ShortStack Wallet - slim, ultralight, no-sew

ShortStack weighs just .5oz (14g)* and is 0.14" (3.6mm)** thick fully assembled

No Snags! No sharp corners and no bulging elastic to get caught in a pocket.

No sewing! CA glue (superglue) secures elastic in place surprisingly well!

Put a logo on it!  Right panel is a blank canvas!

What you'll need

• CA glue (superglue)
  • recommend thick or gel type
• 3/4" (20mm) flat elastic band
  • Length depends on elasticity and preference.  ~4.6" (118mm) with my elastic and it is very tight on 4 cards.
  • IMPORTANT NOTE:  Not all elastic is the same! Some heavy-duty elastic measures 21mm x 1.1mm and due to designing the model to save every mm and gram I have created multiple models to account for the measured differences.

Print Settings

• Layer Height: 0.2mm
• Supports: recommended
  • bridging may droop too low without support
• Orientation: face down recommended (see stl orientation)
  • Face up is possible, though bridging that may cause the top surface to droop with so few layers.  I suggest a dedicated support material w/ 0 top z distance to give the best surface finish.
• Materials: All
  • CA glue (superglue) may not adhere well to some PETG

Assembly

1. Taking the left panel, feed an end of elastic from the outside to inside.  Pull just enough through to rest in the notch.
2. Add a thick coat of CA glue to notch face.  Fabric will absorb glue, gel/thick type CA glue helps it stay in place. 
3. Fold down elastic onto glue and apply pressure
4. Take other end of elastic and feed it through the remaining opening, Make sure there are no tangles.  Elastic loop should be on the outside side.  See photo for reference
5. Repeat step 2-3
6. Flip the elastic to inside.
7. Insert right wallet panel under elastic
