I've gathered all the TRX4M Modular track models from @Ed_28374 on Printables and combined them into a single project with proper settings (supports enabled on required pieces)

Full credit goes to @Ed_28374 for these models. These modules are original in their entirety, I did not modify them at all, I just organized them and labeled each plate to make finding and printing everything easier. Sharing license & attributes match original creator.
