Measure your rail or slot width, set the fit from snug to loose, and get a printable clip that snaps onto your extrusion. Editable in the builder afterward.
A clip that snaps onto a rail or T-slot extrusion. The Fit slider sizes the channel so it seats snug to loose on your exact rail.
Width of the rail or T-slot lip the clip snaps over. The Fit slider adds clearance on top.
How far the clip wraps down the sides of the rail. Deeper grips more firmly.
Length of the clip along the rail. Longer holds more securely.
How loose the printed part sits on the thing it mates with. Looser prints fit more easily.
Snug adds 0.10mm, Normal adds 0.25mm, Loose adds 0.50mm to the surface that mates with your object, so the printed part clears it without extra sanding.
