Swedish M29 Tram

Intended for 3d print.

Update 20240210: M29 without any decals or advertisement spaces added to model pack.

Swedish M29 Tram, manufactured by Hägglunds in Örnsköldsvik. A total of 60 M29s were built between the years 1969 and 1972, for the city of Göteborg's public transport. The M29 design is very similar to the earlier M28 and M25 trams, to the point people often confuse the M28 for the M29 and vice versa. The M29 is still in service today, while the M28 was retired in 2021. Last I heard (I am writing this in February 2024) the M29 was due for retirement in 2026, but most local residents will probably not believe it until they see it - the M29 was originally planned to be replaced way back in 2003, but despite numerous subsequent purchases of other tram models, 53 M29s are still in service. The current (2024) Göteborg tram fleet is made up of five different models - the Hägglunds M29, the ASEA/MGB M31, the Ansaldobreda M32, and the Bombardier M33 and M34. For reasons that surely make sense to our municipal politicians.

This model pack contains two variants of the M29 - the "old" version with exposed bogies, and the "modern" version with bogie covers. The old version also has a different door opening button.
There are bound to be minor inaccuracies in these model designs . For example, I know neither the pantograph nor the bogies are entirely accurate. Since the M29 has undergone several updates during its lifespan, there may also be anachronisms here and there. For example, I'm not sure if the M29 originally had three headlights, or just the central one. So three headlights on the "old" version may be incorrect. But overall, I think I've replicated the real-life trams fairly well. Not to toot my own horn, but far as I can tell this is currently the best 3d-printable model of the M29 out there.

The default scale of the models when loaded into your slicer is roughly between 25 and 28mm scale. Obviously, you can also easily rescale them in your slicer. They print as one-piece models, i.e you print the entire tram as a single model. This means there is no post-print assembly, but it also means the models take up quite a bit of space on your print bed. If your printer is too small to print the model, I suggest simply cutting it in half (a command available in most slicer programs), printing one halve at a time, and then gluing the printed halves together. If you want to print the trams at a very large scale, you can even cut the model into multiple pieces.
Note that, at the default 25mm scale, certain minor details will not show up properly. You can solve this by either printing at a larger scale, or engaging a commercial print service like Shapeways or Craftcloud to print the .stls at commercial-grade high resolution quality for you.
I've also included a piece of railroad track in the model pack. I took the piece from another release (a railroad tileset), so the railroad track is not an accurate depiction of a tramway track. I've also only included a straight piece, so you can't use it to build a grid for your M29s (although you can if you purchase the tileset itself. Link below). The included straight piece is mostly for decorative purposes, like if you want a tramway "stand" to place your tram models on.
