I was heavily inspired by this bowl as it's performance is impressing, especially wiper is of much use. I did print original version, but it suits for `~20mm` brush knot and its ok for most of the brushes.
Perhaps your **brush knot** is about **`30mm`** - here is the version of this excellent bowl with suitable wiper.
> The actual wiper width on top is **`28.5mm`**
