CONCEPT ONLY: PCD50/PCD76 phase45 and slot9.5x5.5 assumed.
Corners flush to motor, moved 2.5mm outward from slot midpoint; 4mm screw nominal slot-end clearance 0.25mm.
Pillars 0.5..10.9mm and panel 10.9..14.1mm; closed Ø4.4mm bore.
M4x20 nominal screw engagement in motor 20 - 14.1 = 5.9mm, true tapped depth unknown.
Pillar cylinders Ø9 extend from z0.5 to 14.1 and merge through panel; clipped at z0.5..3.21 against expanded corner projection 0.2mm.
Minimum low-side wall near angle ~0.54mm theoretical, no print/strength guarantee.
Estimated head bearing material by sampling (mm2): 24.00, 24.00, 24.00, 24.00
Selected positive-volume intersections >0.001mm3:
none
Tool envelope Ø7.5:
M4 tool 0: no checked obstruction
M4 tool 1: no checked obstruction
M4 tool 2: no checked obstruction
M4 tool 3: no checked obstruction
76 M4 tool -1,-1: no checked obstruction
76 M4 tool -1,+1: no checked obstruction
76 M4 tool +1,-1: no checked obstruction
76 M4 tool +1,+1: no checked obstruction
