Car accessory warped two weeks after being printed

So I made this accessory to add an USB charging port in my car. We printed it using PLA and everything went pretty okay. I installed it on my car and after a couple of days it started warping due to the heat inside the vehicle parked outside in the sun.What could I do to avoid this? http://ift.tt/2aUfnFo

Looking for your suggestions and help on my card shuffler I am planning to buil

I am trying to build (3d print mostly everything) a true random card shuffler. like the ones that are under the tables in the casino.The plan is like this (viewed from top, my wheel will be laying down instead of standing up like in the video)Everything will be controlled by an Arduino.It should consist of a big wheel with 52 slots of cards. cards will be fed one by one from the deck into the wheel. After all cards are fed. A random order will be generated with which the cards will be thrown out of the wheel on the other side one by one.throwing out the cards will be easy, there will be a servo with a specifically shaped plastic piece that will come up and down from beneath the wheel through its middle.feeding the cards into the wheel one by one is something Im not sure if I am planning correctly.Im thinking about two options of feeding as drawn.Option A: Cards are staying in a casing that on the left side there is a slit that should allow only one card to pass. A pusher wheel coated with rubber or foam should spin and push one card through the slit, the sensor is there to know when a card fully passed to the big wheel (entered the sensor and then exited the sensor). Then the pusher wheel stops and waits for the big wheel to bring the next empty spot.Option B: Because the card might not go all the way in to the big wheel, Im thinking maybe put another “feeder wheel” that will constantly spin much faster so the cards will actually be forcefully thrown to the big wheel. The “pusher wheel” will just feed one card slowly to the “feeder wheel” to be picked up by it.Sorry if this might be the wrong subreddit, but Im thinking there are imaginative and helpful people here that might help.What do you think about my two options? Do you have a different approach to feeding the cards? Do you have a totally different approach into all this thing?I am trying to keep this whole thing as simple as possible but also reliable as much as possible so that cards wont get stuck or two picked up at the same time, etc… Also want to be able to print most of the stuff.Thanks a lot. http://ift.tt/2atR3cX

D-Bot homing issue, X axis

I finally got my Ramps setup wired, and for some reason my X axis is super weird when homing. Here’s a video of what happens. In this video I am homing twice. The second homing sequence happens after a few seconds pause. Sometimes when I home, instead if stuttering back and forth the carriage move almost all the way over to the right. Sometimes it moves to the center. When I move in the X axis by clicking the arrow buttons it’s smooth. Only when it homes does it make the weird grinding sound.Edit: Resolved. I had the Y stop in the wrong position. http://ift.tt/2aW272T

Some months ago I made a post here asking if it was a good idea to build my own 3D printer using my high school’s resources. Now, with the help of /u/Talos3D, I have finally built one!

I made my first post here because I had intentions to get a 3D printer for my personal projects. I had access to my high school’s printer and thought it might be fun to use it to build my own. However, the printing turned out to be the easiest part./u/Talos3D offered to help me on my first post with my project through helping find parts and with his experience with printers. Throughout the project I have learned more about printers than I could have ever imagined. I have encountered endless problems and learned how to solve them, It has made me want to break down and cry, and It has been extremely rewarding just the same.For an album of all the images: http://ift.tt/2asrYhW started with the frame:http://ift.tt/2aFLXwS the frame parts came in at full length, I decided not to cut them and the printer ended up being a meter tall! http://ift.tt/2asrCba together /u/Talos3D’s carriages:http://ift.tt/2aFM1wR up the assemblyhttp://i.imgur.com/16ksyDL.jpgThe first print turned out horrible, but I can’t tell you how excited I was when it worked for the first time: http://ift.tt/2aFM0ZI shot of the internals:http://ift.tt/2assjkH went through a bit of a calibration hell every once and awhile:http://ift.tt/2aFMkrs finally started coming together as I replaced all the printed parts with higher quality ones from my own unfinished printer:http://ift.tt/2assxsa are some of my prints! (PLA)http://ift.tt/2aFLESN in the end, taking the hard route was well worth it. I learned tons, picked up a whole new hobby, and I now have my very own printer with accompanying bragging rights of having assembled it myself. I would recommend anyone thinking about building to go for it as It’s an awesome experience.And a huge thanks to /u/Talos3D who helped me build this; I couldn’t have done it without him. This printer was his own design. Please give him a shout to learn more about his printers.The original post: http://ift.tt/2asrOY1 for reading.
