Feet, Glides & Bumpers replaces furniture hardware in any size: leveling feet, chair-leg glide cups, caster cups, and door bumpers, each sized to the millimeter. For leveling feet, a standard metal hex bolt drops into a captive pocket and carries the load — the plastic only positions it. Pick the Type, then enter the one measurement that matters: leg diameter for glide cups, wheel diameter for caster cups, bolt size for feet. Fit Clearance fine-tunes how snugly a cup grips the leg — adjust in 0.2mm steps from the default. Every part prints support-free exactly as exported, four to a plate. Use PETG with four or more perimeters for anything that carries furniture weight; it shrugs off load and scuffing far better than PLA.
