I don't know for you but I have a beard. This is not a ZZ Top model, but a very elegant mouth-around one... I hope :) I'm not alone, for sure, that's why I think my design can be useful to someone.
There is a lot of comb for the beard here. Most are very good, but mine is different. What is different ?
The small size, designed to fit in the holder of the bank card. But this is not a form of bank card. It is a form of almost traditional comb that can be kept in a bank card holder. Or in a jean's pocket.
The combs I tested are all with square-ended teeth. For me, it's irritating. That's why I made rounded teeth. It's a lot softer.
I noticed that the usual combs have the text in hollow. I made mine in protrusion. It's not only for easthetics but it's to help to catch the comb in the card holder.
As you can see, this Beard Comb Card is a evolved version of the traditional comb. I suggest that you vote for me at the Lépine Paris contest (if I participate one day) :)
For printing (in PLA), I used a 0.1mm resolution (for sweet rounded teeth), a 60% infill and a slow speed of 40mm / s. On my printer, it takes less than an hour.
I hope you'll enjoy it.
