T-Slot Slide - for use by sliding in lengthwise along the enclosure aluminum extrusion

T-Slot Twist - for use by inserting sideways and twisting into position. Intended to be a tight fit and to only twist one way. Flip the part over to twist the opposite direction. If too tight, you can sand lightly or scale down slightly on the width

Clipped - for use by clipping into place. For this one I found it important to use a narrower line size to avoid having the slicer cut the point of the slips too short

Bolted - for use on the existing M4 bolt holes in the linear modules or enclosure
