Thanks again for all the interest!
To give an update, the color matched filament is now officially gone. The last set was finished last night. I'll keep an eye out, but assume that white is the only option going forward.
Based on current interest/throughput, I have about 3 or 4 more days of producing V4 w/glass cup versions; I'll then start printing and fine tuning the V4 with 419 cup, then will do the V3 versions. Those version should go much faster as I don't anticipate a ton of orders up front. But I've been surprised before.
I appreciate all the patience, and support!
