Happy Easter!

Are you tired of traditional Easter egg hunts with real eggs you have to try not to break while you color them? Or maybe you're tired of worrying about what the one or two eggs you didn't find will smell like in a few weeks?

3D printing to the rescue! This year impress your friends and family with this cutting edge Easter technology! Yes, this limited edition, Easter Bunny approved, 2016 3D printed Easter egg has not 1, not 2 but 4! YES 4, moving parts!

But wait, that's not all! Act now and not only do you get the 4 spinning parts, but you also get the 2 integrated legs that snap out of the case to easily turn this cutting edge egg into a beautiful centerpiece fit for any occasion!

Quick, act now!!! Easter is this Sunday, Sunday, Sunday!!!

Ok, had to do the fun sales pitch. Hope you all got at least a chuckle or two out of that.

Here's the official story for the design inspiration:

The design for this spinning Easter egg gimbal was inspired somewhat by this thing: http://www.thingiverse.com/thing:1228453

I made a handful of these 2016 gimbals for our new year’s party and people really like them. It was the first movable print in place object I made. The concept of a single print piece with moving parts was pretty interesting, so I started to experiment more with print in place objects of my own design. My first design was round like normal. My second design used circles and squares. From there I was thinking of a way to get out of the round and symmetrical designs. With Easter approaching an egg made sense. And, if you own a 3D printer, you inevitably end up with remnants from a roll of filament and sample filaments in all kinds of colors. So, here’s a fun, festive way to use up some of the filament remnants or samples you have laying around!

The part of the story I left out:

Somehow I ended up with a bright pink PLA sample from Color-Fa-bb… It prints great, but it’s bright pink. There not many things I can think of that need (or want) to be printed in bright pink. Hmmm… What to do, what to do…

Ah ha! Easter! Pink goes well with Easter!

Must. Design. Something. For. Easter.

Print Settings

Printer:

F F C P

Rafts:

Doesn't Matter

Supports:

No

Resolution:

.2mm

Infill:

15%

Notes:

Extruder temp:

PLA, about 195 C, Wood filaments, about 200 C, ABS (white), about 225 C

*XT copolyester (blue) 245 C

Bed temp and prep: PLA 45 C, XT copolyester 70 C, ABS 90 C. All printed on a clean PEI sheet

Cooling: First layer, no cooling for all materials. Following layers , full cooling for PLA, no cooling for ABS or XT.

Speed: 50 mm/s worked well.

Note: ABS and XT shrink some. I recommend scaling the models 101%-103% If you plan to mix ABS and PLA.

Note 2: My RH hotend is all metal. Printing above 230C with a PTFE lined hotend isn’t usually recommended.

How I Designed This

I ended up making five different iterations before being satisfied with the results.

1. Proof of concept. Also included an offset piece and a non-symmetrical piece. Passed proof of concept, offset parts didn’t spin well.
2. Added grass and legs to the case, made things symmetrical so they would spin better.
3. Revised the legs to snap in place better, beefed up some of the pins on the middle, added text.
4. Revised the Happy Easter text to print cleaner, minor fine tuning of the pins and sockets.
5. Rounded the tips of the grass blades to make them less likely to warp, small revision to the text.

Attached here are the rev 5 files. I’ve also started playing with some dual extrusion prints of this, so far so good!
