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 past (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 face, 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 slowing 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!

Programming with OpenSCAD

I recently picked up Programming with OpenSCAD from No Starch Press. I’ve been using OpenSCAD for over 10 years, and I’ve not yet mastered it, but I’m definitely proficient at it. I’ve learned a lot of tricks over the years and I’ve created some complex 3D objects, but there’s always more to learn.

So did this book help? Yes. I read it while I was “offline” (meaning, on vacation away from home for a week) and it was good to just read a book and have a reference without being distracted by a computer. If you’re a complete newbie to using OpenSCAD, this would be a great book for you. I could still do most of what I do without ever having read it, but I feel like I picked up enough tips and tricks to make it worthwhile.

Other things to check out are the OpenSCAD Cheat Sheet, and the GitHub repo for the book which has all the code you’ll find in the book in case you want to grab any of it.

Wyze Cam Magnetic Shelf

I needed to mount my Wyze Cam to a metallic door but still wanted it upright (and not sideways) so I made a small shelf, added magnets, and stuck the metal plate that came with the camera onto it.

I used 12mm x 3mm magnets, so the pockets are for that specific size. I didn’t glue them in as they fit really well, but did add some gaff tape so they don’t fall out.

If you’re familiar with OpenSCAD you can modify the .scad file to allow for different size magnets. I seem to have a large pile of 12mm x 3mm so I just used those.

The metal plate that comes with Wyze Cam has a mounting hole in the center but also has adhesive, so I just stuck it right onto the shelf. It should stay put just fine. (I probably could have used a few washers as well, but I have a few of these plates now.)
