ASSEMBLY STUDY, all dimensions mm.
50 mm screws ARE NOT in the current product; heads are only assumed envelopes Ø7 x 3 at z=0..3.
Corner/rail move ±2.75 in X, encoder, motor and 76 mm fixing studs unchanged.
Oval slot 9.5x5.5, M4 male diameter 3.9 assumed; outer limit clearance 0.05.
50 and 76 mm hole-circle angular phase 45 degrees is assumed.
Screw head zero separation may be intended contact; positive volume indicates interference.
50 mm head versus same-quadrant corner:
Corner0 (-17.68,-17.68) before common=22.4670 after common=0.7143 mm3; after separation=0.0000 mm
Corner1 (-17.68,+17.68) before common=22.4670 after common=0.7143 mm3; after separation=0.0000 mm
Corner2 (+17.68,-17.68) before common=22.4670 after common=0.7143 mm3; after separation=0.0000 mm
Corner3 (+17.68,+17.68) before common=22.4670 after common=0.7143 mm3; after separation=0.0000 mm
Shifted corners and rails versus existing components (>0.001mm3):
none in checked pairs
50 hole 0 access envelope Ø7.5 from z=3.01..25.01: EncoderBracket 141.372mm3
50 hole 1 access envelope Ø7.5 from z=3.01..25.01: EncoderBracket 141.372mm3
50 hole 2 access envelope Ø7.5 from z=3.01..25.01: EncoderBracket 141.372mm3
50 hole 3 access envelope Ø7.5 from z=3.01..25.01: EncoderBracket 141.372mm3
OPTIONAL Ø8 access holes in encoder bracket, only a concept, NOT a released print file:
Assumed 50 mm head Ø7; fastener head diameter, tool, screw, and wiring need physical verification.
Ø7.5 access envelope candidate:
no checked obstruction
