have made a bunch of block sizes based on what my needs were. Please send me a message if you would like another block size and I will create it.

I created one open tray with a moveable divider so that I could place things like thread locker and lubricant bottles into it. And, I also created the end tray so that I have somewhere to drop small miscellaneous parts like screws. Of course, all of these are optional based on your needs.


All the parts are straight forward to print except for the connectors. They are printed standing up. To improve their printability I connected them with a small skirt like structure which should break away cleanly after printing.

I have tried to make my main print settings visible on the Cura screenshot but in case they are difficult to read I have summarized them here…


Material: I choose to use PETG for its durability and flexibility.

My Setup:
Nozzle = 0.4mm

My Settings:
Layer height = 0.2mm
Line width = 0.4mm
Wall count = 4 (1.6mm)
Infill = 40%
Ironing = Optional

No support is required.

Print Orientation: As shown in the screenshot(s).

Where to Get My STL Files

I am now posting all of my new designs on and plan to continue to do so for the foreseeable future. Some of my older designs may not have been migrated over yet so if they are not available on please check on Thingiverse.

Use, Licensing, Comments and Feedback

My primary distribution site for my design files is is, in my opinion, leading the way in promoting designers and competition amongst designers which in turn fuels the growth of high-quality 3d printable designs for the benefit of our entire community. However, as a result, some of my designs are only available for free for 1 week from when first posted, so please download them when you see a new file available that you are interested in. Also, please like and save to help me with the competitions.

I do not permit the use of my designs for commercial purposes (i.e. you can not sell my design(s) or products printed from my design(s)) without first acquiring a commercial license from me. On I offer membership accounts for access to all my design files as well as a membership for commercial licensing which allows subscribers to sell printed products using my designs.

I welcome comments and feedback as we as requests for customization of designs. I will do my best to accommodate those requests.
