EtchedPixels@fbbfb1c would be too expensive, and would also need a whole additional level of detailing work to be useful. Not something I have time to do
EtchedPixels@trio Its sized to scale and will fit a thinned down Kato four wheel chassis - you've got about 16mm wide x 69mm long. The chassis needs to stay no more than 5mm above floor level to avoid being visible through the windows.
EtchedPixels@oliverturner88 ping me after Christmas and I'll do a quick rescale and see what it costs. I'd not bothered as there are a bunch of other 48DS kits in OO.
EtchedPixels@Md91 it gets really pricy by the time it gets to 4mm size, and in 4mm some bits aren't thick enough to print in WSF. 4mm has a lot of existing 48DS kits.
