A Comb holder based on my shaver holder design: https://makerworld.com/en/models/47969?from=search#profileId-49823
Its designed for my broad teethed comb, which I bought in a Danish store called normal. I'm sure its a pretty standard broad teethed comb.
I can be printed in upright position with small support or upside down without support, when printed upside down I found the brim to be useful as it has very little surface to stick to the print bed.
