3D Printed Resistor Tester Stand

[ToneAlchemists]

Hey pedal builders, I recently found a fantastic 3D-printed resistor and diode testing stand that I wanted to share. It features metal inserts, which are perfect for quickly and accurately testing components with your multimeter. I've been using it for a while now and it's definitely a time-saver!

If you're interested, you can download the STL file here:

Here's a video that demonstrates how it works:

that is so unnecessary, wow

I like it.

When I'm testing resistors I inevitably wind up bending the leads in the process ...
(which doesn't really matter 'cause they'll get bent when I go to populate a PCB with them).


I'd probably wind up bending the leads using this Resister Tester Stand, too.


Unnecessary, but ... I like dodads and gidget-gadgets — my bench is cluttered with such things.


For example, I got one of these that I never use:

The Resistor Tester Stand could sit next to the bender.... SQUIRREL!

Gotta get me one of these!

I like this Transistor-leg bender. Another thing I'd buy and then set next to the resistor-leg-bender.




Anyway, I like the idea of the Resistor Tester Stand, alas I don't do any 3D printing.

For example, I got one of these that I never use:

Yeah,, I have a resister bender that I 3d printed, I use it all the time to bend resistor and diodes. I'm not into guess bending resistors with needle nose pliers. I was going to get one these U and F Type Resistor Axial Lead Bend Cut & Form Machine from Aliexpress to crank out heaps precise bent resistors, so I don't have to bend resistors. lol..

Makers World (Bambu Labs - 3d Printing Models and Community) has alot of good electronic tools and gadgets.

That is so cool! Do you have an stl file for it? Or whichever file printers take lol

You can download the file off the thingiverse website, I used a bambu labs p1s printer which printed out fine, - https://www.thingiverse.com/thing:1673529/files

Thank you!

I'm holding out for a good solder bending jig.

 

[iamjackslackof]

Totally disagree. It's not super useful to measure one resistor, but if you have any number at all, being able to throw each one into the jig and not have to mess around with multimeter leads seems amazing. I won't get one printed, but the second I need to sort a bunch of components, I'm coming right back here to this post.

It’s not about using it, it’s about being able to use it if you wanted to. I’d love to have one I’m not using, also. I also have a drawer full of cool things…around here somewhere.

That Gattlin' Gun-like Resistance Molding Machine looks like fun.

Any time you've got to batch process something, a little widget here, a grapple-grommet meshing with a filber-flange there...ADDS UP to a lot of time saved.


Bending solder, well... I dance a little jig every time I'm about to solder — I haven't jigged for ages, reeling from it.

Gotta get me one of these!

These are very cool.
I searched for a transistor lead bender on various 3D design sites but couldn't find this.
It would be nice if the piece also bent the leads for you, by just pushing the transistor against a set of guides.
Hmm, next time I'm working w/ CAD (I use FreeCAD), I'll see if I can make something like this.

@Feral Feline - so I made a first draft CAD design of a "wire-bending" TO-92 transistor tool, will print it later this week for testing. The basic idea (a.k.a. "hope") is just to press the transistor down into the slots (also pressing down on the leads). We'll see...


Front and back views, the whole thing is just an inch high (25mm).

 

[Feral Feline]

That is something that I WOULD USE!

 

[darwin999]

@GAStan kindly reached out and made an excellent suggestion, to make a 2-piece design with a base unit which holds the TO-92 transistor plus a hand tool (a.k.a. 'lead former') that bends the outer leads into the correct shape. So here's an attempted design for that. What I haven't done yet is test print it, lol... As there's some fine details here, there's ample reason for this to not work out so well. I'm working on printing both the previous 1-piece design shown in #13 above, as well as this new design. We'll see, give me a few days' time - and please cross your fingers.

Here's the base unit that would hold the TO-92 transistor (flat side face down).

Here's the hand tool, in roughly the right orientation that would slide into the base unit to bend leads 1 & 3 so that they now align with 0.1 in (2.54mm) lead spacing.

And here's the underside of the hand tool.
