Zip Top Bag

by PrettySmallThings, published


Another design in my pursuit of 3d printed purses - though this one serves equally well as a pencil case.

It's a quick print, a sleek design, and functional to boot. The zip top closure makes a satisfying zippy noise, and holds everything closed nicely. Kudos to gabielfp's awesome roll top box and emmett's bracelet that served as my inspiration.

Watch assembly and demo:

I've made subtle changes to the fabric edges, for better alignment with the side bands, since taking the photos shown in this post. Close ups of this area appreciated by anyone who makes a print.

There are lots of options for other sizes, orientations, or the addition of a chain in future releases.

*Update* I've added more sizes to accommodate other platform sizes: 140x223, 140x195 & 140x145. I have also provided 95mm x 95mm test piece for anyone looking to see the concept in action without printing the full project.

There are two options for printing the fabric:
Slice at .2mm layer height. Be sure the infill is laid down perpendicular to the design lines in the fabric. Or, slice at .1mm layer height, with infill rotated 45 degrees.

I sliced my project at .2mm, and like the results. .1mm should also work and be somewhat more flexible. Adjust "Infill Begin Rotation" under Fill in skeinforge to change the direction of the fill in your first layer.

Let the fabric cool before pulling off the platform to reduce breakage or warpage. Use glue or acetone to adhere side pieces to main fabric. Fill with prized possessions, slide on closure, and go!

Nice work on how the sides snap on!

I am going to learn a lot with your work. It is incredible. Thanks

how do you get the material flexible and what software did you use to design this im new and looking into getting a makerbot replicator 2

PrettySmallThings on Apr 20, 2013 said:

Thin layers of ABS and PLA are naturally flexible. I designed this in autocad, but there isn't anything special about the geometry - you could design this in any solid modeling program without much trouble. Creating the design takes time and experimentation - but the choice of CAD program doesn't have much to do with it in this case.

oh my gosh!!

Perfect print on a Replicator (6.2 firmware).
My settings:  for the fabric 100% infill; .25 layer height, 0 shells and NO raft at 100mm/s and travel 150mm/s
The sides with 20% infill and 0.3 layer with a thin raft (=in skeinforge 1 layer base and 1 layer interface, removal is easy like that).

PrettySmallThings on Dec 1, 2012 said:

Glad it worked for you!  I print without rafts in general unless support is required.  Thanks for sharing your print.

What's the difference between the clasp in "ZipBag SidesClasp" and the "Tester Clasp"? Just that it's separated out?

PrettySmallThings on Dec 1, 2012 said:

It's shorter.  The length on the actual version helps the sides stay together better - but since the test swatches aren't actually a functional object, I shortened the clasp to save a little plastic.

Thanks for the different sizes

terramir on Nov 8, 2012 said:

ehh got a problem most 3d printers including mine have a print area that is no bigger than 200mm :(

PrettySmallThings on Nov 8, 2012 said:

200x200?  As I said in the instructions, the 140 dimension is fixed, but I can easily shorten the 225 on request.  To 200? To 190?  I have yet to find a good guide on the internet about typical platform sizes - I think mostly there isn't a standard anymore - but if you know of a resource, I'd love to see it.

Beautiful! :)

I love it! Nice work. I work with CA glue a lot, latex gloves are a must!

PrettySmallThings on Nov 8, 2012 said:

You know, I never bother with gloves, but it's not a bad idea for.  Ventilation is also a must!

Amazing. Absolutely amazing. I want to print one of these out and I don't even have a reason to.

Too cool

henrik991 on Feb 17, 2013 said:

I thaught the prints came out very hard. Is it really possible to bend this, so that the purs is rounded?
(New at this.. My printer is on its way.. 4 weks left)
