Miata Transmission Output Seal Installation Tool
This is a simple tool to evenly install an output seal on a 5-speed Miata transmission without damaging the lip.
Print with 3-4 walls and 50% gyroid infill. Supports optional. Print at 75% height if you're in a hurry. Full height just easier to grip.
With these settings, a PLA version will happily survive significant and repeated blows by a 16oz claw hammer, with much more force than one uses to drive the seal.
