Now that I’ve got the process for creating a cookie cutter design file, it goes pretty quickly. Unlike several of recent designs (Dalek, sonic screwdriver, etc), this design is fairly simple. The STL output from the Sketchup plugin didn’t even need any cleaning up/repairing.
In any case, share and enjoy this TARDIS cookie cutter.
Those of you who are not fans of Doctor Who may want to just skip this post.
In any case, what I’d really like to do is to design and print a life-size model of a sonic screwdriver. Ideally it would have a spot for inserting an LED, space for a battery, switch, and be able to extend just as the one in the TV show.
Until then, here’s a sonic screwdriver cookie cutter.
SWEET. I’ve been so busy of late123 that I haven’t even been able to print several of the things I’ve uploaded. I’ve uploaded several cookie cutters, with another sitting on my hard drive and one more knocking about in my head keeping the cobwebs company. I’ve also uploaded my variation on a simplified Rubik’s cube.
Well, someone printed it! It looks AMAZING! I wonder if it works properly? I slapped the design together rather hastily after getting frustrated with my MakerBot failing to print TomZ’s 1x2x3 Rubik’s cube.4
I can’t wait to either get some feedback from Lotu (who printed it) or print up one of my own so I can improve on the design. I’d really like to make a version that is 100% printed – with a snap joint in the middle rather than a nut/bolt system. If I go down that route, I was thinking about incorporating what I learned from the fantastic Becco blocks connection system by r3becca.
If you print one of these, please answer the following questions:
Cyrozap‘s recent vociferous comments about truncated feeds were basically on point.
He noticed that I had recently changed my RSS feed settings to serve up truncated posts, rather than full content. I made this change in mostly because I was tired of dealing with content theft. However, I’m reasonably sure this will probably not be an issue any longer. While the points made by those articles are certainly valid, I would point out that it is far easier to steal content from an RSS feed than it is to write a content scraper. Having written both, once upon a time, I can attest to this from experience. Truncated feeds may not be a deterrent to all – but it will deter those who are just using a WordPress plugin to suck down RSS content.
In any case, I left the RSS feed settings as they were – due to inertia and because I assumed no one would really notice. But, since I haven’t had to deal with stolen content in a little while and at least one person prefers un-truncated feeds… the long rambling RSS posts are back!
If you find my rambling babbling showing up in your RSS feed, well, you have Cryozap Cyrozap to thank. :)
I just read Nophead’s post about his Mendel making its 18th child.
First off, that’s an incredible feat. Even under the best circumstances, the print time and amount of human intervention required of a Mendel as it builds the parts for replication is still considerable. Eighteen more RepRaps in the world because of his hard work and determination.
Reading about his RepRap working on it’s 18th child, I just couldn’t help thinking about the Duggars.
I’ve uploaded my designs for a Dalek cookie cutter to Thingiverse.
I don’t even eat that many cookies. It’s just that these are just fun to design. I realize there’s an SCAD Thing on Thingiverse for creating cookie cutters. However, I’m just not familiar with SCAD and Sketchup with a few key STL plugins is SOOO easy to use.
My design process is essentially:
I’ve posted a few times about useful Sketchup plugins, so if you’re getting started with Sketchup and MakerBot that’s a good place to start.
I must admit, until very recently I was completely unaware of the plight of the soft-pawed albino stoat of Southern Wales.
The story of these gentle weasels is a sad one indeed. Once these stoats roamed the great plains of the Serengeti in herds so vast the sound of their collective padded footsteps was deafening.
But, highly prized and sought after for their sweet sweet tears these animals were hunted to the brink of extinction. Even in this modern age there is a brisk underground black market trade for sad stoats. Now, this once ubiquitous creature has been moved to the endangered species watch list by the combined efforts of a pharamecutical industry bent upon creating ever more potent drugs for keeping these animals on the brink of despair and a growing demand for stoat tacos fueled by a surge in molecular gastronomy.
If not for the Great Stoat Conservatory in South Wales, the soft-pawed albino Stoat would have all but vanished from the face of the Earth. Here at GSCSW these ermines are protected from poachers where it is hoped their numbers may recover… in time.
Thank you to DaveD for bringing my attention to this fascinating mammal.
So, please take the time to make some of these delicious stoat cookies and remind your friends to save the stoat and eat a goat.
DaveD for his copy of my llama cookie cutter! Hooray!
Two days ago the universe was llama cookie cutter-less.
Today there are two in existence! (Well, three if you count my sub-par first attempt. It’s okay, but the walls are too thin and the cookie cutter is twice as tall).
The last week has been a fruitful one for me, at least as far as printing things on my MakerBot is concerned. I’ve designed, created derivatives, printed upgrades, updated the firmware, installed the latest (super sweet!) RepG, and even performed some maintenance.
One amusing and useful experiment was the serial production of the Z Axis Wobble Reducers by MakiYoshida. Using my current settings I printed one. Then I installed it and printed a second. The second was a visibly better product. I installed the second and printed a third. The third was no better than the second. I installed the third and printed a fourth. I then installed the fourth… and didn’t bother to print with it.
Right now I have two of these wobble reducers installed on the front right and back left Z axes. Installing one on the most warped rod (front right, for those of you playing at home) helped significantly. Installing the second on the back left helped a little more. Installing the third on the back right didn’t seem to make much of a difference, and may have been worse than the second print. I didn’t realize why until I tried to install the fourth Z axis wobble reducer.
Once all of the wobble reducers were in place I found that the entire Z stage was too mobile – and would easily shift from left to right and back and forth. When you have no wobble reducers one or more warped Z axis rods will force the entire stage out of whack. When you have four wobble reducers, there is nothing keeping the Z stage steady. Thus, the optimum number is between one and three. However, I noticed that having two diagonally across from one another gave me enough wobble reduction to improve the print, but not so much flexibility that it could get pushed around in the middle of a print.
Part of the problem is that this particular wobble reducer will allow nearly unimpeded side-to-side motion. However, these wobble reducers are also fantastic at compensating for a badly warped rod. I suspect that mixing different kinds of wobble reducers might be my best bet. I’m not really that interested in installing one of versions that requires precision rods, since it’s just one more thing I have to source for my MakerBot. Ideally I can mix and match these two types of wobble reducers to improve the overall print. The Z-axis floating arrester appears to keep the captive nut more … captive than the Z axis wobble reducers I have installed. This may provide the exact combination of rigidity and flexibility I need to optimize my print quality and minimize layer shift as I print.
The upshot of all of this, and the reason for the post title, is that I now have two Z Axis Wobble Reducers by MakiYoshida that I’m not using. Do you need one or two of these and feel like saving yourself the print time? If so, drop me a line.
Adam, if you read this – the latest RepG is AMAZING. Getting to preview an STL, convert to GCode, and then to an S3G file all from the comfort of the friendly RepG UI is fantastic!
It’s not that I’m scared of the Skeinforge UI or anything.
It’s just that it stalks me while I sleep, steals my happy innocent dreams, and replaces them with a theater of shadow puppet parade of horrors.
