Flat Pocket Whistles - WAISN

UPDATE 2/1 - 5mm V2:

Similar changes listed in the 1/28 - 3mm V2 update have been applied to the 5mm whistle, the updated versions of which are also labeled V2. 

Versions: 3mf (recommended) and stl (in folder) are both available. The 3mf files are all available in both light and dark versions (referring to the whistle color), and are pre-coded for printing the opposite color first to prioritize the text during the first layer. The 3mf files also allow you to easily modify the text for other cities/states.

Timing: 
 - 3mm will print 20 whistles in just under 2 hours.
 - 5mm will print 20 whistles in just under 5 hours.

As noted below, double check your settings to ensure that, whatever filaments you are using, you are forcing the text to print first on the first layer.

UPDATE 1/28 - 3mm V2:

After much arguing with my slicer and test printing, an improved version of the 3mm is now available. I'll be working on making similar updates to the 5mm very shortly. Original versions will be moved into a folder, with updates labeled with _V2.

Font Fix:  V2 prints more uniformly and consistently, with better individual character definition and less stringing. 
Prior version used a font with inconsistent line width, which was especially notable in the 3 and 4 in the phone number. V2 uses Calibri Light with a high level of boldness and increased character spacing (200pt/20pt for the phone number, 210pt/100pt for the website). Overall, these font changes allow for a larger font in the same amount of space, while guaranteeing each line can print in full when using a .4mm nozzle.

First Layer Filament Sequence:  V2 prints the website with reliable character definition, without fighting the slicer over text depth on the bottom layer.
Prior version used auto sequence, which initially turned out well (original V1 photo) but was increasingly printing with extremely poor legibility as the file defaulted to printing the bottom of the whistle before the website text. If you've run into this issue from V1 you can fix it with a very fine permanent marker, but it's not ideal. V2 3mf sets the object plate settings for First Layer Filament Sequence to 'Customize' to force the text filament to print first.
NOTE: The 3mf is pre-coded for this instruction based on the light/dark settings. If you use the STL file then it will have defaulted back to Auto and must be manually reapplied. Double check your settings to ensure that, whatever filaments you are using, you are forcing the text to print first.
NOTE: I highly recommend a bit of glue to help the letters stick. If your plate is more static than stick, the letters may wander off.

Versions: 3mf and stl both available.

ORIGINAL INFO:

The 5mm whistle includes both the phone number, website, and whistling instructions.

The 3mm whistle has the phone number and website only.

3mf files keep the WAISN info and instructions as separate objects for easy remixing.

I don't really recommend ironing as it can muddy the text, as shown in the original black 3mm photo. The 5mm responds better to ironing if you just apply it to the top layer of the whistle body and don't iron the text.
