Build a model rail road table/ layout with a shelf under it to put the 3d printer. they really take up not much room... You can have BOTH

Yeh, build a small 'Mountain' to 'hide' the printer, would love to see the result

Yup, the mountain could be dual purpose; mountain and printer enclosure for better printing! (I have read many posts and watched videos that highly recommend enclosures to hold heat in thereby making it easier to print different materials.)

I just wanted to see how you were using the tubing. It doesn't have to be on a reef tank. I have 2 freshwater tanks myself, but I'm planning on repurposing my 125 gallon African cichlid tank into a reef tank over the next couple of years.

I have nothing "extra" set up on the FW as it's only 55 gallons. Just filtration and that's all. I do things the "old-fashioned" way with buckets and such. As a matter of fact, it's filled with fish that I would not necessarily have but, since it's for my wife, we have the fish she likes in it. Lots of fancy goldfish (oranda, telescope, black telescope/moor, shubunkin, Japanese Ryukin) mollies, loach, neon tetras, various small cats, plecostemus and, of course, glo-fish. I have a few small plants in amongst the decorations but they are slow growing since I have the wrong lighting on it but my wife likes it.

Cool!

Whoa
I’m torn between 3D printing or model railroad layout . Space is premium and I can’t have both

I had N gauge railroad stuff years ago and I loved it. I still have some of the engines and cars around here somewhere. It was amazing how much more stuff you can fit onto a 4x8 sheet of plywood with N gauge than you can with HO.

Fusion 360 is the way to go. They have some nice built in tutorials, and a ton of online videos to help you learn.

Been learning on FreeCad, started making progress this morning on how to use it. Fusion doesn't have a Linux version and I would hate to have to use my laptop to use a Windows version. I tried another called Blender but couldn't get it to load, probably because my video card isn't 3D compatible?

I have a Z gauge set that was my grandfather's. I pull it out from time to time and set it up for a few days.

Nice! Z gauge is tiny the engines are only about 2 1/2 inches long.

Curious , what happened ?

Nothing bad....loved it. Got an apex for black friday.

Yes it is. A 2X2 sheet of plywood is plenty of room!

That’s what in my mind as well . 2x2 , still thinking about track plan . Junior wants crossings . I want also lot of building/street lights, a construction site with some moving vehicles. I am not so particular about scale and replicating an real place/time .

I need some advice with plumbing. I am really novice on this.
I am struggling to setup my ro di unit (ro buddie ) in my apartment. The unit uses push connector and standard rodi tubing (ploythelene ?) and ships with connectors to connect it with garden hose (1 inch ?). As well as another connector for hooking it up with faucet .
My apartment has what I think 3/8 connectors. The patio does not have a garden hose like last time , so I don’t have a free 1” hose . My options are to set it up in kitchen or in one of the less used bathroom /vanity . I am thinking of either using a Y connector with valve to intercept an existing junction (like the one next to toilet or vanity ) or have an on demand faucet based connection . I need help with these questions: did i guess the specs right ? The approaches are ok ?
I had a hard time finding y connector with valves that are threaded and 3/8. I had equally hard time removing the aerator from our faucet , it has what I think a coin slot aerator . And I was only able to remove two of the overall 3 components. The last one I could not and get I am not able attach then rodi units connector with that part in place :-(
Suggestions?

Get one T adapter 3/8 to 3/8 male
get one Shut off valve 3/8 to what ever your ro line adapter is .. i think that is 5/8 (take with you to match up )
1 Short 3/8 to 3/8 Water line .
Turn off the water and Remove that water line. Install the new short 3/8 line .
Install the removed line to the end of the 3/8 t adapter
Install the new valve on the other side of the t adapter..
install your supply line to rodi unit adapter to the out side of the newly installed valve.
You can now turn the Rodi on and off without messing with the sink aerator .

You can also get a Glue on saddle valve for the drain under the sink.

Hope this helps. Those spigot adapters in your image above are a flood waiting to happen from my Experience ..

I’d install it right after the faucet valve myself. I’m horrible at guessing plumbing sizes but you’re looking at either a 1/4 or 3/8 _compression_ fitting. You’d want a T to split to another two fittings, and assemble from there.

Note that compression threads are a different size than NPT pipe, so adapt accordingly.

Any reason you need the fitting to have the valve instead of using a 1/4 valve?

Exactly ..Those supply lines are almost always 3/8 and that spigot adapter is either 5/8 -3/4 sometimes 7/8 that is why i suggest taking the pictures and part with him to the hardware store.. its Super easy to have it hard plumbed with much less risk of leaking...

This is what i do for a living.. AWESOME Work on this project thank you for joining in ..

Insurance claim waiting to happen. The water needs to disconnect from a threaded metal mechanical part. The water pressure can be as much as 80 psi . these plastic parts, Compression fittings will Leak. I cant wait until plumbing codes catch up and BAN any and all Compression fittings
But until then i will keep making money on repairing the damage they cause when they leak

I always end up buying about three different size assemblies and returning two [emoji854]

Agree on the hard plumbing. For the same purpose, use pressure rated (labeled for ice maker use) tubing on the inlets to the RODI.

All of my filter stack sits in the garage. The manifold of my cheap RODI bought back in like 2004 gave out a few years ago - high pressure water jets while I was out traveling are suboptimal. But it’s just unfinished garage drywall in the end, and a dry hot summer limited damage.
