Pin Bender (or Unbender)

I often use these rotary encoders that come with right angle pin headers, but I don’t want right angle pin headers, I want straight pin headers. So I designed a small tool to fix that.

The Pin Bender (or Unbender) is useful for straightening (or “unbending”) header pins. Got some 90 degree pins you wish were 0 degree pins? We gotcha covered.

Slide the Pin Bender onto the pins, and then unbend! (Or straighten. I don’t know… you choose the terminology you like best.)

Now bend it… like somebody who bends things. (Bender!?) Now you got some straight pins. Or zero degree pins. Whatever.

Pretty cool, right? Did I mention it’s parametric? Well, it is. You want to edit the OpenSCAD file to make one for 8 pins? Go for it. 6 Pins? Okay. 13 pins. I guess so. All yours.

The (In Progress) Tool Holder

It’s been a while since I posted about The (Old) Tool Holder but I did make some progress… Twice! I worked on the holders for wire cutters and wire strippers and made some progress.

I was mostly pleased with the wire stripper holder, though I can see a few improvements to do next time…

I do like that I can reorder the tools if needed. That was one of the main ideas of using the dovetail connections…

This version lasted about a day or two. I got annoyed by the holder for the wire cutters and made a change to the model…

And then I printed another one. Oh, yeah, I did end up changing the filament so we get a nice Prusa golden color this time!

The small modification help keep the wire cutters closed and they sit better in the holder. With the old wooden version I just sort of hacked at the wood so I could jam the cutters in and they would hold in place and hold shut. With modeling something it’s a bit different, but we’re getting there!

The (Old) Tool Holder

Tool Holder

Back in February I got sick of the tools I use most at my soldering desk just lying in a pile and decided to do something about it. I grabbed a block of wood and started drilling holes so I could place tools into it standing straight up. This would make them easy to grab and hopefully easy to put back… in the same place each time. The block of wood has worked well enough, but more than once I’ve wanted to change the order of the tools, and I can’t easily do that since each hole is customized for the tool it holds.

It was also a fun time creating the holes for the wire cutters and wire strippers since the holes are sort of oblong. I actually did pretty good for freestyle drilling on those. At the time I also imagined a modular system for this, and a month later I found a dovetail library for OpenSCAD and started messing around with it. I could not get a good dovetail joint to print though, so I gave up for a while.

Tool Holder

A few more months passed (hey, I got busy) and instead of printing the dovetails on the old Maker Select Plus I tried on the Prusa MINI+ and wow, things fit perfectly! Well, after a few tests prints to determine the exact Teeth_clearance to use. Once I had that, Bob was my uncle!

Tool Holder

Here’s the first successful attempt. The pieces fit together well. Not super-tight, but not too loose. A small strip of tape on the bottom of the blocks would work well to hold them all together as one piece, with the ability to easily take apart and reconfigure. (The first dovetail attempts required a hammer to assemble and could not be disassembled!)

I’m still considering this prototyping, and I may tweak things a bit more before the final version… When I have something final I’ll post it here. My first thought on this version is to make the blocks a little smaller so the tools are spaced together a bit tighter. This should save a bit of desk space as well.

Hygrometer Filament Roll Holder

I recently got a Sunlu Filament Dryer Box and I’ve seen a few people mention that putting a hygrometer inside of it (and another on the outside) can give you a good idea of how much it lowers the humidity. Rather than just sticking it inside the top of the clear cover I decided to make things more complicated and put the hygrometer in the center of the spool so it could spin around and I could practice reading things upside down.

Note that every roll of filament from every manufacturer may have a different spool hole diameter. In fact, even the same damn roll of filament may have different diameter holes on each side! Don’t bother printing this for a snug fit, just make it too small and add some tape either on the body of the print or on the lip to hold it to the spool. The spool is slowly spinning around so it’s not like huge forces will send it flying out into space.

Band Balls

If you liked Band Ties you’ll love Band Balls. Maybe not, but I made them anyway. Just like Band Ties you need to supply your own rubber bands, but you’ve probably got a bag sitting in a drawer somewhere.

Secure those pesky cables! Attach a thing to some other thing! There are 101 uses that I will not list here today!

To attach the rubber band you can cut it, thread both ends through the two holes, and then tie them together… Or you can thread the whole thing through both holes and loop through/around itself.

Print in any color you like. There are no rules! You like blue? Blue might look good.

Too small? Scale it up! Holes not the right size? Fire up OpenSCAD and make some changes. Have Fun!
