Summary

Grow a tree with your 3D printer!

Build your own custom fruit tree. Change it within seconds to have it fit to your latest fruits. Pieces snap together and the tree is stable. The fruits are hold in spirals that bend down and wrap around the fruit.

It is customize able with different branches, trunk pieces, leaves and roots. Start small and let it grow higher.
Check out how it works in this animation: https://www.youtube.com/watch?v=pByeTKZoU_U

No support required and it also prints with small 120x120mm printer. You could also go crazy with colors with just a single extruder printer.

You can of course also use it to hold other things then just fruits.

[Update: Very slighlty increased the trunk connections tolerance. Because I tested it with a very high infill and it turned out that disconnecting is too hard with it. The updated version works now also fine with very high infill. If you like the lower tolerance version, they are in the Trunk-Pieces_Lower-Tolerance.zip now. If the new should be still a too low tolerance for printing with PLA let me know and make a extra version for that. I can't test PLA myself.]

Instructions

No support required, ABS with raft recommended. (Raft at least for the branches when using ABS) ABS lets the spirals bend better and pieces connect easier.

For a basic tree you need the following:
Trunk-Base.stl
Trunk-1xSlot.stl
Trunk-Crown.stl
Leave.stl x6
Crown-LeavesTop.stl
Branch-Normal.stl (or any other branch)
Root-Normal-Wavy.stl x6 (or any other root)

Branches spiral sizes are the following:
Branch-Big: apples and oranges
Branch-Normal: Pears, big nectarines and small apples
Branch-Small: Peaches and kiwis
Branch-VerySmall: Prunes and strawberries

Those fruits are just examples of sizes that fit best to give you an idea.

  • Not only the trunk length can be added on, the leaves as well. 9 leaves pieces connected in a loop build the magic bracelet of torment. There is a hidden case piece that can be put in the base piece. You can just hide stuff in there or use it to put more weight at the bottom which can be helpful when you are aiming very high. It also recommended to use at least the normal length roots for stability. If you wonder how high it can get: ca 3.5m with 1kg of filament which is much higher then most ceilings.

Hello.

Can i use PETG?

I would suggest a straight leaf so you can customize the shape and distance of the leaves

Hey! That's a great idea! I love it!

But how do we know the filament is food-safe? I mean, PLA alone might be, but then there's the color in the filament and the extruder etc. Who knows what will be left on the fruit?

I'm pretty sure pesticides remain the bigger problem. You have to wash your fruit or peel it anyway. ABS is also used for Lego and lots of other plastic things, if something should get on the fruit then as sprinkles of a not clean print. Just sand it to make sure. But if the smoke of the material is already not a problem it will be not something that is poisoning.

What print settings and nozzle size did you use?
I can't get the crown piece printed without the edges curling up.
I print in PLA.

I'm using ABS for all my prints. 0.2 mm layer height, it might have been something like 50% infill for that and normal speed. Do you mean it curls up off the board? In that case using a gluestick or hairspray helps to make it stick enough. I don't have any experience with PLA to speak off though.

No, it adheres fine to the bed, only the outside layers of the overhangs start to curl inward after some time, ruining the print.
What machine did you make it on? Did you use cooling?

I'm using a UP! Mini, settings are there also much simplified and it doesn't really print with PLA. It has a heating bead and a enclosure. When I get warping on a big print the only thing I can really try is to print fast or increase infill. ABS and PLA have also quite a lot of different properties.
Have you already printed the other trunk parts and some branches? Do they snap together well in PLA? I could quite easily distort the crown model to be more thick and with it has less overhangs if that helps but the transition would then not look that good. That could then be a alternative stl.

Yes, the other Parts snapped together tightly, but not too tight.
I finally made it and printed the crown.
It was a cooling issue. I printed it now with .8mm walls, 25% infill and heavy cooling from a new made fan nozzle.
Thanks for your offer, but the part can be left as it is. ;)
BTW: i use a k8200 Printer with e3d v6

Cool! Would love to see your finished tree..

This is way to big for my cramped counter top, but it would be great as a hanging vine...

No clue how to go about doing that though. lol

You gotta make room for fruits, lots of fruits! Hanging it would be too tricky.

I had an idea similarly for this challenge and this one just blows mine out of the water!

/r/3dprinting says that this should win all the contests!

Functional and so beautiful. Excellent work.

Wow!

Do you think PLA would work?

Theoretically yes. The main issue I see is that the spirals could bend significantly less. The pieces would then also snap off again harder when you want to customize it again.
Unfortunately I could not test it myself because my printer doesn't like PLA at all. If anyone here can let me know how it works with it that would be great.

Printed the legs, base and a few parts of the trunk so far. Not issues and it snaps together perfectly! I'm going to start printing the branches and I will report back. I'm using a printrbot simple metal by the way.

Maybe I'll give it a shot thanks !
