If you are also considering purchasing the effector knob guards, etc., that we are selling at the same time, we can ship them together. Please let us know in the comment section before purchasing. ---------------------------------- Please read the following notes before purchasing. ⚠️Notes⚠️ 1. Although we have confirmed the installation and operation of this product with the zoom G5n, we have not confirmed the installation and operation with other zoom products. Please read the product specifications carefully before purchasing. 2. Due to the nature of 3D printing, there may be dimensional errors, variations in design, burrs, layer lines, stringing, and chips in the product. Caution⚠️ [There are differences in the outer diameter of the main switch parts themselves and the thickness of the coating, etc., so the product may be installed tightly or loosely. Please understand and acknowledge in advance that we will not be able to process cancellations, exchanges, or refunds in such cases.] 3. Do not apply excessive force to the product, as this may cause damage or injury. ---------------------------------- Product Name: [zoom11 Hat G3n] Product Description: Foot switch hat for zoom G3n, etc. The foot switch hats for G2XFOUR and G3X, which we are selling at the same time, could not switch the switch when trying to install them on the G3n (B3n) and G5n made by the same company because the bottom of the outer diameter of the switch hat interfered with the top surface of the main unit. Therefore, by making the overall height of this product thinner, it is now possible to switch the switch. Also, many of the zoom effector foot switches use 11mm outer diameter foot switches. Since the 10mm inner diameter foot switch hats made by MOOER, etc., cannot be used, we have created a 11mm inner diameter foot switch hat using a 3D printer. How to install: Press this product onto the foot switch. Packing contents: [zoom11 Hat 4-piece set] x 1 Product Specifications: Outer diameter: Approximately 25mm Inner diameter: Approximately 11mm (depth: Approximately 5.5mm) Overall height: Approximately 9.7mm Material: 3D printer filament (PLA+) Color: Silver
