Luckily, she never attempt to touch the heated bed and hotend, don't know why, only interested in mess with the console. May be the beep sound feed back is what tracked her. Now all printer in attics and they are safe now.

Sell me the sd3 heartless?? Haha

IMHO the SD frames are not that solid . you would be better off building one from angle or  20/20, 30 /30.

Or maybe you be the good parent and start teaching your child to keep hands off of things that don't belong to them.

Not that difficult  but you do need to be smarter than the 2 year old LOL

You need to start when they are young not wait till the are 20.

We really do need to get back on topic.

I have no issue to fit these printer, but my baby girl learned to walk over the last year, and printer with touch screen is her favorite toy because machine beeps and change display when get touched at right spot. Also those printer with rotary encoder push button next to the display also fun to play with, MonoPrice V2 and Creality printer have similar design. She have paused my printer 10+ times but have not yet canceled a print so far, which is good news.

So put printer in living room/bed room is no longer an option, have to keep printer in basement and attic. Most of my printer are under $100, but shipping will cost $40+, really not worth of my time to list them on ebay and drive to post office at working hours.

Or maybe you be the good parent and start teaching your child to keep hands off of things that don't belong to them. Too many kids now days don't know this simple lesson. But then again I was raised by an older generation.

Where there is a will there is a way. You can have many printers in little space, it just depends on the amount of work you wish to contribute. The attic or basement would just be a waste since it cannot be temperature controlled unless they are finished attics or basements.

Even a machine with an enclosure would have a hard time in a cool damp basement and in the summer the heat would be murder on the electronics and motors in the attic.

This is indeed an expensive hobby, I have to buy a house with attic and basement in Boston area to fit all my printer

That is not a hobby that is an addiction .
Carl is correct with shelving  and power adapter one should be able to set up 10 to 20 printers in a single room.
And at $150 to get stated  IMHO this is not an expensive hobby.

You know there comes a time when you need to ask yourself if you have too many printers and why you need so many? If you need them to keep of with demand then you should just get what you need and make room for them. If you are getting them just to get them then you need to decide when enough is enough. Or sell the ones you have had experience with to make room for new ones you want to learn.

If you are doing this for a hobby then you really only need one or two at most. If you are doing it for a living then you will need many to make it profitable. Then you should consider renting a small building to put them in like many print farms do. If you are doing this for some extra income then you could probably get by with four or five units.

Then it come down to utilizing space efficiently. Get or make selves on one wall and put the printers on those shelves. On a six foot shelf you could put two to three printers easily. Then make the shelves from floor to ceiling with 3 foot spacing you could do three rows, possibly four if your machine are small format. So that is nine to twelve machines in a 6 by 10 area. Even a shelf that is 6 by 6 with two rows will hold 6 machines.

But then again it all comes down to what do you need, not what do you want.

LOL, it is nothing but a damaged frame at this point.. all the internal parts have been stripped out

it was pretty heavily dented in shipping.. destroyed the controller board, and but a nice dent in the rear & the corner closest to where the board was mounted... not worth trying to salvage at this point.

Sorry, but you do not "have" to do anything.. you might choose to do so, but you do not have to.

Well considered and useful advice as always Heartless!

I just thought the OP might find that project interesting. There is a BOM for the project and 3 completed makes.

With 4 FDM printers in my print room, I've got enough spare parts and leftovers to build another printer but no place to put it once built.

yeah, i have plenty of bits & pieces here as well..
I have sold or traded off 2 of the kit printers, but the FT-5 remains.. have three of the Solidoodle 4s now, and the PrintIt Industries Horizon... for a total of 5 "functional" printers.. plus the carcass of an SD3 that was damaged in shipping, and most of the parts of another kossel kit that was a poor investment (don't buy cheap chinese crap!)

I need to do a bit of reorganizing to get the 3rd SD4 in the lineup, tho, so I can completely understand the lack of space.... one of these days.
