Almost every Maker has used a multimeter, if it was testing batteries or continuity. I know that whenever I do this, I can never seem to get a good test because I’m trying to test with one hand and read with the other. In other words it gets cumbersome.
I have created a project that solves all of that!
Step 1: Before You Start
You will need a multimeter. I would suggest the one in this picture. The Meter is inexpensive and easily replaced, this makes it great for a tinkering project.
You will also need some glue. I like “Epoxy” but super glue will work just fine.
I would suggest some kind of wire brush for a rotary tool. The brush can be stainless steel, brass, or even nylon. This is to clean up the parts after printing.
You will need access to a 3D printer. If you can’t get your hands on one, you can sent the parts file to a 3d printing company and they will print it for you.
Step 2: Lets Get Printing
I was experimenting and printed all my parts in ABS. The material choice is up to you (just don’t print in flexible material HAHA). All my parts were printed at 200 microns. I think that is great quality considering this isn’t a very complex print.
There are 3 main parts.
1. The first part will connect to the back of the multimeter with screws, that’s later in the project.
2. Part 2 is the connecting base for everything. This will need to be printed with light supports.
3. Part 3 is the legs that connect to the base. You will need to print 4 of them, no supports needed for this one.
I have uploaded the design file so PLEASE feel free to make it your own. Add a pattern to the legs or find a way to make it better, and if you do let me know.
Step 3: After Printing
After you finish printing all the parts, I would suggest some clean up.
Cut all the supports out of part #2, be gentle, you don’t want to have to print another one.
Next, I used a wire brush on my rotary tool to smooth out the plastic. After that I dry-fitted all the parts together to make sure they fit.
Next is glue!
I mixed up some Epoxy to glue the legs to the connecting base. Let the glue set up and move on to the next step.
Step 4: Attach the Multimeter
Remove the screws from the back of the multimeter. Then take some longer screws and thread them back into the hole with part #1 behind the screw head. Make sure part #1 is secured to the multimeter as shown.
Step 5: Bring It All Together
After the glue is dry and the multimeter is secure to the back, use a ¼ inch nut and bolt to connect the multimeter base to the stand. There is a hex hole on the side that the nut will fit in to. Next tighten the screw and connect your multimeter’s leads.
