These guides where designed for a 60mm wide whetstone block. I have included the Fusion 360 file is you want to make it thinner or wider.

I recommend printing them with the label side down and to use a smooth plate if you can. There is no need for supports or a brim

Info for when to use certain guides:

13° - Serrated knives are usually 13° or lower

15° - Thinning knives or secondary bevels

17° - Japanese Chef's knives

19° - Thin pocket and paring knives

21° - Most Kitchen and every day carry knives

23° - Thick pocket and hunting knives

25° - Any knife that is too thick to get an edge at 23°
