Check the listing for details. Milwaukee PACKOUT integrated battery storage M12, M18 external/internal. Condition: New. Listed at 13.66 USD. Printed proper in PLA+, tough and durable. also be aware i have sold 850+ units of these but ebay has for reasons unknown reset the listing...AGAIN. anyway please shop in confidence. NOTE: "BOX3" options are designed to fit pack out box designated: MIL4932464080 commonly referred to as "box 3" please be aware there are two versions and my holder (and your batteries for that matter) will only fit in the version that has the aluminium rail corners. NOTE 2: HIGH OUTPUT version batteries are slightly wider and cannot be next to each other in the holders. standard output is fine. Please consult the pictures/variation of your selection for compatibility information. units that need mounting screws have them included. care not to over tighten them, you only need a little pressure for a good secure hold. The blowtorch holders come in long or short versions, some blowtorch gas bottles (~75 mm round) have a ridge in the middle as part of the forming process these bottles can only be stored in the short version. both versions have an allen cap head bolt at the back to adjust how tight the fit is, so you can get your preferred level of snug for your bottle. Note: some items are too large for my high quality printers (I have larger but lower quality printers) to produce in a single print, these items are carefully designed such that they can be securely bolted together (at greater expense and effort to myself), I spend a lot of time figuring out the best way to do this and the only downside will be a visible seam to some items where this occurs. As always, my stuff comes with the buy it right buy it once guarantee: something goes wrong; i'll sort ya out. Take a look at my other items for other snazzy organizers.
