Another Cryptex (I first made out of wood before I was in possession of a printer). Special feature: you can change the code! (and better not forget it!)

I was searching for a tool to boost my pupils' motivation to do their math - and so, on every session
I "coded" the result of a bunch of exercises in the cryptex and hid some "reward" on the inside.

In the photos you see one of the prints - in the current version you have a diameter of 4cm and a length of 6 cm in the inside.

*Edit: Just found out that the idea is already out here :(

Simple Black








it depends...


Gears and numberwheels don't need any infill nor supports or rafts (at least I didn't, printing with PLA).

For the frame you want to have an infill of about 10% and for the part with the teeth you should consider supports to print the teeth right.

I printed it at 40000% size, which is about 3cm in diameter. That might not be big enough.
Can't you please indicate in the directions how many of each piece to print? You need 3 gears AND 3 number wheels.
Once I figured out how to assemble it (not very obvious) I managed to get it together, and it was nearly impossible to get apart. There is nothing to hang on to in order to pull it apart. For the same reason it is hard to turn the number wheels.
If you are going to give this to kids, I think you need to print it bigger, and even with the combination it will be hard to take apart.

It opens fine in Cura, had to scale it about 7,000 percent for it be good size in Simplify 3D. No worries...easy fix. Quick question...once built and you solve the code...to open it up...what keeps number wheels from sliding off too?

Basically...nothing :) however I made the experience that the number wheels sit thight enough on the gears not to fall off.

yeah... I was?am extremely eager to give this print a try but it errors out in all the different related programs, for printing. Any ideas on what I can do to correct the issue?

What program are you using for printing? [ I use Cura and had no problems loading the parts ] what program do you use for printing? I will try to see what happens in the program you use when loading the parts. [sorry for coming back to you with such a delay]

I haven't thrown it in any software other than makerware, flash force creator pro software, and sketch up.

And no apologies need. You don't owe us a thing!!! But it's awesome that you would take the time to respond and help!! Thank you.

Hey there! I just downloaded Makerware (that is MakerBot - the only download I could find) and it seems to me that MakerBot just scales them to a 1/1000 of the size I've given the thing while designing it.

So as a quick fix, after adding the file to Makerbot, click on "keep size" in the first step. Then click the resize-button on the left and enter 10000% scale. You should already see the object (still very small). Then enter 1000% and you should have the "original" size.

As you tried it with many other programs, I assume it's a blender issue and that only Cura is the exception to the rule..pity!

Good luck and thanks for the comment :)

scaling on the objects is way off
