FWIW, the easiest way to find out if somebody has made (or has tried
to make) replacement parts for anything that can be 3D-printed is to
go to thingiverse.com with your web browser.
And then search for whatever thing you need (search terms / words are
a separate subject, try as wide or as many as have time for.
When you find a part, look at pictures, comments, makes and so on to
try to figure out if this is a working part or just something somebody
has mad a 3D model of, and never tested.
Some relevant examples:

Are the files ?platform independent?? I know very little about 3D printing, but have been
tempted to get a printer for a while now. Though I?m worried about what my kids wanting

Typically the files on Thingiverse are .STL format, which is portable 3D
model. One feeds it into a slicer program (there are several to choose
from) to produce GCode that uses the specifications of one's particular
printer so that the right GCode gets spit out.

If you are seriously considering getting one, consider:
https://www.woot.com/category/computers?ref=w_gh_cp_5
That offer is for 24 hours!
Woot is now an Amazon company; free shipping if you log in with Amazon
Prime, otherwise, the shipping is $6
Amazon sells filament for them.
Ender3 is apparently open source design, manufactured by numerous
companies, some with enhancements.
Can operate stand-alone from STL files on Micro-SD card.
Assembly required.

Just be aware that you get what you pay for. If anyone here would like to
get into 3D printing, I'd recommend one of two different printers:
If you want a boring "cartesian", get a genuine Prusa i3 Mk3 from Prusa
Research. If however, you want an amazing, fast, and sexy machine, get a
Rostock MAX v3.2 or an Artemis 300 from SeeMeCNC. It's a "delta"
configuration machine. Women will want you, men will want to BE you. (or
vice versa, YMMV) ;)

Gene, you're just sore that the $175 ender 3 is comparable to a Prusa i3 Mk3 that
costs $800 (those words are from the all3dp.com reviews, not me) ;) Actually, I think
you're spot on when you say it's not newbie-friendly because it requires some
tinkering once it's out of the box to get great results. Another side of that is that
perhaps it's the newbies that really SHOULD spend the time tinkering to get it right,
so they understand what to do when their other 3d printers go awry. I suspect most of the
people here are the tinkering type ;)
Actually I misspoke when I said the ender 3 has design flaws. All of its flaws are in the
execution of manufacturing, not in the design itself. Replace the extruder with an
all-metal one instead of plastic (the plastic one cracked in a few weeks for me, so
filament slippage) - cost is about $15. Drop in a borosilicate glass bed, so you can get
better adhesion than the stock pad, easier removal, as well as more flexible choice of
filament materials - that's about $20. Replace the z-axis rod coupler with one that
actually doesn't slip - cost about $5. And while not necessary, it makes it a lot
easier to get good parts if you add an automatic bed leveler - $70 (for the th3d one).

I'm not sore at all. Out of the 12 printers I have, only one is a dirty
little bed-flinger. ;) I recommended the original Prusa because it's a
good design (for a dirty little bed flinger), it's a reasonably affordable
choice if you can't join the Delta Hegemony, and it's newbie friendly. :)
For Emmanuel's(sp?) case, the Ender 3 is a great choice because he's not
going to print with it, he's just going to use it as a motion gantry for a
CNC controlled microfiche imager. If I had the time (and a stack of
fiche), I'd probably buy one for that purpose myself.

These guys were at MRRF (Midwest RepRap Festival - if you're interested in
3D printing, you MUST go! It's a free event) last year or the year
before. Nice bunch. The company name is pronounced the same way you'd
say "CNC" (SeeEnSee) :)
