VisePads with PCB channel

Wanted some visepads that would allow me to grab a PCB more easily. I have a helping hands, but that's too small for doing multiple piece batches. These pads are smooth with a 2mm channel near the top

Overall width: 110mm
Space between holes: 60mm
Hole dia: 6mm
Hole cap dia: 10mm
Hole countersink depth: 5mm
