3D Printing – The Easter Egg

Yesterday, I designed an Easter Egg using Tinkercad.  Today, I printed the Easter Egg.  Creating the Egg in Tinkercad is easy.  They have a egg object.  Hollowing out the egg is easy; copy egg, reduce the size, make it a hole, align the solid egg with the hole egg, and group.

Making the two egg halves with the crack was more complicated than making the chick.  The chick is two circles for the body, two circles for the eyes, two flatten and stretched trapezoid for the wings, the heart shape for the head, and Tinkercad’s  chicken foot object for the feet.

To see how I created the crack in the egg, check it out here.  Note:  I am working on other cool chicks, so the design my change.

I probably could have made the chicken bigger, maybe I will.

The egg was printed on Ultimaker 2+ printer.  I read that beta version of the Cura Software allows more control over supports.  Yay!

Amazon Echo Show Privacy Shield

I do not believe that Amazon is spying on us, but there are a numerous hackers in the world.  And, getting dressed in front of a camera….

This privacy shield is for the Amazon Echo Show to cover the camera.  It will put the device to sleep because it can not detect movement in the room.   You can still access the three buttons on top of the device with the shield installed.

The Camera is in the top center of the device.

I put “Alexa” on the shield because that is the wake up word for the AI.

Clackers

It all started on Facebook and someone saying “Do you remember…”  Yes, I do remember Clackers, they were fun to play with, but dangerous (will at least in today’s world.)  We would get hit with one or both of the glass balls and go ouch or whoops.  However, in today’s world, they are safer than the Tide Pod challenge.

My 3D printer and I were not getting along, so we both took a break from each other.  After the Facebook posting, I decided it was time to put the print back to work.  And, one of the simplest thinks to design and print would be a ball with at hole in the middle.

I used Tinkercad to design it.  5cm ball with a hole in the middle.  I then did the thing I been regretting for a while, I cleaned, oiled and balanced the printer.  The first print failed, the item was not adhering to build plate.  Failure.  I rebalanced the build plate.  Failure.  I removed the build plate and cleaned it with soap and warm water and rebalanced the build plate.  Success, I had one ball for my clackers, so I printed a second one.

The string is only nylon string with a loop tied at the top and a knot at the end of each ball.

My family have official declared me weird.

 

Stand For Fluid Painting

Fluid Painting can be messy.  You pour paint over the canvas and it drips over the edges.  What a mess!  I am not a clean freak, just a person working in limited space and I need my table to draw and do other things.  So far, I have limited myself to 4″ canvases, and I have a 3D printer sitting right next to my work table… I decided I would design and print a stand for my pour paintings.

The maximum print size of my Ultimaker 3d printer is around 8 inches, width and length.  The height can go up to around 12 inches.  So, this project was perfect.

The catch basin is 5″ square, or in my design world 127mm, and 1″ (25.4mm) high.  Just in case different colors dropped from the different edges of the canvas, I divided off the catch basin and add drain notches.  It didn’t need it, but I placed pegs to hold the stand, and divided off this compartment to keep paint off of the stand.  It took around 11 hours to print.

The design was done in Tinkercad and export as a STL file.  The file was imported into Cura and where a .gcode file was made.  I used the “normal” setting because the “fine” setting indicated it would take 23 hours to print.  Therefore, some warping occurred because of the setting and because I select not to add a Brim support.

The stand was also designed in Tinkercad.  It is 3 inches high.  The break in the structure allows for air to flow under the canvas.  It took around 4 hours to print.

The notches on top of the stand, allows me to put some other type of support under the canvas to lift off, in case I want to reuse the stand before drying is complete.

The finished product.

The colors, yes I used Color Shift paint by Folk Art and grab the black and 4 other colors.

The test.

Ok, some of the holes leaked.  The center dividers should have been larger and I did not pour out of the basin as I expected.  I do not know if I am going to tweak the design and reprint it or not.  Probably.

I did get a cup (one ounce) out of the basin.  It should go nicely with another pour.

Chocolate Explosion

I am calling today’s Fluid Painting Chocolate Explosion.  It reminds me of chocolate milk.  This painting took on a different twist.  First I designed and printed the 3D object, shown below, to create my painting.  The object has an 2″ diameter, and 1″ tall.  The holes are 8mm with the center hole 10mm.  By applying a thin layer of paint to the canvas, I was able to place the object on top of the canvas and fill with layers of paint.  No paint leaked out until I lifted the object.

The small painting measuring 4″x4″.   First I put a light pink color on the canvas, and then place the object on top.  I then pours light blue, dark blue, light yellow, chocolate, and pink into the container.  I let it sit for a few minutes and blew gentle on it to release air bubbles.   When I lifted the object straight up, the paint flowed out of the object quickly.  After tilting the canvas, this was the result.

3D Printed Tree

I know Christmas is over and the new year has started, but this was my main adventure for November and December.

Many months ago, I got the idea that this year’s Christmas card would be 3D printed.  After many rough drafts, I decided on the “We Wish You a Merry Christmas” design.

dscn2819

The initial design phase went smoothly.  And then, I had more ideas.  The words on the tree should turn, so the tree would look like it had stagger branches.  The words on the tree should be readable from any angle.  Oh, it need a tree skirt and the simplest design would have stars on the skirt.

It then occurred to me the tree needed a train going around it.  Well, the train could not literally go around it, because the size of the train.  My printer would not be able to print the tiny detail the train would need to allow it’s wheels to turn.

I still was not entirely happy with the tree skirt.  The tree needed presents.  I designed three unique presents and place them under the tree scaling them to different sizes and placing them under the tree at different angles.

Designing the tree was the easy part.  Printing the tree out, proved to be the most challenging part.  The filament started grinding.  I regularly had be dismantle the extruder box to remove filament.  I also had to dismantle and reassemble the printer head on no  least three occasions to correct issues.  That is why only 6 of these Christmas tree were sent to friends and family.

There were eight .stl files created to print the tree.

Dominoes

My father-in-law has shown very interested in the 3D printing.  Asking questions about how it works and what can it print.  Before Father’s Day, I sat down in from of the computer and said “What can I print for my father-in-law?  He plays dominoes every Friday!  I can do that!”

I looked up the dimensions for Dominoes; design the dominoes; and created the case to look like a domino.

His own personalized dominoes.  I also printed a set for my dad for Father’s Day with his last name on them.

3D Print – Passenger Car

This is the Passenger Car in my Train Series.

DSCN7371

The wheel assemble was printed with the side shown on printer plate, which provided for the smooth finish.  I designed little lanterns and put them by the door on both ends of the car.

DSCN7377

I designed the seating without the arm rails because I believed it may have been too delicate to provide a good result.

DSCN7383

The train is now longer then the white cutter where I took the previous pictures. Soon, it will be too long for the shelf it is sitting on.  But, the wheels are spinning and the locking devices are functioning.

DSCN7387

Object Size (W, D, H): 27.75, 146.43, 56 mm

I made the Passenger Car slightly longer than the Caboose.  The extra width was due to the roof over hang.
