* OHM2013-Logo. If you wish to use other logos please use the original
|
|
* file. All other parameters were not modified.
|
|
*
|
|
* This file was modified again by djerun to use the catars printed
|
|
* by c3cat: https://www.printables.com/model/35076-cat-ears
|
|
* as the logo and optionally allow use the ears from
|
|
* https://www.thingiverse.com/thing:5029374
|
|
* printed at scale 0.2 as glue-ins for additional ears.
|
|
*
|
|
* `Ohren_4.stl` and `catears.stl` need to be placed in `../stls/`
|
|
* for the symlinks to work otherwise `catears.stl` needs to be placed
|
|
* at `./catears.stl` and `Ohren_4.stl` at `./catear.stl`.

|
* Creates one instance of a bottle clip name tag. The default values are

|
|
*
|
|
* Parameters:
|
|
* ru: the radius on the upper side of the clip
|
|
* rl: the radius on the lower side of the clip
|
|
* ht: the height of the clip
|
|
* width: the thickness of the wall. Values near 2.5 usually result in a good
|
|
* clippiness for PLA prints.
|
|
* name: the name that is printed on your name tag. For the default ru/rt/ht
|
|
* values, this string should not exceed 18 characters to fit on the name tag.
|
|
* font: the path to a font for Write.scad.
