Customizable Picatinny Cylinder Holder for 0.835" / 21.20mm Pic Rail **One M4x30 screw is required to secure the holder on the rail.** ### Variables * Holder Type: Selecting "Closed Clamp" mode ensures the cylinder cannot be removed without loosening the screw. * Cylinder Diameter: Enter about 1.0mm less for a tighter fit in "Open Clamp" mode. * Clamp Thickness: A recommended minimum of 3.2mm is required for "Open Clamp" mode, with an absolute minimum of 0.7mm. * Offset to Picatinny Rail: The minimum distance from the cylinder to the Picatinny rail is 3.3mm. * Holder Length: The minimum holder length is 14.75mm, due to the distance between two grooves. * Locking Screw Alignment (M4x30): Choose "In the Middle" or "At the Edges." If "At the Edges" is selected, the holder's bottom will be flush with the recoil groove side. If the holder length is 24.75mm or greater (in 10mm increments), a second locking screw hole will be added. * The default variable values and available STL files are optimized for the Anker PowerCore 5000 Powerbank. ### Contact Me Visit my Instagram page at [www.instagram.com/ar3amas](https://www.instagram.com/ar3amas).
