Now Playing Tracks

million-dollar-king asked:

If you have an electronic recycler in your area go ask for the glass out of old scanners. I've ripped about 6 8x8 sheets so far for mine and other's printers. :)

I’ve got an old scanner in the garage for just this purpose.  I’ve thought about going to a recycler but for the time, money and effort involved I usually go to the craft store and buy a picture frame.  Somehow it’s cheaper to buy a whole frame with glass than to go buy a piece of glass.  A single frame + glass cutter gets you a lot of pieces to work with.

Which printer did you first build?

I first built a MakerGear Prusa Mendel.  It took my 6 weeks.  I had never built anything at all before that.  Not even glue together models.

And now for something completely different - a 3d printed completely smooth temperature based color changing dildo.  They also use an ABS vapor bath to smooth the finished model.  I’m going to get an old fish tank or something to try a vapor bath of my own.  I don’t want to be cooking acetone in my good cookware.

This is a nice electronics enclosure for Raspberry Pi.  I had to modify it a bit because it turns out the video out on my board is skewed at an angle so the normal model wouldn’t close right.  

I ordered about 10lbs of different colors of plastic and I’ve been going crazy building stuff lately.  Electronics enclosures for my arduino projects are a big thing.  

I’ve also got a few dozen servos on order and I’m going to try to make some hexapod or multileg walkers and/or quadcopter.  Not sure yet.

Just started experimenting with communicating with an Arduino via R/C transmitter.  It’s working really cool so far.  Can’t wait until I can start driving some motors remotely.  

3D Printed Quad Copter Arms coming right up.

The first four I figured out a good fit for the motor.  Then I started to grow the shape out by adding a covered arm.  The first few designs were too flexible / weak so I added more supports until eventully I have part number 8 that has a nice tight push fit, holes for set screws to hold the motor on both sides, hollow tube arm wtih vertical supports for strong z-axis.

The next step is to add figure out how to connect the arms to the base, and figure out how big the speed controllers are.

Next project - learn design

After many months and two 3d printers I can comfortably say I am very good at printing 3d objects, but I totally suck at DESIGNING said objects. I’m a programmer by trade, so my tool of choice is OpenSCAD. I can kick out shapes and objects pretty easily, but as my ideas become more complicated and require multiple pieces I find it a very poor tool for me mentally. Single shapes are easy for me, but the whole multi-part vehicle designs are very difficult. I can see where blender or some other cad program would be much easier to work with now.

I’m taking apart some roombas and computers and looking very carefully at how they are put together. How they are strutured so that they CAN be put together, as well as taken apart. Learning about what kind of tolerances are required for snap fit parts, water tight and living hinges. Starting with simple machines and then I wil branch out from there.

Rebuilding the Prusa…

After a good run I think the Prusa is getting a tear down. The triangle frame concept is nice, but I’m going to try some aluminum t-slot stuff and see how that works. Keeping it calibrated with all the driving it around demoing I do is getting too much time to maintain.

Have 3D printer, will travel.

Lately I really prefer the smaller footprint MakerGear Mosaic to the Prusa Mendel.  It’s nice to be able to put the whole thing in a box and move it around for demos.  It’s on my desk at work right now and working great while I code away beside it.
