In that case, forget injection molding and think extrusion. You've got
something that's basically like a big T05 heatsink, so you should be
able to extrude as a complete part (no snap together) and then slice
into the appropriate lengths.

made by experts and the price goes up accordingly. I want to do it all 'in

get some epoxy parts out of it soon.

You could also just lathe and mill it with a 4th axis, taking a solid
plastic rod, bore the center hole on the lathe, then put in 4th axis on
the mill and mill the fins. A 24" rod should yield like 45 parts.
--Not set up to do this either. Sigh..
