ALL TPU / FLEX Customizable Luggage Tag and Strap

I liked the PLA / PETG luggage tag, but it was rigid and tended to be harsh when it hit hand.  The hard print models can also break.  This one may not have that problem.

This new SCAD generated model is designed just for the attributes of flex.  This new tag preserves the ability to have a closable cover and adds an extremely strong fully flexible strap.

It took awhile to come up with a tag cover you could close and still open on demand.  The closure button has turned out to be easily operated.

I don't think this print with the cover would work in hard plastic.  If you turn OFF the cover it removes all the flex attributes and that could be printed in any plastic desirable.  With the cover OFF you can still print text on the back.

Usage in printing the Label:

PRINTING:  No special perimeter, fills or other.  You will require a TPU profile with appropriate settings to survive all the retractions required when printing letters.

1. In openscad I recommend using the customizer interface.  Your choice.  Remember to save your data profiles.
2. Enter the desired text using the lines top to bottom.
3. If you want text on the back enter something in that field.  Leaving it blank will render nothing on the back.
4. Use the CARD DIMENSIONS XY menu to size your card around the text you have entered.
5. Use the Front Text Adjust to set your font size if desired.
6. If you are printing the back, rotate the a view of the back and then use the BACK TEXT ADJUST to orient and align the back text.
7. TEXT NOTES Printing TPU may be new.  Printing TPU letters may push you to a level above beginner.  Some strategies for printing good letters.
   1. To print letters we need to stop the TPU ooze and do a good restart frequently.
   2. I don't know how well TPU will do with letters if your are not direct drive filament feeder.
   3. Slow the print down when printing letters.  This will allow the time for the ooze to stop.
   4. Lowering your retraction speed.  Fast retraction can cause the TPU to stretch in the extruder gears making the feed slip or stop as it looses contact with the TPU.
   5. Make sure you use a thick font with few accents. 
      1. A font with consistent thickness.
      2. Avoid single wall letters as the slicer may drop them from rendering.

Printing without a lid:

1. The LID options the PRINT LID is relevant.  The rest of LID OPTIONS and the CARD DIMENSIONS OTHER are if you want to mess with thickness's and such.
2. You can print the card with INVERSE text ( embedded text).   To be readable it tends to want a larger font. 
3. Once your card looks good F6 to render

TPU STRAP

There are a couple of strap options and strap connector options.

PRINTING: I recommend printing your strap with 5 VERTICAL PERIMETERS.  This will give it the strength it needs to hold the pins and reduce stretching.

1. To better hold the flex cover closed there is a strap with "FINGERS".  The printed card will go in the fingers facing the words to help keep in closed.
   1. You can opt to not use the fingers.
2. There are two connector options. 
   1. SNAP in is a one time use snap together connection.  If you have issues pushing them in the slightest bit of lubricant on the crown should do the trick.
   2. SLIDE is designed to allow you to put together and take apart the strap.  Its not as strong as the SNAP and for best results the BAND COVER should be printed and slid over the finished connection.  That will make the SLIDE super strong as a connector.
      1. If your slide strap binds shut at print, simply cut the slot free with a razor blade.
3. Choosing a BAND cover for the SLIDE strap.
   1. You only need one band strap
   2. There are TWO thicknesses. 
      1. 1mm with the 5 vertical perimeters will have a little stretch and lots of strength.  I recommend this size.
      2. 1.4mm thick with 5 vertical perimeters will have almost no stretch and is quite strong.  Overkill for your strap.
   3. There are TWO styles.
      1. With a handle (for those that need something to grab onto when sliding it on)
      2. Without a handle
   4. There are three diameter sizes.
      1. the COMFY size should fit fine, but if yours does no there is a LOOSER one and a TIGHTER one.
   5. Assembling the SLIDE VERSION
      1. Remember to put your BAND COVER on first
      2. Overlap the tips with the SLIDE holes and push together, OR put one in through the slot and slide it into place, then do the same with the other.
      3. Slide the BAND cover over the finished connection.

If you need a strap longer than 156mm let me know.  I will add some to the library.

** CAUTION **: The straps have now tangle / tension release and are not designed to be a toy for kids.
