Introduction: 3D Printed Ratchet Screwdriver

About: Hi, I'm Johan Link

I created this 3D printed screwdriver because I wanted to make an object, beautiful, simple but also functional. I also wanted that this object is printed in one piece. This is an advantage of 3D printing. The object is more solid if it is made in one piece, and you don't need to assemble it.

This screwdriver is not a simple screwdriver, it's a Ratchet Screwdriver. You can screw and unscrew the screws quickly and easily with it.

How screw and unscrew with this screwdriver? If you want to screw, put the bit on the top of the screwdriver. If you want to unscrew, put the bit on the bottom of the screwdriver. It's simple and effective.

Step 1: The Design

I spent a lot of time designing this screwdriver. It has a sober and elegant design. The grooves on this screwdriver are like the grooves of the standard screwdrivers. This design is simple but effective.

Step 2: How I Created This Object?

To model this object I used Fusion 360. I use this software for a short time, it was a challenge for me to model this screwdriver with its mechanism. Fortunately Fusion 360 is really simple to use, and this software is very intuitive. This is the first time I make such a complex object in Fusion 360, so I may have made some mistakes in the model.

You can also download the STL file if you want to print this screwdriver.

Step 3: How It Works?

As I said earlier, this screwdriver is a ratchet screwdriver, so there is a mechanism inside it. As you can see in the pictures, the screwdriver is made up of two parts. Both parts are printed at the same time. The part inside the screwdriver contains a cogwheel, around it there are three wings that bend when turning the screwdriver. This screwdriver makes the same sound as the real ratchet screwdriver, it makes CLICK, CLICK, CLICK.... (You can hear this sound in the video which is in the step 4)

Step 4: How to Use It?

It is very simple to use. Just put the bit on the top or on the bottom of the screwdriver. One side of the screwdriver allows to screw and the other allows to unscrew. You can watch the video to better understand.

Step 5: Print!

If you like this design you can download it and print it. :)

I print this screwdriver with the K8200 printer, and I use Cura to generate the G-code.

My Print settings:

  • Bottom/Top thickness 0.5mm
  • Fill Density 20%
  • Platform adhesion type: Raft (it's not necessary)
  • Support type: Don't use support!
  • Use PLA or ABS.
