Combinable colourful easter eggs. The parts twist together in multiple different ways to make colourful patterned eggs.

Inspired by Jakub Lattenberg's similar design

There are 5 parts, each with a thick and thin variation. Sorry about the weird numbering.

• Parts 2 & 3 are a core that the other parts twist into.
• Part 2 is a “Pine cone” style version of part 3, making it fit parts in 2 directions
• Parts 1 & 5 is a simple spiral outer which fits into parts 2 & 3
• Part 1 is a “Pine cone” style version of part 5, which fits parts 2 and 3, but when combined with part 2, the pine cone diamonds line up, leaving space for part 4
• Part 4 is an outer version of part 5, designed to fit into the gaps left by parts 1 + 2 combined

You can combine these parts in the ways above to create multiple patterns of diamonds and stripes.

Each egg has a thin stripe version and a thick stripe version. The thick stripe versions are indicated with a T in the filename. The thick and thin versions are not compatible. The thick versions are much stronger and have much larger tolerances. Only print the thin versions if you think your printer is up to the challenge.

In the images, they have been coloured as:

1: White
2: Light blue
3: Dark blue
4: Green
5: Yellow

All of the “Pine cone” style parts will need lots of supports and may be more fragile, with all other parts hopefully not needing any.

I made this model quite quickly, so I haven't had time yet to try printing any, but the tolerances should hopefully be large enough. If they aren't, tell me, I will try to make a larger tolerance version, or you can fiddle with your slicer settings.

Sorry about some of the weird gaps, I was quite rushed making it.

Please post a make of your prints! 😀

When I made this, I printed parts 1T, 2T, and 4T. These are the Pinecone style parts, so the other parts should work. Some sides of the part 4T failed because I didn't use enough infill, I am trying to improve the design to fix this, but for now it should be alright. Part 2T looks a bit strange because some of my tree supports failed, but that was a problem with me trying to adjust my retraction settings for PETG.
Aside from these (many) problems that were mostly my setting's fault, The thick stripe models fit together easily. I definitely don't trust my printer to try the thin stripe versions, only print them if you are absolutely sure it will work, since they are much more fragile, and have much tighter tolerances.

I first designed this for the Printables easter challenge, inspired by Jakub Lattenberg's similar design, then noticed the Thingiverse colour challenge, and thought about how I could create combinable "Pine cone" versions that could each be printed in different colours, to make colourful, interchangeable patterns. I created the spirals by intersecting twisted wedges with an egg shape, and the pine cone style is two stripes intersected through each other.
