|
* Parameters: *
|
||
|
|
* There are 9 parameters to this model as follows, *
|
||
|
|
* *
|
||
|
|
* height : The height of the helix in mm. The total model height will be *
|
||
|
|
* this height + thickness/2 +1-2 *
|
||
|
|
* steps : This setting will control the granularity of the design, a lower number*
|
||
|
|
* will result in smoother model but take much longer to render *
|
||
|
|
* radius : The radius of the entire toothbrush holder *
|
||
|
|
* thickness : The radius of the helix spirals *
|
||
|
|
* brushhole : This is the diameter of the hole the toothbrish will sit in *
|
||
|
|
* tubethickness : This will be the tube wall thickness of the toothbrush holder *
|
||
|
|
* floorthickness: The thickness from the bottom of the model to floor of brush tube *
|
||
|
|
* drainholediam : The diameter of the drain hole at the buttom of each brush tube *
|
||
|
|
* brushes : Total number of toothbrushes the holder will have *
|
||
|
|
* *
