Yes, I have a 3D printer, and could easily prototype them, but fitment testing, specifically wires, is a whole other issue that I could only address with an on-hand unit. If you would pay shipping both ways, you could have the endcaps no charge. DM me if you're cool with that. I had posted, looking for a dead unit for fitment testing, but I guess they're too well built.
Something to note is that I won't be able to do thermal testing, as my current WS tops out at 135W of draw max, and I don't have a 400W DC-ATX.
So yeah, I need one just for fitment.
