A printable model of the two main components of a worm drive.
With a little stand indicating the gear ratio.
For the best results, the worm shaft is printed in halves and then glued together.
Printed in PLA on a Reprappro Mendel (single colour) with a 0.5 mm nozzle and 0.3 mm layer height.
No support material needed, since the worm shaft is split in half and glued together with glue (used for building model airplanes, etc.)
