This model needs to be used with dowels. The holes of the mount are having 23 & 24mm and should fit 22mm of (wooden) dowels (like in my case). If there are any troubles i've uploaded the cad model for adjustments.
If there are a lot of wished for a certain measurement i can adapt it aswell :)
I recommend it printing with some more infill and maybe thougher materials. Maybe you have to check on your own. In any case just use more of the mounts inbetween of a dowel.
If it's very close and the dowels are barely not fitting - just use a little sanding paper and sand down the holes.
