I neither have the time nor intellect to write code for OpenSCAD, but I sure appreciate the effort
that has gone into it. 

I have a friend who does a lot of volunteer shareware software development. His programs get downloaded about 20K 
a month, but in the 12 years he’s been doing it, he’s gotten about $200 in total whereas on the other hand the request 
for new features or complaints about how his programs don’t do one thing or another are endless. I know for a fact he’s pretty 
pleased when he gets that very infrequent email of thanks and/or praise.
So for part I try to let the developers know how much I appreciate the time and effort they put into this project.

I know OpenSCAD isn’t perfect, and I’m pretty sure the developers are even more aware of its imperfections than I am, but
for a variety of reasons OpenSCAD is my development environment of choice and I’d hate to see it wither and die.

Secondly… there’s cash. :) To show my support I make a (currently very modest) monthly donation to OpenSCAD which
I hope to increase as my own resources permit. I’ve spent far more on a 3D printer than I’ve spent using the program that
I consider indispensable to creating object to print on it… I don’t think that’s quite right.

Thirdly, there’s bounties and I know if I’m really serious about an extension or feature, I could offer a reward. I note that some
feature requests with a bounty will sometimes even see others joining in to up the ante and make it even more
worthwhile for someone with the knowledge and expertise to actually do the work. Granted most of the bounties offered 
seem to be in the < $50 range… but I wonder how excited one of the developers might be If one were to offer something like
$200, $500 or $1000 for something to be implemented.
Something at that level might be out of my range, but I’ve been toying with the idea of offering a bounty that would serve
as a serious thank you for the time and effort it would take for a feature I’d very much like to see.
