Summary

Instructions on how to assemble are in the YouTube link below:

UPDATE 3.0: I've decided to release the object files in .ipt form(Autodesk inventor format) so that you can you can tweak tolerances and improve designs by yourself. If you don't have Inventor, download a trial version and tweak it that way. Thanks for downloading my design!!!

UPDATE 2.0: There was a design problem that I didn't find until now (thank you Runkel!). SB should now allow the safe door to close flush. Sorry for not sorting this problem out sooner!

UPDATE 1.0: The safe Is now FINISHED! You should download ONE 1-KP file and then download the rest. The 1-KC files are now numbered as "1-KP-xx", the "xx" refers to it's specific key code (eg. You want your last combination number to be "5", so you will download "1-KC-5").

This combination safe has four combinations that are fully customizable to the user. The pictures and the STL files will look different as I have tweaked and improved the design since building the safe. I created this to stop my cat from peaking and stealing my money. Yes you read that right, my CAT!

You will need:
four M3.5(you may need to saw the length down to size)
Glue (most parts shouldn't require this)
Hammer(again, most parts shouldn't require this)
Pliers(explained below)

Tips:
The O-ring clips are a little hard to pry open by hand, but easily doable. They should click into place once fitted and can be taken off just as quickly.

The Notches on the code wheel(IKP and IKPR) may need to be sandwiched together with pliers, they're a tight fit and should not fall out once pressed.

Please Comment about any problems with assembling the safe or files.

Notes:

PLEASE READ!!!!

The model was designed with the consideration of tolerances, IT MAY FIT LOOSE WHEN YOU MAKE IT!

Please use glue if possible, but please comment if there's any problems!

My printer uses a 0.5mm extruder with a 0.3mm layer resolution. This causes my prints to be a little wider than designed, and hence why I made holes and connections wider.

What is the size of the largest part

Hi, this looks like a great design and I would really like to print this for my nephew, but the instructions are not very clear, how would you choose the combination?

j'ai fabriquer le coffre mais le soucis je n'arrive pas pas a savoir comment faire mon code en plaçant les petit truc sur chaque roue ,j'ai imprime le 11 pour la fin mais je voudrais avoir le code 2 1 3 11 comment placer les curseur merci de votre réponse

The only issue I'm having is trying to figure out how to set the combination for the first three numbers. I'm going to experiment to see if I can't figure it out, but it'd be great if we could get instructions on setting your own combination.

bonjour popurrait tu me dire si tu as reussi a faire ton code et si oui merci de m'expliquer cordialement

No, I did not figure it out. It's rather non-intuitive, as each number is relative to the next number. As I had a deadline to get the safe working by (it was part of a present for my wife for Christmas) I just played with it until I got decent (but not what I wanted) numbers.

Here's what I did discover: it appears as though the number of turns are:

  1. 4+ turns clockwise
  2. 3 turns counter clockwise
  3. 2 turns clockwise
  4. 1 turn counter clockwise

Pffffft! Instructions?! I'm just going to stick parts where they fit!

what parts do i print there are a ton of files

how can i set the opening code to a code from my wish?
the last digit is clear, but how the first 3?

こんにちは、メーカーウェアのソフトでモデルを回せないんですか?
Youtubeには色んな回す方法のビデオがあります。日本語が変ですいません。

Can you turn all of the models lay flat on the platform for me?

WoW!!! really nice. I would like to make one, this is fairly large though and my slicer says 6hrs 53 min just for the box alone. I am not sure it would all work if scaled to 50%. I think there may be some tolerance issues. Any chance you can post the source files?

Again thanks Nice work!

6 hrs 53 min is NO time compared to what I have printed. I plan to scale mine to to 200%. also, what speed are you printing at?
you seem to be printing quite fast.

Hi n9jcv,

Thanks for the comment!

I'm quite busy at the moment with student stuff but should be ok with uploading source files for you to manipulate.

I haven't tried printing the design at 50% scale so I have no idea how it will turn out. I used Autodesk Inventor to design it so if you tell me what type of CAD file you want me to export, I will upload them onto here.

Files for Sketchup please if you can do that. If not, then just the Inventor files and I will have to learn Inventor with a free trial. Thanks

The stl plugin for sketchup adds direct stl import into the program. I use it all the time for remixes. File > import, change the file type pull down to stl and away you go.

Hi, Sorry but have no way of converting the files into Sketchup formats.
I have uploaded them in Inventor files so your going to have to use a free trial of inventor(I've used Sketchup before and the transition to inventor was pretty easy so you should have no problem!).
