This is a remix based off of a design by cporto, and includes:

• additional supports which strengthen the print
• more, smaller gaps to block small objects from falling through
• a wide cover and long center post to prevent thin objects like hairpins from falling through

It's designed for a 3 cm wide drain, and may be a tight fit.

I printed this with high resolution to make the print smoother, but it will work fine with thicker layer height.

If you use PLA, I recommend printing at higher temperatures(at least ~210°C) for extra strength.
