My father and I turned our garage into a cinema room for the cost of a cheap Chinese projector (£180) and screen (£20), for surround sound we used an old 5.1 speaker set we had up in the attic. We’d lost/thrown out the brackets but found this pretty good design by MaximSachs on Thingiverse (http://www.thingiverse.com/thing:292822), printed them in White ABS on fast and with 0.20mm resolution height. Delighted with the results, they took just shy of 30 mins each to print and the tolerances of the slide is spot on. To me this is the best application for 3D Printing.

Just a bit of laminate flooring.
3D printers for making brackets I have to agree it’s one of the best uses. It’s so universal

@Mr_covert I noticed a guy further down making new plastic stoppers for his chair. It just, to me, seem like the perfect application for current gen 3D printers. Could you imagine if Ikea opened up a repository of spare part files? They wouldn’t have to make, store or ship parts, how much theoretically could that save them? And on the flip-side would the bottom fall out of an entire industry that produces spare parts?
Great solution! I have speakers that need to be hung but I haven’t wanted to spend the money on expensive factory made brackets.
That guy would be me 
Hammered in the other three this morning and have been using the chair on and off all day. Better contact with the floor than the ones they replaced, nice tight fit so far less chance of movement, wear and breakage. And pennies to make.
Which DLP did you go for an how many lumens do you get out of it?
P.S. you’ve got some odd word breaks in your blog text.
