Threaded and tight cream jar

Use case a cream jar for hand cream

I have printed a whole bunch of these cute little threaded containers (Also because they are a great benchmark to check if your printer has a clean and even extrusion, which is apparently not always the case for the Prusa Mini, but that is another story). In my tests they were water tight without a seal ring. I would not completely count on that, but they are clearly tight enough for hand cream.

The credit for the idea goes to my girlfriend, who spread the contend of one purchased pot of hand cream over numerous little containers around the house. This avoids the big pot getting old and you have hand cream immediately available when your hands start to become dry, which is always a problem around here in winter times. 

I have one of these little containers on my home office desk for many weeks now and it has proven to do the job well. It does not show any signs of leakage and the cream stays nice and fresh.

Can I store other small items in these containers?

Well, that is a tricky question. I propose you give your intended use case a very thorough consideration first, followed by a well supervised extensive testing period and in addition do a peer review with someone you really trust… Or you simply man up, take a decision and live with it ;-) After all, it's your printout and your life!

Printing

Printing these containers and lids is very simple. No supports and no brim is needed. Simply print both parts in the uploaded orientation. You can choose the infill basically freely, it is not critical at all. I typically used 15 or 20%, but even 100% infill will not use noticeably more material or printing time.

You can use basically any material and any printer should be able to do the job. I have tested it on a Prusa i3 MK3S, on a Pursa Mini and on a Ender3Pro. I have also mixed PLA and PETG containers and lids and everything still fits nicely.

Scaling 

I have not tried to scale the parts before printing, but as I have used only easy-to-print 45° angles in the threads, I would assume you could scale the parts up as much as you want. I am not sure if it makes sense to scale them down further.

That made me really sad. If you want to seriously remix this design, please contact me and I will gladly approve that.
