Custom Multi Tool Case

Hi, my name is Jeff and I am a Maker.

When I started volunteering in my local Library's Maker Space, I was influenced by the new technology to design and make new things.

I had been wanting to build a replacement for the leather case I used for over 20 years to hold my Multi Tool. It sat uncomfortably high on my belt, didn't show off the Multi Tool and was not easily removed or inserted. And when I saw Adam Savages one day build of his custom metal case I was inspired to create my own design.

I designed and made my custom case using the resources at my local Library's maker Space.

For this project you will need access to:

- Multi Tool

- 3D Scanner

-TinkerCad (Free Online Design Software)

-3D Printer

-Hand Tools

The final step has a build video of my process. Please follow and subscribe to see all my design.

Step 1: 3D Scan the Multi Tool

I covered my multi Tool with painters tape. My tool was stainless steel, so the 3D scanners laser would reflect without the tape. It takes 9 minutes to scan the object.

Our local library has a 3D scanner accessible to the community for free. It is straight forward to use, following the step by step instructions on the screen. (But if anyone is interested I can create a Instructable on how I 3D scan objects.)

I want the 3D Mesh Model of my Multi Tool to build a custom case around it using TinkerCad.

Step 2: Design in TinkerCad

Import the 3D scan into TinkerCad, a free online 3D Design Software.

If there is interest I can create a Instructable on how to use TinkerCad but their website has tutorials for new users. The software is very easy to learn and I volunteer at our Maker Space teaching, kids 5 years old up to retirees, how to 3D Design with this software.

The video at the end of this Instructable has a spoken tutorial on the process below:

- Use the software's blocks to build a case around the scan. I didn't take any measurements, and eyed the size and shape that looked and felt right for me.

- Use the hole tool on the scan to hollow out the case for an exact fit for the tool.

- I created a slot in the front so the tool can be easily removed with one finger.

- I wanted a maker theme so I used the software's text tools to add this. I turned the text on the sides to holes so the tool will show through.

- Use blocks and holes to create a loop for the belt to go through.

- I added holes in the back to tweak the design to how I waned it to look.

Step 3: 3D Print the Case

Our local Library has a 3D printer that is free and accessible to the public. Check what is available in your community or use an online 3D Printer service to print out your design.

I printed in standard resolution, 10% infill, with raft and supports. This printer used PLA filament and had a wide selection of colour choices. The print took 3 hours.

Once completed I used needle nose pliers, small file, dental pick and hobby knife to remove support material.

Step 4: Insert the Multi Tool in Its New Case

I love the new Maker Theme look over the old traditional leather case.

The multi tool snaps into place in the new 3D printed case.

In future designs I would tweak it so the belt loop has some rotation but as a first draft the project was a success.

I have included a build video of my design process. My Build Video

Thanks for the interest in my Custom Multi Tool Case.

Cheers, Jeff

    I was going to mention Adam's metal work one too.

    I worked at a library for 7 years and it would have been cool if they set up a maker space but I think they wouldn't have gone for it. Is it in an unused area or what?

    Public libraries are "adapting" to meet the needs of the community. More and more libraries are setting up Maker Spaces. Ours has been open for 2 years, with a designated room built on the exciting library's foot print. It wasn't a large area, but it had a workbench, raspberry pi, arduino, little bits, egg-bot, 2 mac workstations loaded with video, music, photo, and modelling software used for creativity, a 3D scanner, 3D printer, and green screen, lighting, mics, cameras for video production. If you build it they will come as they say. The Maker Space and Maker community has grown and developed into a continuing evolving culture. Young kids up to seniors citizens are using the new technology that would otherwise not be accessible to them. People are using it for fun, education, work, school and hobbies. Its also developing into a hub for creative networks of various skill and knowledge being shared between users in the community. Ours was created from the support of dedicated library staff and financial support of a local foundation. It is now actually closed for renovations, going through a hugh expansion of space, and addition of new work benches and computer stations, cnc machine and laser cutter, and will be finically supported ongoing by corporate industry sponsors in the community.

    shizumadrive you should definitely advocate your library to set up a Maker Space. do a google search on "Maker Spaces & Libraries" and read of others experiences of setting up Maker Spaces in Public Libraries. Be sure to update me if anything comes of it.

    I see I am not the only fan here on Instructables of Adam's work. I gave him a shout out in both my tutorial and video for the inspiration. How amazing would it be to get his feedback on my approach and design of a custom multi tool case. :)

    cheers, Jeff.

    Very nice! Without reading a word, my first thoughts were "Looks a lot like Adam Savage's."

    It's a great design, and perfect for 3D printing. Excellent stuff, thank you for sharing this!

    Thanks seamster. I love all of Adam Savage's builds. And so jealous of his workshop. It is my dream to have a place like that some day. Would love to meet Adam some day.

    Thank you 3366carlos. I was very proud of that design and how the 3D scanning & printing technology produced a prototype that fit like a glove. It is an amazing time for creating.
