I have plenty of spare tops so I really should experiment with that. I figure I should start with 0.02" since that's the width of the slots and then try your 1/32". I've sort of moved on from the block for now since the prototype actually works (surprisingly), but I'll eventually get back to it. I really need to get the case design sorted out so I've been back to working on that. I'll figure it out one of these days .
I've been teaching myself Solidworks. Flow modeling was relatively easy to get to work, next up is figuring out heat transfer simulations.
The animation got sped up a bit when making it into a gif but it is kind of mesmerizing. It's neat how water accelerates through the channels and then creates a vortex on output. I hope to experiment with minor tweaks to improve performance once(if) I figure out the thermal simulations. I'll make all the tops you want, however, you're on your own for the base . Actually Solidworks has some pretty good tutorials either online or within the program. Between that and the occasional youtube video I think I have a reasonable grasp of basic modeling and assembly, of course I'm going to need a lot more practice. As for that animation, it was made with the FloXpress Wizard which is actually pretty easy to figure out using their tutorials. But FloXpress is really only meant to be a quick and dirty simulation, the Flow Simulation add-on is a whole different beast which I'm just starting to play with.
