DIY Drill Press

Since I've been fabricating a lot of printed circuit boards for some new electronics/robotics projects, I needed a drill press for finishing PCBs and for smaller, more delicate drilling operations.

Introducing the Flex-Press Print!  After looking at some drill press designs, including my crappy Press and a couple from Stritch's metals shop, I decided I could design my own press to be 3D printed.

**Update: Per suggestion by Google User Mike M, I am including a link to the drill press stand that inspired this design  - in case you are interested in buying one, rather than building your own - but also to give credit to the original design.  Check it out, here.

I had an extra flex shaft tool, so I designed it around that.  A similar one could be purchased here.

The design also features LM10UU 10mm linear bearings to ride up and down a 10mm diameter shaft.

My studio mate, DeLandTree, inspired me to include a time lapse of my initial drawing for this design.  Check out his latest time lapse cad session here.

I decided to design this to print on my Mendel Max printer because: a.) it would be fast, b.) it would be a design worth sharing, c.) it could easily be designed to be printed with zero support material.


I published this design on Thingiverse, here.  Above is all of the parts fit onto one 190x170mm build plate, tho I actually printed each of the parts individually.

The first print: the z-axis clamp.  This includes a small 1/8"x10 ruler for depth specific drilling, as well as a nut-trap for a bolt to act as a clamp on the 10mm shaft.

For the base of the press, I decided to try a little experiment.  Though the base of the press needed to be sturdy and heavy, I designed it to be hollow.

And laser cut a "lid" to screw on top of it.

Then, I used hot glue seal the seams.

Next, I began to fill with concrete.

I sprinkled in some extra bolts to add some weight.

The base, filled with concrete.  I attempted to add some flange nuts so I could anchor this to a table in the future; all but one sank below the concrete (sigh.)

The completed base.

Tho I didn't include images here, the other two parts came out near perfect on the first try.  Also - I tweaked all of the designs to compensate for little bugs before uploading to Thingiverse.

For levers, I cut, bent, and filed some .125x.5x" aluminum strapping.

Drilled and tapped.

Plasti-dipped the handle lever to maximize drilling comfort.

The completed press!


  1. This press drill is strongly "inspired" by Foredom PD-30 Press Drill Stand. The stand that is actually designed to use with that H.30 flex tool handpiece Bryan Cera is using. For about 100$, heavy and sturdy iron cast, I don't think it is worth the trouble to 3D print it and end up with a light plastic stand. Just my 2 cents.

    1. It's cool Bryan that you modeled a 3D version, but at least give the credit to Foredom for the original design.

    2. Mike,

      I modeled this based on an unidentified (unlabeled) and broken press I found in metals storage at my university. Thank you for identifying the model for me! I have updated this post per your suggestion.

      Three things I must note:

      1.) While the model I drew is inspired (no quotes necessary) by the Foredom press, I made many changes to the design in order for it to work with 3D-printed parts and off-the-shelf hardware. Have a closer look at the models and you'll see that they are modified, more than 70%, from the source.

      2.) The point of this project (and many others I make) is to encourage my readers to try their hand at creating their own tools, rather than simply purchasing them. Making my own tools has been a great way to learn about materials, fabrication and design - whilst growing my personal workshop.

      3.) This press cost roughly $14 to build - quite lower than the $140-150 (not sure where you got $100 from) price point of the foredom model.


    3. Oh, and also, it may be plastic but it is not light - if you actually read the post you would may have noticed that I filled it with concrete! :)

  2. 2 days ago, I told about about Jim's WoodProfit course.


    I've spoken on the phone with Jim Morgan and I'm just
    blown away by his simple and effective strategy to
    make money using his basic woodworking skills.

    He started his woodworking business with NO capital,
    a few shop tools, and a lot of nerve, in a small
    10x20 foot space and grew it into a 1,400 space in
    the first few months while still remaining as a
    one-person business!

    See his story at:

    Now if you want earn some pocket money during this
    recession and run an easy to start and fun business,
    then you'll LOVE this guide.

    It contains all the information you need to start making
    money from the very first job...
