This is a set of 1mm - 14mm extensions for the Philips OneBlade shaver.
Originally I designed the shaver extension for a length from 8mm. So far I have only printed 8 10 and 12 mm.
Nevertheless I designed the smaller extensions , I hope that they work just as well.
If the shaver extension doesn't fit on your Philips OneBlade, it's the calibration of your printer.
Easiest solution: Scale the part in the slicer to fit the pressure on the razor without soldering.
Don't just print a single shaver extension, otherwise the print won't be good, or use a cooling tower. (http://matthewtmead.com/blog/fixing-print-details-with-a-cooling-tower/)
To make the surface of the shaver extension more comfortable, hold it over a lighter for a moment, this will melt away the sharp edges.
