5/8" Square Tubing End Cap

thingiverse

I'm crafting a custom shelf utilizing 5/8" square tubing; I've acquired both 3/4" and 1" end caps, yet lack the corresponding 5/8" size. I've engineered this design with the larger caps in mind. This solution features an end cap designed specifically for 5/8" square tubing. Initial testing was conducted using 16 gauge walls, although there's uncertainty regarding its effectiveness with 18 gauge material. Fortunately, it should accommodate 14 gauge tubing without issue. Please note that you'll need to rotate the object as depicted in the STL file in order to orient the cap atop the build plate correctly. This design is scaled for use with ABS plastic, which might result in a slightly oversized print if PLA material is utilized. A revised iteration (Rev) may actually work better when printing with PLA, whereas previous versions recommended ABS plastic exclusively (Rev A).
