i participated in and round 1 and 2 and from what i have seen out of all the rounds, round 2 was the fastest turnaround, it took less than 7 weeks to fulfill. i think there are some challenges with this round 4 group buy, the added assembly option and top plate makes me wonder how they are going to handle it, will they ship the parts-only orders first or ship everything out at once.
If i didn't already have 3 of the suckers and custom acrylic layers i would be all over your case czarek, you did good and i hope you are able to move forward to a sale. and for US people the mechanicalkeyboards.com ergodox pcb is a good deal and supports cherry stabs.
I think its not exactly the litster layer case that is the problem, it is the all-clear acrylic, the clear acrylic on the massdrop case is just a bad move for massdrop when solid color acrylic doesn't appear that much more expensive and looks so much better.
its also shocking they still don't provide proper feet and use normal nuts instead of cap nuts that wont scratch up everything.
