stopper

|---|---|

The stopper: follows the channel's rounded bottom, clamped by an M3 set screw pressing against the web |
The stopper is 13 mm long: the gap between the rail end and the wall is about 15 mm, and it goes in from that end.
Status: done. Printed and fits the rail.
Hardware
-
1x heat-set insert, CNC Kitchen M3 x 3 short, per stopper. Press it into the 4.0 mm hole in the flat top face with a soldering iron, flush with the face (it must not stand proud: that face rests against the rail's web).
-
1x M3x5 set screw, flat point (DIN 913 / ISO 4026), per stopper, screwed into the insert from below (the insert's hole runs through the part). Turn it in until its tip is just below the top face before inserting the stopper into the rail. Tighten with a 1.5 mm hex key through the slot, snug only.
(A screw cutting its own thread into a 2.5 mm hole did not hold.)
Print sheet (suggestion)
Print the stopper in the orientation it comes in the 3MF (flat top on the bed); no supports needed.
