3D printing objects I’ve designed. Usually released on Thingiverse.

Box Fan Filter Variable Speed Fan Build

Building your own box fan filter is a great way to reduce the amount of dust in your workspace. And you can build it for just about the cost of the fan and a suitable filter.

I’m taking that one step further and adding in variable speed motor control inline with the box fan filter itself. For the cost of an additional triac to chop the voltage to the motor I’ll be able to trim the fan speed up or down depending on the amount of noise and airflow I’d like.

Drill Press Squaring (with 3D Printed Tool)

Last week I was attempting use the Craftsman bench press to center drill Titanium bolts with HSS drill bits.

As you can see I was successful at drilling and an utter failure at drilling straight. In hindsight assuming that the table was square enough because it had been bolted and pinned in place was a mistake.

Titanium bolt with a hole drilled through the threaded side.

Improved Filament Spool Holder (with optional motor)

If you need a spool holder that does the job and has an optional mounting area for a DC brushless motor, here it is. I still need some refinement of the motorization option. But it’s otherwise functional.

Sure, there were quite a few other spool holders. None of the ones I browsed on Thingiverse had a license I liked. So I created my own.

Feel free to use or modify it! If anyone has suggestions post them up and I’ll accomodate them if they’re something I need.

And I also shot a video of putting it together. Along with the features that I’ve added in so far.
