3D Printing: Not Just For Do-Dads Anymore PART 3 – WDTV

wdtv 3d printed bracketThere’s a new TV setup at the Bremster household. Flat screen on the wall with no visible wires. There’s one problem though, my WDTV media player. It’s small but still a tad too awkward to be precariously balanced on the top of the TV. Plus, the power, ethernet and HDMI cords sticking out the back don’t let the media player stay aligned with the TV. So what’s a dude to do? Design and 3D print a sweet bracket of course.

How to Hob a Bolt (with a Tap & Milling Machine)

wade extruder diagramWith the Wade-style RepRap 3D Printer extruders, the part that actually drives the filament is a ‘hobbed bolt’. A hobbed bolt has a little toothed-groove around its circumference that grips the filament and drives it into the hot-end as the bolt is turned. There’s a few ways to make a hobbed bolt. We’ll show you one way here that utilizes a Tap and Milling Machine.

For a typical Wade-style extruder, an 8mm bolt is used. Since we want to cut the toothed groove completely around the bolt we need that bolt to rotate. What better way to do that than to mount it in a pair of bearings. Regular skate bearings (608zz) have 8mm inner diameters and are actually what are used to support the bolt in the Wade extruder. I designed up a quick 3D-printed bracket to hold a pair of bearings and provide some features for easy clamping in the Milling Machine’s vise.  Continue reading

3D Printing: Not Just For Do-Dads Anymore

SA-HT750 Speaker Stand CouplingA pet peeve of mine is all the do-dads and nicknacks printed with 3D Printers. Sure, it’s fun to get going with your printer quickly but I think the non-functional printed trinkets get way too much attention. So what’s a good use for 3D Printers then? How about fixing stuff around the house? One example is a window latch in my house broke. I could only imagine getting a replacement from the window company would be all but impossible. So, I took the broken pieces and designed a replacement. It’s been a couple years and that latch is still latching well. It cost me just a few minutes of time and I got it the same day. That’s a win-win. Continue reading

CT Hackerspace wins the 2014 “LulzBot Hackerspace Giveaway”

LulzBot-MiniMany members in our community recognize the full value in what open source can mean with a direct correlation to innovation. We are very excited to see that Lulzbot recognizes our commitment to open source by choosing CT Hackerspace as a winner to their 3D printer giveaway contest . We look forward to working with a community with innovation at the core of their “open” philosophy. The Lulzbot Mini 3D printer will be a great tool to have in pursuing future inventions and creations by both our members and our surrounding community.

UPDATE: Our printer worked right out of the box. The heated build platform and automatic bed probing works excellent. This printer is a real workhorse. Check out our dedicated Lulzbot work station, it’s always ready to rock and roll:
