How it worksFiles, not freight

Buy the files. Print the boat.

TMRC designs are built for desktop printers, not industrial machines. Large hulls arrive pre-split so they fit a standard bed.

  • Instant download. Files land in your inbox at checkout - nothing ships.
  • Split for 250x250 beds. Big hulls come sectioned as well as whole.
  • Runs on PLA, PETG or ABS-CF. Print settings included with every pack.
  • Hardware to match. Brackets, stands, drive systems and decals designed to the same tolerances.
  • Digital sales are final. No refunds once a file has been delivered.
