I did it.
After months of designing, machining, tapping, threading, soldering, troubleshooting, reworking, fretting, printing, fixing printers, testing, and fretting (yeah, it's in there twice). I've finally boxed up the first two Delta Throttles bought on our Etsy store.
I've learned a lot along the way, and we're not even talking about the part where I built my own CNC machine from the ground up. I've got a few tweaks I can do on the next builds to make the process a bit smoother. I've got a box full of extra bits I machined while cutting things in batch mode, and as luck would have it - we had another order come in yesterday morning.
I hope the two folks enjoy their throttles!
