\"\"<\/a>Before I get into this next post, let me mention that I’ll be exhibiting again<\/A> this year at Makerfaire NY 2013! I’m booth #10895. It’s on September 21st and 22nd. I’ll be at the 3D Printer Village. I hope to see you there! For those who don’t remember it, here was my post last year about my Makerfaire NY 2012 experience: Makerfaire NY 2012: Booth 8736 (My RepRap!)<\/A>. <\/p>\n

Still trying to catch up on the blog. Yes I know how absurd it is that I’m talking about past events (from over a year ago) in the order that they happened, hoping to “catch up” like getting out of debt. I don’t care that it’s absurd. \ud83d\ude42 But want to know how absurd it is? The link I just gave above about last year’s<\/I> Makerfaire (2012) is AFTER the events I’m describing here, yet I blogged about it because Makerfaire was cool enough to blog about out-of-sequence, and I’m now just getting close to catching up to that point (which I’ll then not cover, since I already did), and then in the present I’ll actually go to the 2013 one! That’s in 4 weeks from today, so I’d like to catch up before that if I can. What a byzantine mess!<\/p>\n

Ok. Today is August 28th 2013 and I’m describing events from April 3rd of 2012. Here we go.<\/p>\n

The next thing I just HAD to print was a quadcopter.<\/p>\n

At work they had let us borrow a quadcopter (an AscTec Pelican) and it was incredibly fun. Two coworkers of mine (Reed and Neil) borrowed it with me, and we flew it enough to get a serious taste for it. I wanted to print one.<\/p>\n

I decided to print the PL1Q Vampire (thing:17612), but with a bunch of alternate parts.<\/p>\n

First I tried printing the regular center piece (“body”). That has some really challenging bridging, and I wasn’t using a fan. I didn’t have much luck.<\/p>\n

I’m not completely sure on the order of these, but the first (aborted) fail I had (according to image number) was this:<\/p>\n

\"\"<\/a><\/p>\n

Then I printed a bridging stress-test piece, thing:9804 (I still didn’t have a fan):<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

I also briefly tried a filament guide clip (thing:20663) on the center of the bar (which I later stopped using):<\/p>\n

\"\"<\/a><\/p>\n

Another failed attempt (which looks particularly messy – I must have left it unattended) was this one:<\/p>\n

\"\"<\/a><\/p>\n

So instead I printed this version from thing:18106 which split the top and bottom parts into two pieces.<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Here they are together (I didn’t break off the circular pads that were only there to hold it down on the bed yet):<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Next up were the arms. I couldn’t print them vertically, so I found this variant (thing:17803) that printed them on their sides:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

I printed 3 more arms, and put them all on for show:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Then I printed one of the most solid, serious, strong looking pieces I could remember printing on my RepRap – the dome from thing:18106 (pl1qvampiredome_fixed.stl):<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Here it is placed over the rims of the arms, holding them in place:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

…and here’s what that looks like from below:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

Next I printed the landing feet, which I now realize were the only parts directly from the original thing:17612 model:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

The last parts were the combination motor-mounts-and-propeller-guards for each of the four arms. I used the ones from thing:18106. Here was the first one:<\/p>\n
