Elegoo Mars Fix for missing layers

thingiverse

These files are a direct result of my experimentation with ideas presented in Alex Whittemore's and Jan Mrázek's blog posts, which highlight some design flaws in the Eleegoo Mars DLP printer. The Mars is an exceptionally fun machine for its price, but it has too much play on the threaded rod inside the stepper motor housing. This excessive movement leads to missing layers of up to 1.4-1.5mm height, most noticeably when printing layers with larger horizontal cross-sections due to the drag on the Z axis. To resolve this issue, I added an extra spacer in the motor housing and replaced the rubber damper with a solid plastic mounting block.
