Thanks! Found some good models on ... somewhere. Printablep? Thingaplace? Printed in Jesse Beige 500 that's actually a pretty good match for a slightly-yellowed 1200.
My Atari 800XL, C64, and ZX Spectrum 128k are also ready for Revision but they know that they are underappreciated in the scene. Well, maybe not the C64 - that "8 shades of brown" fucker is smug as shit
