I just had an idea for a mini-business!
I think there are enough interesting things on Thingiverse that a MakerBot/RepRap operator could make a little bit of money printing some Thingiverse models for a fee.

More stolen content???
This time I blame DaveDurant. As you can plainly see from his opening blog post, he freely admits that he is TAKING the content that was being published HERE quite regularly and putting up on his OWN site!!!
For shame, DaveDurant, for shame.
Kidding aside, Dave just published some great stuff about his MakerBot high resolution printing record and Skeinforge Support.

Yes, I will fix your computer
Tech Support Cheat Sheet
I have a rule for all of my friends. I will fix their computers for free, twice. :)
It’s a good rule and it has helped my friends and myself on many an occasion. Contrary to the impressions of those unfamiliar with the inner workings of their own computers, diagnosing and fixing a computer problem is not a matter of innate knowledge. It’s basically 50% making common sense interpretations of errors and common sense changes to settings and 50% Googling for the answer.
Given fixing computers can be tremendously time consuming, WHY would I spend my free time fixing them for free? Simple. My rule is, I’ll fix your computer twice. First time, you give me your broke down computer and I get the OS working, repair whatever it is, and give it back to you good as new(ish) and if there’s a problem with it again, you give it to me to fix again. Second time, you give me your broke down computer and I get the OS working, repair whatever it is, and I keep it.
Oh, and if you want to know why you should never help someone with their computer problems unless it is really dire, check out this Dilbert comic.

This 3x2x1 Rubik's Cube could be yours!!!
I’ve printed up this 3x2x1 Rubik’s puzzle cube, but I’m looking to improve it. The colored sides consist of little bits of nearly-square paper I colored with crayons and glued onto the cube surfaces. If you wanted to improve it you could just peel them off, sand them down a little, and apply better looking stickers. It’s not without it’s flaws, but it is functional. 1
I’d like to try a little experiment and see if anyone wants to buy this prototype off me. I don’t want to spend the time to set up an Etsy account, eBay auction, or any other of the variants out there. So, is anyone interested in buying this first draft?
If you’re interested, please leave a “bid” in the comments. I’ll ship anywhere in the U.S. for $2.00. Highest bidder at the end of seven days from now will be the proud owner of this one-of-a-kind item.
Edit: Payment via PayPal, please!
Update: 8/4/2010 a top bid of $10!
- It is a first draft/prototype after all. [↩]
Revising the 3x2x1 Rubik’s “Cube”
3x2x1 Rubik's Cube
I finally found the time to print a copy of my 3x2x1 Rubik’s Cube. Having printed it, I’d make a number of improvements in the next design iteration. I would:
- Make the circular slots in the center cubes smaller or the circular tabs in the four outside cubes larger.
- Enlargen the holes for the nut and bolt.
- Make these cubes solid so that they slide against each other easier.1
- Consider replacing the entire nut/bolt requirement with a connection similar to the becco block connectors. This would make for a totally printable solution.
- Print the cubes two at a time to minimize warping without a heated build platform.
It slides reasonably well and is certainly functional. However, after several center cube rotations I will tighten the center bolt.2
MakerBot Toy Repair
I had previously fixed a toy fire truck by modeling a broken swivel and printing a new one.
Today I discovered a handle had broken off a magnetic drawing toy. The yellow handle is hollow and separate from the red plastic body. It is held in place by plastic tabs that slot into body and protrude into the handle. The plastic tabs that held the handle in place were themselves hollow – and cracked right where the handle met the body.
I measured the broken part, modeled it in Sketchup, duplicated it, exported to an STL, put through the brand new RepG, printed, opened the toy, inserted the printed parts, put it back together, and DONE. Since the printed tabs are on the inside, it is functionally perfect and cosmetically indistinguishable with an off-the-shelf model.
Without a MakerBot, it would have been either cosmetically unsightly or prohibitively expensive to repair. Win.
Long week
It’s been a long week and I’ve been very very glad of this weekend. Unfortunately, a big fat chunk of this Saturday was also devoted to work-like stuff. I didn’t get a chance to design or print much this month.
Once I get some time, I’d really like to get a MakerBot heated build platform. The only problem is they’ve been out of their SMT kit for a while now. And, without the SMT kit, I can’t assemble the HBP kit, so I won’t need the new relay kit.
Should I pace myself?
This blog is as much for me as it is for anyone else. 1 When something occurs to me, I type it up and click “Publish.” However, this means I’ll go days without a single post and then have a flurry of half a dozen posts. Some of my posts languish in draft form, half-notes, jottings of ideas, etc. 2
Help me out here. What’s better – if I pace my posts – say one a day – or just have them published as they occur to me with random gaps?
As a loyal reader, what do you prefer? Come now, both of you can chime in. <crickets> Bueller?
A MakerBot Cart – like this!
Now, THIS is a MakerBot Cart
This is a picture of Mattpr’s setup. 1 This is an incredibly great setup for a MakerBot Cart. Indeed, it’s the sort of thing I dream about.
FYI, Matt – it took me longer than I care to admit to get your “my all Rush mix tape” joke. Me, a guy who named his MakerBot “Bender.” I may have to bite my own shiny metal ass.2
- Dude – you’ve got an all rights reserved license on your Flickr page. If you wish, I’ll take out the picture – just let me know. [↩]
- Interesting side note about my ‘bot in case anyone is keeping score at home – I painted the underside of my MakerBot silver. This way it has a shiny metal assplate. [↩]
ADD and TLDR
This post could easily have been titled “inverse relationship.”1
I tend to think I’ve got a form of ADD. It’s better than saying I’m impulsive, excitable, or impatient, right? In any case, I read and blogged about Capolight’s post on creating models from images without reading the entire thing.
The Google Sketchup instructional video he included in his post was great. Basically, it helps one create an object from a photo with some kinda fancy Google UI stuff. I wish I had known about that a lot earlier. :) What a cool feature!
I suppose I could have titled this “RTFM” too…
- As in when you have ADD you won’t read anything and everything is TLDR… [↩]
