14 Printable LM8UU linear bearings test plate

thingiverse

To evaluate various LM8UU designs, I compiled 14 STL files in one plate. Some models may be fragile with a 0.5mm nozzle due to lack of infill between shells. I only included ready-to-print LM8UU files; others require repair or customization. Test results and material experiments are forthcoming, including PLA, polystyrene, PET, polycarbonate, and potentially nylon (though concerns about stickiness exist). To assess the designs, follow these steps: 1) Print a plate with a layer height of 0.25mm or less; 2) use an 8mm rod to test fit and play; 3) choose the best-fitting design for printing replacement bearings; 4) run your printer and report on usability and long-term wear.
