MGB Roadster MK1 Toggle Switch Caps

thingiverse

This is a set of toggle switch caps for the MGB Roadster. I made them for a 1965 MK1 ('62-'68), though they may be usable on other models. The plastic caps on the toggle switches had degraded to the point where they were not salvageable, so I designed some new ones. Though the switches are available aftermarket, the caps alone are not (at least, I couldn't find them) The original caps do not have any markings, but I added some recessed lettering to make the switches more identifiable for their specific purposes - wipers, lights, heater fan. I also included a non-lettered version if desired. There are also two variants: one with a reinforcement ring (printed in an alternate orientation) and one without. I was concerned that they might split along a layer when forced onto the switch shaft, but I don't know if that fear is really founded. Feel free to experiment! Note that these are not exactly the same shape as the originals from the factory. I beefed them up a little to make them stronger. I printed mine in black ABS and wicked some superglue on the layers and the rings to help strengthen them. To get them shiny, I sanded them with 220 grit paper followed by 400, 1000, and 2000 (it actually goes really quickly) Then I polished them with car polish on a rag. I think they came out pretty good! The letters were then filled in with white model paint. They fit pretty well on the switches, but I did have to sand off some rust on the posts to get them on all the way. The model is available on Tinkercad if you want to mess around with them. Happy driving!
