Marathon Etsy-ing

Phew. Did some catch up on my Etsy site and got a bunch more products listed this week including:

>Marathon Etsying

  • Bird Christmas Ornaments and Wreaths – for the Nature Lovers on your Christmas list!
  • The National Museum of the Marine Corp – a special model for a show I did in Quantico, Virginia. The model glows in the dark and can be lit within by LED
  • Library of Congress Ornament– which scored me a trip to the White House.
  • Schrodinger’s Cat and Box – It has been a surprise sleeper at the craft shows, so I decided it was Etsy-worthy. :)
  • Breastfeeding Pendants – where my 3D Printing journey began!
  • Heart Helix Pendants – My current favorite necklace– hearts twisted into a double helix.

Enjoy!

Fun Print – Le FabShop’s Wolverine Claws

The le FabShop’s Wolverine Claws were making the rounds on the Internet and they looked amazing, but I did not feel compelled to print them. My husband saw them and instantly wanted some… but still I hadn’t quite worked it into my 3D Printing schedule. And then…. The 3D Printed Nerd nonchalantly mentioned in a VLOG that he printed them.

Suddenly I was swayed. And I already have grey filament in my printer from the Fun Police Sheriff’s Badge. It was destiny. So I went ahead and gave it a whirl. This was before The 3D Printing Nerd’s full video on the claws, so I was still blissfully unaware it took 3 tries to get them right. That might have deterred me, but luckily I didn’t see the video yet and luckier, my first print was a huge success.

I printed at 0.25mm layers with 10% infill. The Thingiverse instructions recommend rafts. I forgot to turn rafts on in Simplify3D, BUT knowing the brutal overhang was coming, I did glue stick the absolute heck out of my bed. That was sufficient to keep the claws stuck on the bed. I did have a minor first layer issue, so the very first layer of one of the claws was fused together in my print. I freed that up with Exacto Knife and SHEBAM. We were in business.

Sadly, my husband STILL doesn’t have the wolverine claws he desires. My four year old took one look at those things and yeah, now they are his. : )

It is such an amazing and impressive design. Many thanks to le FabShop for sharing their design!

Print Diary – Fun Police Sheriff’s Badge

A friend of my brother’s passed away last week. He was in his thirties, so it was an unexpected death. Last night, my sister-in-law texted to see how soon I could 3D Print something for the funeral. She wanted a Sheriff’s Badge with one request– that it simply read “Fun Police”.

Thanks to Thingiverse, OpenSCAD, and Simplify3D, I was able to turn around her request fast.

Thingiverse and OpenSCAD
Thingiverse had a lot of Sheriff Badges to choose from. I went with the design by Bichiatari. I liked the standard six star approach and bonus– it was in OpenSCAD, which I taught a class on last June! I used his base code to make some slight alterations:

  • I made the points of the stars spheres to give it a more three dimensional look.
  • I changed the font to “Rockwell Extra Bold”. I liked the look of the text and I liked how thick the letters were
  • And finally, I changed “Sheriff” to “Fun Police”.

Simplify3D
Now, when I was done, the points of my stars did extend below the base of the star thanks to the spheres.

Fun Police - Test Run - Untruncated Spheres
I didn’t want to print those sphere bottoms

For my first trial run, I didn’t go to the trouble of making that flat in OpenSCAD. I just flattened the bottom when I sliced in Simplify3D. I simply changed the Z offset, so the bottom part of those spheres were below my build plate, so those parts wouldn’t print. A nice handy trick.

I also felt the proportions were a little off, so I scaled just the height of the object down so it was only 6mm high.

Rev 2
The first print was okay— and I bet they would have been satisfied with it. I didn’t like how the “E” at the end of “POLICE” printed out and I thought it would be a better use of real estate to make the letters bigger.

3D Printing - Fun Police - First Print
The First Print Had a Messed Up E

So I went back into OpenSCAD and made some changes:

  • I put “FUN” on one line of text and “POLICE” on another
  • I made the text bigger.
  • I resized my object down to 4mm high
  • Finally, I went ahead and chopped off the bottom of those spheres so it would all lay flat

For those interested in the code, the full OpenSCAD code is below.

As far as the second print— I liked it much better. I used the MakerGear Silver PLA filament.

OpenSCAD Code

//I thought the current height was too chunky,
//so scale it down to 4mm high after everything
//else is done
resize([0,0,4])
difference () {

//Rotate the star 30 Degrees, so it is easier to visualize
//and place the text
rotate([0,0,30])
union () {
    //The first two cylinders are our star
    //3 sided cylinder is a triangle
    cylinder(r=40, h=5,$fn=3);
    rotate([0,0,180])
    cylinder(r=40, h=5,$fn=3);
    translate([37,0,2])

    //Spheres at each star's point
    sphere(r=5, $fn=32);
    translate([-37,0,2])
    sphere(r=5, $fn=32);
    translate([-19,33,2])
    sphere(r=5, $fn=32);
    translate([19,33,2])
    sphere(r=5, $fn=32);
    translate([-19,-33,2])
    sphere(r=5, $fn=32);
    translate([19,-33,2])
    sphere(r=5, $fn=32);
}

//These cubes are our engraved lines
translate([-23,10,1])
cube ([50,1,4]);
translate([-23,-10,1])
cube ([50,1,4]);

//This is our text for engraving
scale([0.7,0.7,1])
translate([-30,3,1])
linear_extrude([0,0,5])
text("    FUN ", font="Rockwell Extra Bold");

scale([0.7,0.7,1])
translate([-30,-9,1])
linear_extrude([0,0,5])
text("POLICE", font="Rockwell Extra Bold");

//Finally this cube is to cut everything off at the bottom to make it flat
translate([-50,-50,-5])
cube([100,100,5]);
