Another take on the Igt/Eus motion blocks and carriage.

Another take on the Igt/Eus motion blocks and carriage. I took the exact opposite approach to @ThantiK and decided to fillet almost none of the things.

fillets in a machined part don’t usually make sense. But besides looking good and saving a hair of material, fillets in a printed part can also slightly to moderately increase strength (reduced stress concentrations and increased surface area for layer adhesion.) When the cost is only a few clicks in your modeling program, why not fillet?

Originally that was the plan - machine the XY blocks and carriage from aluminum like the rest of the machine. This proved to be unfeasible at my level of expertise. So I beefed the design up and went with plastic. I could add some fillets, but they’d be in the belt path.
