Adjustable feet & endcap for 20x20x2 mm square tube

pinshape

Adjustable feet for a 20x20x2 mm square tube are a must-have for getting things level on the floor. I've also included end caps without threads, which can be used for protection or just to add some style. I recently used these adjustable feet on a shoe rack made from metal tubing with great success. Print Settings: Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: 0.15 Infill: 20-80% I printed the adjustable feet in PLA with a resolution of 0.15, three perimeters, and 25% infill, which gave excellent results. If you find them too weak for your needs, try increasing the infill and perimeters to get the desired strength. The end caps without screws were printed in grey PLA at the same resolution but with two perimeters and 10 percent infill.
