Screw Size for brass inserts on the upper tube clamp on Onefinity

General

What is the screw size for the brass inserts on the top tube holder? I need to add a riser so my 2.5" dust collector hose clears the Z stepper motor. The hose is ceiling mounted and catches on the Z stepper when the spindle is at Y max position (back position).

I believe their like 3/32nd screws if you’re trying to DIY something, otherwise there is the 90degree base, arm and attachment as seen in at the bottom of this article. UHC 90 Degree Stepper Base

Or if your spindle mount doesn’t clear the top of the gantry, theres this Flush Base for Onefinity
