Wallet Via 3D Printing




About: An engineer with 25 years experience across aerospace, medical ophthalmic, power tool, and industrial product categories. Now a passionate entrepreneur creating unique solutions that excite our daily lives

Print your own Veos wallet and enjoy a great front pocket wallet experience.  The 3D printed frame holds cards that slide out the side for use.  Then, put a picture of a loved one behind the frosted window to enjoy, or an I.D. that makes for quick I.D. checks at the store.  There are even two different sizes available.  A λεπτός wαllet that is .22" thin and holds up to 4 to 5 cards.  And, a τακτiκός wαllet that is .38" thin that holds up to 7 to 8 cards.  The rubber band holds cash and receipts on the back, as well as holding as few as 1 or 2 cards securely in place on both models.

This project is for those Makers that have access to a Printrbot, or other printer capable of utilizing .stl files.  No need to struggle through CAD creation.  I am posting completed and repaired .stl files.  So the beginning of this project is to set your printer and have fun!

For those of you that want more enjoyment with less effort, I will post these 3D printed wallets for sale on Etsy.  Look for them in June.  Also, there are fully CNC machined aluminum versions with various plated finishes available.  Check out http://www.veosllc.com

Let's get started here!

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials Needed

F I R S T    T O O L S :
1.  Any 3Dprinter capable of utilizing .stl files.  Print size required is about 2.5" x 4.5" x .5" thick.
2.  Long nose, or wire cutting pliers.
3.  Small flat blade screwdriver
4.  Scissors

N E X T    W α L L E T :
1.  3/8" x 3.5" rubber band.  (This is a standard size available at any office store.
2.  (Optional, 1/4" x 3.5" rubber band if you prefer.)
3.  Fold back paper clip, with about 1 1/4" long body.
4.  A report folder with a frosted front cover.  The thicker the front, the better.  (Note: Report cover not shown.)

Step 2: .stl File Preparation

I created these models in Solidworks, then exported them as .stl files.  The next step was to utilize Netfab to import, repair and re-export the .stl files.  At this point it is time to load the files into Slic3R.  I used PLA to create my wαllets.  I used 2 solid layers before and after infill layers.  I also used 2 perimeters, and 25% infill.  The final product is both flexible and very robust.  Since different printers and materials require unique settings, I won't bother anyone with the rest of the detailed printer settings I used.

Choose which wαllet you prefer.  Check out the front page for descriptions of the models and differences.  Then download the selected file.  Load the downloaded file into Slic3R and select the printing options you prefer.  Once the file is processed and exported from Slic3R as a .gcode file you are ready to go.  Load this into your printer and print!

SIDE NOTE: the file is prepared so the front face is down on the printer.  You can view the Netfab screen shot and see the orientation of the axis icon relative to the part.  Two reasons for this.  One, I print and smush the bottom layer just a little, it yields a glass like smooth front face.  Two, this part orientation eliminates major overhangs.  

Step 3: Fabricate Other Parts

Time to cut the report folder up.  Cut a section from the front clear report cover.  The best report cover to use will have a thick front, one side smooth and one side frosted.  The one side smooth provides a nice clear view of what is behind it in the wαllet.

Lay the cut section over a credit card.  Use the credit card as a template and cut around the credit card.  And you are done here.

(NOTE: you can also use a milk carton if needed.  It just seemed a little gross to me, and the milk carton is not quite as clear once a picture is laid next to it.)

Next, pick up the fold back paper clip and remove one of the steel legs.  There are two sections on this steel leg that are about 3/4" long.  Use the wire cutting pliers to cut these two 3/4" long straight sections out of the leg.  You now have two chromed steel dowel pins.  

You are ready to assemble your new Veos wαllet.

Step 4: Veos Wαllet Assembly

Okay, gather up the printed wαllet, rubber band, dowel pins, and frosted window.

Push the rubber band through one slot from front to back.  Pull the rubber band through about 95% so a small loop is left on the front side of the wallet.  Slide the first pin through the rubber band loop.  Next, pull the rubber band taut from the back.  This seats the first pin.

Now, pull the band taut again, use the screwdriver to push a small loop of the rubber band through the second slot.  Push the second pin through this rubber band loop.  Lastly pull the main loop of the rubber band loop taut to seat the second pin.

Step 5: Enjoy Your Veos Wαllet

Slide a picture, or I.D. into place then slide you cards into place.

LAST NOTE:  Play around a little, the top card can be slid out about 1/2 way and then run through a retail card reader without actually removing it.  Then just push it back in, quick and easy!

Enjoy your new Veos wallet !!!

    Keeping the card in a dedicated plastic envelope is way less cumbersome : this is much too thick and somewhat useless as it is as thick as a small wallet (you don't have to stuff your wallet with unnecessary cards so it remains slim and not thicket that your contraption).
    Nice job though !…

    Hey Vincent,

    You make a great point about the wallet staying the same thickness no matter how many cards are used, thanks! I am working on a rubber band style wallet that expands and contracts depending on how many cards are used. I should have it posted in the next two weeks.

    Though, that said, the Yetttos wallet is as thin as anything more than just a rubber band.

    thanks again for the great feedback, I just had not really realized the downside of the wallet staying the same size.

    Waiting for your next instructable then !…
    However I should have added it was a nice piece of engineering.
    Cheers !

    Yup, pretty out there huh? Though there is a story, and you can discover the story at http://www.veosllc.com.

    Security Warning!
    FYI: This is not a good thing to use with smart cards, smart drivers licenses, or IDs that have RFID chips in them. Those items can be scanned remotely and need to be housed in the protective sleeves that come with them.

    One last thing. It would be a good idea to place soft tissue paper between multiple credit cards to prevent the magnetic strip from being scratched. Also insure that no two magnetic strips come in contact for a lengthy period of time as this can cause the two strips to be erased. I've heard of this happening.

    Tovey is correct, these 3D printed wallets do not protect from RFID theft.

    However, I do sell CNC machined Aluminum versions at http://www.veosllc.com. These metal versions do protect from RFID intrusion. Check them out for purchase!

    Sorry but this is unnecessary spreading of FUD. 99.999% of wallets in existence today don't protect against RFID reading. So yeah, keep them in their sleeves.

    Also, I have several credit cards scratched and scarred that still scan perfectly. Scratches aren't a big deal so long as they are not removing a perfect vertical bar from the magnetic strip. Using soft tissue to relieve scratches would defeat the purpose of this wallet which is ease-of-use.

    I have also anecdotally found that as long as two strips aren't sitting right atop each other for a long amount of time, they wont demagnetize each other. Just keep all your cards oriented the same way, and the gap created by the rest of the card will keep any chance of demagnetization to a very narrow probability.

    I replied using the reply link and it didn't post. ???
    So I'll re-post.

    There is an ancient proverb that goes something like this:
    Better safe than sorry!


    Thanks Andrey!

    I sort of made the 3D printer. It is a Printrbot brand, a self build kit that was available on Kickstarter.
