I'm a strong believer of "just because you can doesn't mean you should" and with 3D Printing people seem too Hell bent in either doing things with as few 3D Printed Parts as possible thus resulting shapes that - if split apart sensibly - would drastically have reduced the print time or even worse use 3D Printed Parts for things that would have have benefited from being manufactured differently. Both of which I've caught myself being guilty of 😅

Concerning that Bridge that took months to print... With a repeating design like that I'd probably have gone the route of 3D Printing myself a bunch of JIGs which then get populated with the parts made from cut to size raw stock material ( like sheets of plastic, profiles, etc... ) where they then get glued together. Sure... You won't have the leisure of sitting back while the Machine does like 90% of the work but I'd wager it being like 900% faster 😁 Though who knows... Maybe waiting for months on a Model to finish is something you enjoy 🤔

After doing my E-100 and the Experience I've gained from it I'm now occasionally working on my VT 1-2 with the emphasis on using ( new parts ) or reusing ( parts I replaced with aftermarket ones ) as many stock parts as possible for the build to ease its production.
Like a LOT of parts from the Tamiya #56020 Leopard 2A6 Drivetrain ( Tracks, Wheels, Suspension, Photo Etch, etc... ) including the entire Differential Gearbox Assembly IF I can fit it into the Model without having to adjust its width too much.
