Hey everyone, we are modifying our cascade to use a single central large spacer instead of small ones on each side. The design is solid, but we are struggling to source a spacer with the exact dimensions required. Required Dimensions: Height: 0.5" ID: 0.17" (Clears a #8 or M4 screw) OD: **0.70" (**This is the tricky part, as it really must be: 0.68" - 0.72") McMaster-Carr only seem to stock 5/8" (0.625") or 3/4" (0.75") OD, which will not work for this setup. Does anyone know of a supplier or specific link where we can find a spacer with these dimensions? If this is too custom, what alternative design or approaches would you recommend?
I suggest getting the 0.75 ones and sand it down with a file/ sandpaper with a drill.
