My teeth are crooked. My right central incisor is pushed inwards, while my right lateral incisor (right next to it) projects outward. I had braces when I was a teenager, but since then these two teeth have drifted in opposite directions, about 2-3 mm. I don't have money for braces again. All my other teeth are still in their correct locations, it's just these two.
I have a 3d printer. I'm going to 3d print my own "invisalign."
1. Make a mold of my teeth.
2. 3d scan the molded resin..
3. Create a 3d model of my palate, with each tooth as a separate moveable object.
4. I'm going to create a set of 20 or so 3d prints of my teeth, in the positions interpolated between their current position.
5. I'm going to use Shapelock/instamorph thermoplastic to make a smooth invisalign-style retainer for each of the 3d prints.
Since only 2 of my teeth are out of alignment, I will be anchoring the retainers on the other teeth.
I have the 3d modeling/scanning skills required, and I have the 3d printing capability. I don't know about molding. How do I make an impression/mold of my teeth for the initial 3d scan? Whats a good cheap pourable plastic or resin for this initial impression?
Also, does anyone on here have any orthodontic knowledge? I need to know more about the time frame for teeth movement, to determine how often to switch retainers and how much movement to plan out for each retainer. Should the movement be linear over time, or does it need a period of initial acceleration?
I considered 3d printing the retainers, but I think Shapelock will be better because it's smoother than PLA, more flexible, and potentially less toxic (and definitely less toxic than ABS).

I am looking for an impact driver with a few peculiar requirements.
1) The ability to turn off the "impact" portion of the driver (not sure what this feature is called). So far, I am not very good at the impact part and may never be, due to some light motor control damage I have. I can do better work if I can go slowly.
2) I would much, much prefer low-RPM to high-RPM, with much "room" at the low end. I predrill pilot holes, so torque is rarely an issue. I continually come across the problem of the driver "zooming away" from me too quickly, heading up towards high RPMs, then driving the screw more deeply than I wanted, faster than I wanted, sometimes causing cracking (even with countersunk holes) and exacerbating the issue of me maintaining a firm enough contact for the high-speed "impact" portion, leading to the usual BR-R-R-R-R-R-RT issues as I screw that up once more.
3) Corded, not cordless. I am irregular about changing my batteries and in any case, I am never far from a wall socket. I do not want to deal with a battery "going bad" and then having to hunt for a new one when I now suddenly need to use my tool. I know a lot of people love cordless tools for their manueverability and portability, but that is not a concern for me.
4) I will gladly spend three times the money on a tool which will last me four times as long. Reliability is more important to me than price.
Do you have any you would recommend based on your experience? Thanks.
/diy/ career changes - certifications?

tldr: Independent education and the results it brought you + technology education thread
I don't want to make this into a blog post, I got out of a factory this summer and decided to work toward Cisco certifications. My degree's in history and this route became a lot more appealing than going back for a masters.
I know there were some networking friends arguing about the guy who had to build a shed to get internet set up on his property. Are any of you certified? Otherwise self-taught? A relevant degree?
I'm excited about getting into this and hoping to get the CCENT within the next month or two, and follow up with the CCNA and probably CCNA Security over the months after that.
Getting CCNP and CCDP sounds good too. I figure my perspective might change a little by the time I finish those first few, and might feel like going for something like the LPIC, maybe more security-focused stuff, or maybe something like Nagios or other monitoring that Cisco doesn't cover as much. But maybe I'll be unemployable until I get through the CCNP and should stick toward that before thinking about spreading around.
Whether you think certifications are a stroke, or any of them seemed to help out or become a waste of time, I'm interested

I moved out a few weeks ago, renting a house together with a friend/colleague. Earlier this week I cleaned out the shed, his dad (who we're renting from) left behind some stuff, amongst it a really old oak workbench. It's sturdy as fuck, so I moved it inside, we actually live on the first floor, and I get to use the large room on the backside ground floor to set up a little hobby room. His dad had a workspace there making shoes and prosthetics, it has a lot of light and power sockets all around, even a 380V outlet.
Now, I just do little projects every now and then, building basic things and learning basic skills, so I don't need top of the line tools or anything. I usually buy my tools in those over9000-piece sets of whatever I need at the moment, and replace what I break or wear out (so what I actually use a lot) with higher quality items.
So, what I'm here for: I have a range of common tools, but one thing I have a lot of trouble with is drilling and cutting straight, so I was planning to buy a cheap drill press and band saw. I visited a small local shop, and they had "Silverline" brand models, which would cost me less then €200 for the 2 machines combined.
Is this brand ok for very occasional use, or is it total shit that I will regret buying after using it once or twice?
I also now realize I typed up a whole story that has almost fuckall to do with my question, but I'm gonna leave it there anyway.
Thanks in advance!
