Direct Drain for Camper Van | 1½" Sink to 20mm

Direct Camper Van Drain

A compact direct drain designed for camper vans where there isn't enough space for a conventional trap.

When I modified the furniture in my camper van and moved the sink, the new installation was lower than before. There wasn't enough room for a conventional P-trap, so I designed this compact solution.

It allows the sink to drain directly into a grey-water container, without having to remove the container every time the sink is used.

🔧 Compatibility & dimensions

- Sink/drain connection: 1½" threaded drain - Top diameter: 32 mm - Outlet diameter: 20 mm - Outlet: 20 mm tube/hose can be fitted if you want to route the water somewhere else. - A metal hose clamp can be used to secure the hose. In my installation, the 20 mm outlet goes directly inside the grey-water container.

⚠️ Please check these dimensions against your installation before printing.

🖨️ Printing

I printed mine in PETG , which I recommend because the part is exposed to moisture and needs to withstand long-term use.

The included print profile is the one I used for my own part.

💬 Feedback & modifications

Have you printed it? I'd love to know how it works for you!

If you need a different size or a small modification, leave a comment. If the change is reasonably simple, I'll do my best to adapt the design.

If this design helped you solve a problem without buying another part, a Like or Boost is always appreciated. 😉

Repair it. Reuse it. Don't replace it unnecessarily. ♻️

Fighting planned obsolescence, one useful print at a time.
