Introduction: Wooden OP-1 Case

Expensive gadgets deserve to be protected. One of my musician friends from a band called My Son Bison has an expensive synthesizer called the OP-1 and wanted a case to protect it while on tour. This custom OP-1 case was designed using Fusion 360 and 123D Make and cut on the laser cutter and router table. The two halves of the case are attached to one another using strong magnets glued into each side.

For this project you will need 1 24 by 36 inch piece of 1/8 inch plywood, wood glue, epoxy, four 1/4 inch diameter cylindrical neodymium magnets and some wood finish.

A similar process could be used for any similar electronic device.

Step 1: CAD Design

I used Autodesk's Fusion 360 for the design of this case. The first step was to accurately model the OP-1 it's self. I used calipers to measure each component of the case and entered the dimensions into Fusion. Next, I used the boolean functions in Fusion to create the case.

Step 2: Slice

123D Make is a very simple software for slicing a 3D model into stacked layers. I chose to use 1/8 inch plywood for the case, so it required four layers for the top and four for the bottom. I took the file exported by 123D and used Adobe Illustrator to clean up the lines for laser cutting.

Step 3: Cut

A laser cutter is a great tool if you have access to one. If not I suggest following the instructable form JON-A-Tron on digital fabrication by hand. If you are making the cuts by hand I suggest cutting out most of the detail in the first layer of the top of the case. All of the parts for this project fit easily on a 36 by 24 inch sheet of plywood.

Step 4: Glue

Once the pieces are cut, simply glue all the parts for each layer together. Take extra care to make sure your alignment is good. If you have any alignment concerns go back to 123D and add use the dowel function to add some alignment pins. This is also a good time to glue in the magnets for closure. Apply a small amount of epoxy and to the magnets and insert one in each of the hoes on the bottom and top of the case. Make sure your magnet are aligned properly to attract each other rather than repel.

Step 5: Router Table

Use a 1/4 inch or radius router bit on a router table to round over the corners of the case.

Step 6: Sand and Finish

Any type of wood finish will work for this case. I recommend applying at least two coats of an oil-based finish such as danish oil or teak oil. For the best finish, a small amount of sanding is a good idea before applying oil.

Step 7: Enjoy

Now you can keep your equipment safe in style on your next tour. Enjoy.

Question 1 year ago on Step 4

How thick are the magnets? 1/4” diameter and ???” thick

I think it was 1/4 by 1/4. It should be as thick as the plywood sections.

Is something like this possible with only a CNC mill? After looking around for a laser cutter, it looks like a CNC mill is the only machine I have access to. Perhaps collapsing into just 2 layers and then going from there? Any suggestions would be helpful. Any files people have used to actually do this, even better.

Would you by any chance share or sell your .dxf file so I could build one?

I love your design by the way, I think I could find some oak or cherry wood 1/8 thick.

Finally ordered an op-1 after saving and selling, I'm really excited but I know I'll need a case for sure.

Thanks,

Ryan

I figured out how to convert this to .dxf

I'm going to try this with uv reactive cast acrylic.

I've got some on order, can't wait. I'm going to make one out of wood first and try a few different mods, I thought about an internal antenna or something along those lines.

Thanks for the great build!

Would you share the .dxf file with me?

How did the acrylic case turn out?

Hey, so sorry for the late reply. I was unable to find my original DXF files, but I am super glad you did it on your own. Can you send your version to me, so that I can post it for future users? Also, please please please send photos of your version. I'd love to see what you've made.

Any chance you have the original fusion 360 file? Would love to use a CNC router to mill one out of solid wood. I can stack up the templates and re-extrude if necessary in fusion 360, but it would be easier to just start with your CAD model

Will this 3DF file work? If not I can share a public link. Also, sorry for the sloppy modeling, this was one of my first Fusion360 projects. See step 3 for file.

Any idea where I could get 1/8 inch plywood in New York? Home Depot doesn't carry t :(

I've seen it at Home Depot before. Not sure about suppliers in New York though.

If James bond was in an indie rock or electronic band this would be his control panel for sure.

I really like this case! I appreciate that some people want to make things that look as aesthetically pleasing and professional as the designer of the product. Also, I noticed that there's a phone number on the case. Was it intended for it to be made public?

I'm glad you like it. I forgot to photoshop out the phone number. Feel free to call him for booking a show...
