Tritonia waveguide was one of the first ATH designs using the smooth-curvature transition of the OS-SE[1] profile. It was originally designed and optimized for infinite baffle conditions, and as such, depends on an enclosure design. At the time it was believed that to eliminate the on-axis problems associated with most round waveguides (of that time), one has to make the mouth less symmetric - elliptical or rectangular, for example. This was before the advent of the latest free-standing devices, but the original design is still pretty good and can be used in a typical loudspeaker enclosure, if that's what's preferred, for whatever reason. We believe that this waveguide can still make many audiophiles happy with its performance.
With the increasing spread of readily available 3D printers among audio DIYers, it thus makes sense to take the original design (intended for CNC milling) and offer a convenient STL kit -
The first kit available, called Tritonia-S (for "small"), is a reduced-scale version of the original, modified for a slightly wider coverage, intended for a 1" compression driver and to be used from roughly 1.5 kHz. The front dimensions are only 206 x 178 mm, so the waveguide can be printed in one piece on most 3D printers. The nominal coverage is 100° x 90°, although the enclosure (or lack of) can still alter this to a degree. The throat opening angle is 20° but it's not really critical in this kind of waveguide with a rapid throat expansion. There are no replaceable throat adapters for this design.
It's not strictly necessary to build it into an enclosure, it can be left standing (for example) on a midbass cabinet, although the performance will typically suffer to a degree (you can see such results here). A properly rounded enclosure should provide the best acoustic conditions. Anyway, in the kit there are several versions of the waveguide for different mounting options. Complete Ath code is provided so it's possible to simulate the waveguide in a custom enclosure even before purchasing the kit.

The second kit is still a 1" throat, reduced-scale version of the original, but larger than the "S" version. The front dimensions are 294 x 254 mm (11.6" x 10"). It's also designed to be printable basically in one piece on larger 3D printers. The acoustic qualities are maintained and extended a bit towards lower frequencies. It's supposed to be used down to 1 - 1.2 kHz, depending on a driver used.
