7 inch LCD "Mini Monitor" enclosure for generic module off Aliexpress Parts: OTS: 7 x M3 x 20mm pan head bolts 4 x M3 x 10mm pan head bolts 3 x M3 x 8mm pan head bolts 4 x M3 nuts 3 x M5 x 12mm bolts 5 x M5 nuts Printed: 8x pcb spacer 1x bezel 1x core 1x back shell Assy: 1) Print everything off 2) Clean up pieces, remove brims etc... (some de-burring of larger hole id's may be needed) 3) Tap all holes to M3 x (chosen pitch) I used M3 X 0.5 (HINT: if power tapping SLOWLY! with drill. Use IPA or water as coolent as PLA likes to melt!) 4) Press fit M5 nuts into back shell & attach switch PCB (2 x M3 x 8), aligning switch actuators. 5) Fix controller PCB to core (add a spacer on either side of PCB, use 4x M3 x 10 bolts) 6) Place LCD into core & feed through FFC. Secure bezel with 1x M3 x 8 bolt 7) Connect FFC & switch cable to controller PCB 8) Secure back shell with remaining 7 x M3 x 20 bolts. 9) Assemble & attach stand if needed with M5 x 12 bolts. Ensure stand bolts do not touch PCB! Issues & Improvements: Some thermal issues noticed when running the display @12V: Back-light flicker noticeable after running for 24 Hr in >30 deg C ambient. Possibly poor ventilation in design...Perhaps heat-sinks needed on driver IC or just run at lower supply V. Stand & mounting option is over complicated. Would be nice to squeeze holes for VESA mounting into the back shell...looks to be just enough space. Viewing angle of my LCD is awful when orientated with input cable entry facing down (FFC up). I ended up flipping the whole thing 180 degrees as shown in photos as this was discovered during assembly. Recesses in core for PCB mounting need adjusting for nut retention. Criticism is appreciated & Enjoy.
