This model is used to store just about anything while also being aesthetically pleasing. The jar has a diameter of 95mm and is available in both short (80mm height) and tall (95mm height) sizes. The default sphere jar top handle is included in this model package. All Jar Top Handles are attached using one (1) M3x16 bolt (M3x12 is also acceptable). These can be purchased inexpensively at any hardware store or Amazon. The bolt passes through the hole in the center of the Jar Top and screws into the hole in the bottom of each Jar Top Handle. It may take a couple attempts at first – the fit between the M3 bolt diameter and the hole in the Jar Top Handle is tight to ensure the handle stays secured. Multiple Jar Top Handle versions are available for the Decorative Jar in the Rich 3D Designs store. An additional document will be included in the .zip file that gives more information on best settings when printing this model and any extras tips.
