And better oil retention.Ĭould the T-Jet chassis design be improved? Oh God yes. Also less dimensional change at temperature. Not least of which is much higher heat tolerance and better heat dissipation. I'd strongly favor replacing the molded-in bearings for the armature with Oilite bushings. My first candidate for material would be PETG, although Nylon would be more heat-tolerant. Otherwise there doesn't appear to be much challenge to printing a pancake-motored chassis. The whole electrical underpinnings need to be rethought. Minor mods, like locating the gear plate with projections off the main chassis, rather than projections off the gear plate itself.Īlso ditching the leaf springs for the commutator brushes, replacing same with coil springs. At first glance it looks like a few minor mods would make it eminently printable.
The venerable pancake chassis design has been stuck in limbo for dang near 60 years. So, has anyone been experimenting with printing HO chassis? It's high time this forum lost its virginity.
