The RAF used this model of the Houchin GPU until the 1990s on many aircraft types of all sizes. They had a Dual lead and 3 & 6 pin square connector for AC & DC power supply. Handy for those airfield diaramas.

The model comes in a one piece and an exploded version. No cable is included, but the connectors are, so use thin wire or nylon thread if required. The exploded model has the option of open doors & cable troughs. 2 versions of each are supplied, one with radiator doors and one with radiator louvres. NEW: added a zip with individual part files for ease of printing.

The size of the of the one piece object is X: 1.36182m, Y:3.5051, Z:1.61943m The Exploded object is X: 4.303m, Y: 2.25413m Z: 1.42876m

Scale Settings:Useful settings: For 1/72th, Scale = 1388.888%. For 1/48th, Scale = 2083.333% . For 1/32th, Scale = 3125.000%.For 1/24th, Scale = 4166.666%

How to calculate this percentage for the slicer without knowing the model dimensions. First we know that the model unit is 1m, and has been interpreted by the slicer as 1mm. 1m = 1000mm, so to get the right scale, divide 1000 by your scale. EG 1000 divided by 48 = 20.83333. Now multiply the result by 100 because we need a percentage. The final result is 2083.333 as shown above. All other scales use the same formula.

See the last two screenshots for examples of a 3d printed model and the orientation used, printed at 1/48th scale. Print using the smallest layer size for best results. Make sure that thin objects and undersides have plenty of supports.
