Summary

Protect your precious hazelnut chocolate goodness from other hungry fingers with this lockable lid!

Can fit any lock with 5mm or less diameter shackle bar with 15mm straight.

EDIT #4: Small error found in original stl files that made the inside circumference of the lid little smaller. This may have been the case for those who reported this cap to be too small. (new 'Orig fixed' files added)
EDIT #3: Custom Larger size added (85X77x20) +1 for filament expansion
EDIT #2: Family size cap added (750g)
EDIT: 100likes! wow! For that, I uploaded a special version for you all! :)

Instructions

Print all parts.

Attach hinge pin with method of your choosing (I chose asetone sludge but friction welding / melting works too)

Put a lock on it :)

Oh my this gives me ideas. I need to make something like this for mason jars so my husband will stop eating all my son's M&Ms.

I need this so much

Aww you meanie! Are there any beer locking tops I wonder ;-)

Yes there is

I would love to see a customization version of this. I have many different types of jars I would like to use this on to keep roommates and coworkers from helping themselves to. Someone keeps eating my pickled garlic that I get shipped from Japan.

Hehe tough life you have... and that would piss me off too :)
But I agree, a fully parametric and open version of this would be nice and easy. I however don't have any experience with openscad (http://www.openscad.org/) that can do the job.
If someone has skills needed, they are free to convert / design this caplock for that software. After which that design would accommodate all kinds of jars and lids easily.. just input needed dimension and print..

Hi,

Thank you, I printed it.

Unfortunately 750g version doesn't work for 750g N... Jar in France... It is big enough to enclose the cap, but not enough for the glass...

Hi,

Sorry to hear that it didn't fit.. :(
I'm now starting to wonder how my diffirent sized jars are there :) If you'll measure and send me the dimensions of the neck width, lid hight and width, I'll modify it to fit your jar.. :)
(I'll add 1-2mm for filament expansion)

Hi FIdo,

The lid diameter is 84.6 mm, height 20 mm.

The neck width is 77 mm.

Thank you !

Custom version with 85x77x20 +1 for filament expansion added. I hope this fits :)

... And it fits pefectly!

I printed it with a layer height of 0.190 to save time, but the result is smoother than with 0.90, particularly on tilted faces.

I'm glad to hear that :)
& I hope your Nutella now stays put :)

I'll print this tonight. Thank you!

Hi guys, I have design a cap to secure the pin in. The link is below:

Pin cap for Nutella cap lock

Very nice.. Getting your Nutella stolen is no joke..! It happened at my former workplace, if only we would had been able to secure it, a lot of agony and suffering would have been spared.

Oh wow. With 3 highly dexterous chocolate craving toddlers at home this might just work where top shelf storage has failed!

doesnt fit my 750g family sized jar....
its too small...how big is ur jar??
major sad face!!! needs to be just a couple % larger!

Hi,
I'm sorry to hear that.. I knew while designing this that there are different sized jars and I picked the one that was available. But if you'll post the cap measurements in mm (diameter of the cap, it's height), I'll upload a family sized version here too.. :)

Hey THANKS HEAPS, the height is correct, the diameter is 84mm.

Its the Australian 750g family sized jar (if u want u use that as a file name go ahead!)

cheers
soti

No problem. I hope it fits now :)

Thanks mate, will print it and let you know how it goes!

ummm, so printing this, missus goes through nutella like you wouldnt believe!

Best thing ever!
