I love teaching, 3d printing, and blowing stuff up. Hopefully not all at once...

Do I have any friends that work with video game design? My robotics team won our regional qualifier and would like to speak with an expert about a project they are working on.

Imagine a school where your classes support your weaknesses by focusing on your strengths. Robotics classes where you learn a foreign language. PE where you learn calculus while training like an astronaut for your science class. Crazy idea, huh?

Student brought in a printer for me to help fix. Printing a vase and am noticing slight overextension at one point during each layer. It's spiralized and the same g code is fine on my printer. Any thoughts?

Consistent overextension in solid layers to me means my e-steps are off
Is anyone doing the #BreakTheCode2 challenge? I could use some help from my friends. Here is the link to join my "crew" Https://btc2.tech/WDXoTt

First attempt at 3d printed gears. Any tips? Mocked up quickly in tinkercad. Designed them to fit @LEGO_Group technic beams. Struggling with tooth count, spacing, hub size, tooth dimensions and shape... Still kinda works, though...

My student council asked me to 3d print some trophies for spirit week dress up days. Any ideas? Pajama day Future day Crazy sick day Spirit day (we are the eagles)
I want to create a digital bulletin board at my school, that would have no audio. I want people to be able to access the audio of videos playing with their phone. Any ideas how this could be possible?

Anybody know a place I can get some cheap plastic sheets for vacuum forming?
I need opinions. What is the best material to print gears using a Bowden system without an all metal hotend, assuming that PTFE degrades at around 240C? @__THON @MakeItWithCal @3DPProfessor @JoshGotBored1 @JShawsTidbits @alienslacker plus anyone else who would like to chime in

Any of my friends know about VPN's? There is an app for my diabetic glucose monitor that's only available in Canada. Is there a work around for this? Is something like that legal?

I know I don't have a far reach on here, but there are many of you that, even without knowing, are great examples of how a father should be. You are great examples to me. Thank you for showing your kids how to act right. Happy #FathersDay

Went to the @Crayola experience in Phoenix, and just had to make a custom crayon.

I have had several motors go out in my robotics class this year, and @LEGO_Group awesomely replaced them for me. What should I do with them now? If I took them apart, the actual motors still work, it's the gears and sensors that stopped working.
