This device will enhance mobility of your shelf stand and display racks. - The round corner design works seamlessly with 3, 4, and 5 mm curved rack stands. - Printing is achieved using a 0.3mm layer height with five layers on top and five layers on the bottom. - Three side layers provide sufficient support. - Filling requires at least 30% density. - Clean the wheelchair roller hole gently with an 11mm drill bit, avoiding penetration through the top surface. - Due to its snug fit, use a rubber hammer to secure it onto the shelf stand feet ends. Average printing time for a single adapter with optimal strength is approximately three hours.
