Does anyone else have this air assist head from Saite Cutter on EBay?

Does anyone else have this air assist head from Saite Cutter on EBay? Does it assemble in the order I have it shown? My issue is the 2 washers. One looks to hold the lens and the other to keep the lens from moving when air assist is used. The problem is that with everything assembled the washers restrict the vertical movement by a good 5mm.

I have that head and mine didn’t come with washers at all. You just pop the lens in the cone and screw down the insert and the lens doesn’t move.

The washers are for the stock 12 mm focal lens ,not needed if using 18 mm focal lens

thanks @K1111 and @Phillip_Conroy . I guess I should have taken out the 18mm lens out of the packaging and did a test fit. I thought I was being smart by keeping it in wrapped up until I was ready to mount. Doh.

@K1111 @Phillip_Conroy Do you guys happen to have a design of the mount that holds this Saite laser head? Figure there has to be one floating around here that people are using to mount this new air assist head.

@Bill_Keeter I don’t. I’ve got a custom bed so my files wouldn’t work for stock machines.
