chain mail and chain - updated 3.15.2013 by tc_fea Aug 29, 2012

Description

One of the photos shows that the "long" chain is 44 inches long when stretched out. file: chain_8_large_120828c.zip

The "large" .stl's are much larger but will take much longer print.

The .stl's are zipped due to the large file sizes

All of these objects fit easily onto a 100mm by 100mm build platform with a some room to spare.

The large chain print is X 89mm by Y 89mm and should fit on most platforms.

The large chain mail is X 79mm by Y 89mm.

Thank you. I tried to design so that it would work on as many printers as possible. :)
Wow, this works really well!  Even on my Makerbot with an Automated Build Platform
Thanks for the idea. 36.6 Mb ASCII became 2.42 binary. :)

Instructions

3.15.2013 - added a larger "connected" mail with two more rows of links in each direction
mail_8_very_large_130315b.stl
mail_8_130315b.skp

STL FILES
===========

The .stl files with "_nf" in the name are binary files and are much more compact than the ASCII files previously provided. Cymon: thank you for the recommendation. I will be deleting the ASCII files after I convert them to binary.

chain_8_large_120828c_nf.stl is 43 link chain binary file (2.42 Mb)

chain_8_short_120829a.zip is a 7 link chain (shown in photo)

mail_8_large_120828a_nf.stl is a 56 link chain mail binary (3.15 Mb)

mail_8_large_120828a_connected_nf.stl is a 56 link chain mail binary. The first and last rows are connected by 1 mm thick layer to keep the chain mail from tangling. (3.15 Mb)

mail_8_small_120827c.zip is a 10 link chain mail sample (shown in photo)
mail_8_large_120828a_connected_nf.stl is a 10 link chain mail sample. The first and last rows are connected by 1 mm thick layer to keep the chain mail from tangling.

SKETCHUP FILE
=============
chain_8_120829b.skp - sketchup file for short and long chains
mail_8_120829b.skp - sketchup file for all chain mail versions

One picture shows the "short" and "small" test versions of chain and chain mail.

A photo of the 43 link chain is shown as printed.
For reference the build platform is about 150 mm by 150 mm.

additional pictures are provided for versions not yet printed.

nice print, TheCase
The .STL would be smaller if they were saved as binary STL instead of ASCII.
tc_fea - in reply to maxy
the export plug in for Google Sketchup wrote as ASCII. When I centered it in Replicator G, it still came out as ASCII.

Do you know how to convert it to binary?

thanks

Run it through cloud.netfabb and you get it cleaned up and in binary. I just run everything through cloud.netfabb now.

thank you. I will have to try that. A friend mention netfabb a few months ago, but I forgot about it.

MeshLab can do it. Slic3r can do it. The Cura project planner too, but it also reduces the resolution. Blender can do it (import an STL, select the object by right clicking, export STL).
