Power Button for electric shaver

When the power button fell off my electric shaver, I was a little sceptical as to whether it could be replaced with a part printed on an FDM printer. This is a rather small and fancy part. On the other hand, it's a quick print, so why not give it a try. The first attempt was a complete success, the button sits in place and the small locking elements have withstood several months of daily use.

Print settings:

• Layer height: 0.1 mm
• Perimeters: 3
• Solid layers - top/bottom: 9 / 7
• Infill: 15 %
• Supports: No
• Material: PETG

The button is splitted into two parts to optimize 3d printing. Height of assembled button should be 4 mm. Overhangs could slightly increase the height - in such case the hole surface should be smooth out.

I only carried out the installation once a few months ago, so the following procedure is only indicative.

Assembly:

• place the shaver in the position as shown in the photo;
• insert the spring that was placed under the original button;
• turn the button so that the plane of symmetry of the button is parallel to the left-right direction;
• if I remember correctly, the convexity of the small part inserted in the bottom hole must be on the right side (assembled should press the switch on the shaver);
• first insert the locking elements on the left side of the button into the corresponding holes on the shaver;
• gently press the right side of the button until it clicks into place.
