UPS for 3D printing through voltage sag/brown outs?

Hi all. Just wondering if anyone has any thoughts on uninterruptible power supplies for home 3D printing. Obviously, any reasonably priced UPS isn’t going to keep a 3D printer going through a long print. Or even a short print, really… But wouldn’t it be nice to not lose an entire print to a momentary dip in mains voltage? That’s what I’ve been thinking, anyway, so the requirements would be:Good voltage sag (and maybe surge) protection..reasonable size (to go with a desktop printer)Inexpensive. Commercial solutions are a whole different topic!Maybe 1 minute battery time. It would take a serious unit to ride out an outage or long brownout, so let’s just say “long enough for a generator to kick on”. Or not, because not everyone has a generator.So, thoughts? http://ift.tt/2asAO0O

My DIY Partially 3D Printed Home Network Equip Rack

So I was building a network rack since I am going to wire my home with Gigabit Ether (tired of wireless). Half way through the construction I had to stop myself. I was building the rack using the old way of thinking….hardware store, nuts & bolts. It was time to employ my new method of thinking about solutions to problems since I’m now a “maker”, I suppose.The rackThe wood was already cut and the frame already bolted together when I decided to employ my new capabilities. The brackets were designed around that fact. I don’t have precision wood working tools so my cuts are a little sloppy and so is my hole drilling. Ironically, the 3D printed brackets gave the rack a cleaner look than I could ever make it. A few 1/2″ wood screws later and the frame is sturdy.I still need to fasten some boards to mount my cable modem and wifi router. I think I’ll design brackets for that. I’m definitely going to design a wall mount bracket that will be adjustable so that you can wall mount this to studs. And when I get the cable ran I’ll print some items to mount to the frame to make sure the cables are neat. The design needs some tweaking (hindsight), but once I’m done I’ll make the collection available on thingiverse. http://ift.tt/2a7yekb

Best technique for smoothing prints? (specific details in post)

I recently printed a small skull and would like to display it on my desk. It’s actually fairly smooth and looks nice from a distance, but I would like it to still be nice when held. Currently I’m thinking something simple like this would be my best bet. It looks like it gives it a good texture and I like the shiny appearance it gives. My only concern is that the prints still have the layered, printed appearance and I’m wondering if there’s anyway to get rid of that. Perhaps adding white dye to the mix? Does anyone have experience with this? http://ift.tt/2amtDI3
