These are the desiccant containers I am printing now, in PETG. Less pretty, but I think they are more functional.

Most of the stuff is together. (obtained wise) Mounting etc is a big part of the 3d printer. But likely after the engine room.

The smaller pie is planned to manage the solar dump. along with a diesal air to water heater (Bobil Van) Linked in but only temp shut off via the pie.

All the mounting etc comes after the bilge and engin electronics.

Likely early 26 for finisjh given our mobility. (edit: and poverty, that's the bit that takes longest:)

Thanks for remembering

Some corrections.

The boat and the workshop are separate. My brother and I share a 25ft x 6ft10inch narrowboat. We tend to travel over spring and summer swapping over as we move it around the UK.

The tiny area I scanned (not well) was the engine room as it is under tge rear deck so low down small and cannot like many boats be opened from the top.

Hence the need to measure things to layout access.

The workshop is in my 2 bed home. So less crowded.

It is cool that you remember the stuff. When the boat is done I'll def share pics. But my mobility and costs mean its likely to be a year or 2 before all is done.

Desiccant is used a lot in boats. ( in the uk at least where damp is an issue )

But is a different way to 3d printers. It's more about directing condensation.

My thought is to build desiccant holders to mount near the boat windows. (not sure your location if you dont know narrowboat, So ill describe the issue)

My boat was built in the 1970s so is currently single glazed. We plan to do a complete rebuild of the inside and the glazing. But poor again so time.

This design tends to mean condensation builds up hugely on the windows. As the whole design of a steel boat leads to temp differences and the UK has high humidity. More so at water level of course.

The issue is the condensation then runs down from the windows along the wooden panels inside the boat. Doing huge damage over the years. One of the big reason owning a boat is costly. There is constant maintainance and replacement work. Im good at the electrics. But my younger brother dose most of the woodwork.

A common solution is to have a desiccant container with a water catcher below it positioned near the windows. This effectively absorbs some of the humidity before in condensates on the windows. Then, as the Desiccant overloads, releases it into the catcher.

You then need to empty the catcher and replace/dry the desiccant often. And honestly, it still just reduces the issue.

You can buy holders to do his. Sold for boats and caravans etc. But honestly they tend to be a bit universal, so not actually very usable.

Part of me thinks I can design a 3 part system that can be mounted. Have a drip pipe leading directly to the bilge rather than running down the walls. Then have slot in desiccant units that can be carried home and back and microwaved as we swap over.
