Second Thingiverse Post / Thing I made: Whirlpool Dishwasher Part WP8268846 (AP6012267)


I successfully modeled and printed a pair of replacement basket clips for my Mom's dishwasher.

Here is the thingiverse Link: http://www.thingiverse.com/thing:1720070

... and the completed parts:

Installation is pretty easy.

Squeeze this clip and slide the drawer-slide stop up.





With that off, the wheels slide right off the end.


The wheels snap on to the new 3d printed brackets, and the brackets snap on to the dishwasher basket.


Note: The brackets are in the wrong spots in this picture. 

The rear brackets go in the rearmost basket hole.  The front brackets go in  the fifth hole from the front.  If you put these in the wrong hole then the basket won't slide all the way out.

My family is laughing at me for buying a $200 3d printer to make two $20 parts.  Let them laugh, one day I will rule the world.  :D

First Thingiverse Post / Thing I made: Tiny Screwdriver handle

I published my first thing on Thingiverse:

http://www.thingiverse.com/thing:1717111

It's a small "thumbdriver" handle for 1/4" hex bits.


I am enjoying my new printer very much.

I made a thing... Poorly: Replacement Contigo Water Bottle Button

Just before bedtime my daughter brought me her water bottle and asked if I could fix it.



The button and stem, on the right, are what release the valve so water can flow.  It's from a $7 Contigo water bottle, so no big deal.  I offered to go get another with her before school tomorrow, but the she said the magic words.  "Can you make a new one on the 3D printer?"

Yes Daughter, yes I can.

So I modeled it in Fusion 360:



Then printed it out and viola! One functional, if not very attractive, replacement water-bottle button.

I made a thing: Random Dishwasher Parts

Mom asked me if I could fix her dishwasher.  The top rack keeps falling down.

Digging in, I found the problem.  This is the upper dishrack clip/axle.

It's broken, obviously.  The little clips that are supposed to hold the wheels on are half gone.

Pricing it online, these clips are $25.00 each.  Ouch.  She needs four of them.  Cough & Sputter.

So I did what any self-respecting cheapskate would do.


No, not duct tape..  :)  I made new ones.

Here is the 3D model in Fusion 360.




And now my printer is humming away, making a new one.

I'll test fit it this weekend.  If it works/fits, I'll post the model, and the Dishwasher model/part number information so the universe can share in my delight of not paying giant piles of money to buy these.

Fixed: Random intermittent "External E-Stop Detected" in Mach3

The Marietta Makerstation has a 3 axis CNC wood router.  I tried to use it last night, but hit a problem.  The Mach3 software would stop every couple of minutes with an error "External E-Stop Detected."

That was frustrating.

I found a fix for it.  Under the Config >> General Settings menu there is a "Debounce" option in the upper right corner of the screen.  I entered "125" here and this solves the problem.

Explanation:  The router has a lot of electrical noise.  "A lot" is an understatement.  When you turn it on, our doorbell rings.  Occasionally this noise will cause the pc to detect a blip on the E-Stop input pin.  The debounce setting tells the system to ignore e-stop input unless the signal is present for 125 * 40 microseconds, or 5 milliseconds.

Magic.

Here's the first part I've cut on that CNC machine.  It's a backboard for the Wally 3d printer I'm making.

Book I read: 61 hours (Jack Reacher) by Lee Child

I read another Jack Reacher book, 61 Hours.

These books are my guilty pleasures.  I partcularly liked Mr. Reacher's humanity in this one.  He wasn't, and isn't, a superhero.

How does one learn to convert fear into aggression and action?

I would like to know.

Congrats, India! Launch of PSLV-C33/IRNSS-1G

It's not getting a lot of press here in the US, but India has a pretty awesome space program.  They just finished orbiting their 7th navigation satellite.  This gives them a completely home-grown alternative to GPS.

Here's the launch of  PSLV-C33/IRNSS-1G.


I'm curious about these sheets that appear to fly off just after liftoff.



My country learned a very painful lesson about the cost of falling ice and foam during launch.
