Description
OpenSCAD parametric script to generate a 3D printable tie. This differs from most others in that it allows you to easily make diagonal stripes in the tie by angling the tie, slicing it into sections and swapping filament colours. It also is assembled using strapping/webbing and a more complex neck piece which should allow it to be worn in a more standard/traditional way!
I have seen several tie designs on thingiverse recently and I've wanted to make one myself. Specifically I have been mystified as to why I've not seen a wide strapping type material used to hold the pieces together and wrap around the neck comfortably. Equally I am amazed that no-one (as far as I have seen) has made a diagonally striped tie using filament swapping. This design is inspired by the other ties recently on thingiverse but is all original work.
@version attempt 3
@date 2012-06-09 ISO Standard YYYY_MM_DD format
@todo
make parametrically positioned mouse ears
@warning
This is a VERY long print (+5hrs on Thing-o-Matic)
filament changing or multi extruders will be required to get stripes!
I have not assembled one of these yet so am not sure how it will work out
In order to have the bottom part NOT fall off you will need to ensure that the little angled cutout at the end is fully in the bottommost part fo the tie (you may need to manually adjust its position to be so)
@note
Changes from previous versions:
attempt 3a
- made slightly narrower so that it would fit in a thing-o-matic (expected print time is over 5 hours O_O;
attempt 3
- integrated linear_extrude into tie module
- integrated cutout and other 2 components (neck thing and actual tie)
attempt 2
- made parametric angled sliced tie and neck thingy with attempt at generting cutout for webbing internally
@attention
Copy left (I think... basically you can do whatvere you want with this, you don;t have to acknowledge me (although that would be nice!))

Instructions
0. Download Openscad script and set the values in the *user*variables* section to reasonable values for a printable tie of your dreams
1. Generate .stl
2. Print all the sections (insert different coloured filaments where you want your stripes to be)
3. Clean out plastic in all the recesses and cutouts
4. Thread strapping/webbing through the internal cutouts in the tie and neck piece leaving enough space for your neck and some extra for tightening
5. After pulling one end of strapping through angled hole at bottom of tie and other end back through the bottom of the neck piece fold them over and either stitch or heat seal together so that can't go back through the holes
6. Wear a tie like-a-boss

First print attempt was overall successful. I swapped from blue to white to black ABS filaments. Loading the white filament was tricky as it was much thicker than the others and variable in thickness so the extruder tension had to be adjusted constantly for this section. Even so it got stuck a few times, hence this layer is rather thin and weak in places and 2 sections of the tie broke at this point when they were removed from the heated build platform. These sections were re-glued using ABS glue/acetone.
Some issues with the design were also noted:
The plastic covering the back of the internal cavity was so thin in places that it warped and cracked so I may change some of the settings to prevent this. The heat reflecting panel fell off the back of the printer late in the print so the neck piece (w
hich was facing backwards) warped and cracked slightly, but this was fixed using ABS glue/acetone.
After some cleaning up of the edges and internal cavity with an emory board/nail file the 25mm/1 inch wide webbing was relatively easy to insert through each section of the main part of the tie. Howev
er it is very hard to thread such wide straps through the neck piece as they are slightly thicker than I though and they have to turn through about 30 degrees as they pass through it and over each other, I may make this angle less severe! Also I noticed that the bottom-most stripe is essentially dou
bled up and the tie is a bit short... I'll probably print a plain black fill in piece that can go between the bottom 2 sections to remedy these errors.
