Toss out that boring, old razor handle and make yourself one of these! I’ll show you how to make an attachment that you can use to connect your razor to practically anything else you can 3D print. This attachment is compatible with Gillette Venus razors (I believe Gillette Mach 3 razors are the same as Gillette Venus so it should work on those as well).

Step 1: Measure

I started off by measuring of the base of the razor head and the upper part of the razor handle.

I pulled off the razor head and using a caliper, measured the oval shaped base of the razor head (21mm x 6.4mm).

Then, I took a look at the handle. I took it apart and measured everything! The little white piece that sticks up, the spring that’s attached to the little white piece, the hole that the spring was sitting in, the trapezoid piece that sticks out and actually connects the razor to the handle. But, in the end I discovered that all you really need for basic function is that trapezoid piece that extends up out of the handle (top length: 12mm, bottom length: 14mm, height: 2.5mm).

I also measured from the side to see how far I would have to extrude the shapes.

Step 2: ​2D Design: Inkscape

  1. With the measurements, I drew the shapes in Inkscape. I needed to make 2 shapes: a trapezoid like the one on the handle and an oval like the one at the base of the razor head.

Before starting, go to File>Document Properties and change the Default Units to mm.

Side note: I’m not sure how much the stroke impacts the final size of the object, you don’t want your stroke to be too large, when I made mine I didn’t pay attention to the size of the stroke but it’s probably best to keep it between .01 and .01. To change the stroke, go to Object>Fill and Stroke and set the Stroke Width to 0.1mm

Oval:

  1. Select the Rectangle and Squares tool from the left hand column (blue square icon).
  2. Left click and drag to create rectangle.
  3. Under ‘Change’ enter the values: W: 21mm, H: 6.4mm, Ry: 3mm (to round the corners)
  4. Save it to your computer as rectangle.svg

Trapezoid:

  1. Select the Bezier Curves Tool
  2. To create a straight line: Left click, hold down control and move the mouse to the right, left click create endpoint, release control, right click to finish.
  3. Go to the select and transform tool (black arrow) and change W: 12mm
  4. Use the same method to create the 14mm line
  5. Select everything (Ctrl+A) and change the stroke width to 0.1mm if needed

Arrange objects:

  1. Select all objects.
  2. Go to Object> Arrange
  3. Change Rows: 2, Columns: 1. Spacing: y=0mm, x=2.5mm.
  4. Hit ‘Arrange’ to align the objects.

Create the sides:

  1. Double click the top line (if it isn’t already selected) and a little diamond should appear.
  2. Left click the diamond and it should get bigger.
  3. Hold Shift, click on the bottom line, a little diamond will appear on that line, while still holding shift, left click the second diamond.
  4. At the top, select the icon that says ‘join selected and nodes with new segment’. This will create one side of the trapezoid. Do the same thing for the other side (but since the object is already selected you don’t have to double click the top line this time).
  5. Save to your computer as trapezoid.svg

Step 3: 3D Design: Tinkercad

It’s time to make 2D objects into 3D objects!

  1. Go to tinkercad.com and create a new design.
  2. Import rectangle.svg and trapezoid.svg into your design (Import> Choose File> Import).
  3. They might not be to scale so you’ll probably have to resize them.
  4. Oval: 21mm x 6.4mm, Trapezoid: 14mm x 2.5mm
  5. You can either use the box and drag the corners to resize, or lay down the ruler and click the values to change them. They don’t have to be exact, just try to get as close as you can.
  6. Extrude each of them so that they’re 7mm tall
  7. Drag the trapezoid 7mm up into the air.
  8. Select both and align so that they are centered.
  9. Select both and group.

Before moving on, do a test print of the attachment to make sure it actually fits the razor!

After you know that you have a good fit, import an object that you want to act as the handle for your razor. I chose a cute little dragon, but you can choose ANYTHING! The dragon I chose came from thingiverse, cute dragon by bs3 www.thingiverse.com/thing:1469139https://creativecommons.org/licenses/by/3.0/, I just added the attachment piece to it to turn it into a razor handle. In this particular piece, I put the attachment in the mouth of the dragon.

  • Scale it down if needed and move/rotate the razor attachment so that it overlaps with the other object.
  • One you’ve placed it, save for printing.

Step 4: Printing

Print with supports if there are overhangs. I used PLA.

Mine came out kind of weird in some spots…I still haven’t gotten the settings/ calibration on the printer (Rigidbot) down right. Break off the supports and sand where needed. I ended up painting it with a few coats of nail polish but I'm not sure how well that will hold.

When you’re done, attach the blade and shave everything!

Thanks!
