Ammo Box Mounting System v2


The Ammo Box Mounting System provides a quick and easy way to secure a Meanwell LRS 350 power supply along with virtually all of our controller mounts into the popular Harbor Freight Ammo Boxes to make a simple electronics enclosure. Designs are available for both the 30 caliber and 50 caliber ammo boxes and while they are different, they both work in similar fashions. The 30 caliber version consists of a lower insert and an upper mount and the power supply simply fits on its side and is held in place by the mount profile when the lid is closed. The 50 caliber version has a lower mount and two side mounts that can hold up to two Meanwell LRS 350 power supplies with the use of the included power supply standoffs. The power supplies in the 50 caliber version sit flat and are staggered for easy access to both sets of terminals. The mounting system works with all of our Meanwell LRS 350 mounts (sold separately), so you can mount any of the accessories such as distro boards, receiver boards, Raspberry pi’s and even a full F16 or Genius controller. While you can fit a full size controller or 16 port expansion board on the smaller 30 caliber boxes, generally speaking those should be limited to no more than two 4 port receiver sized boards and use the 50 caliber boxes for the larger builds. Colors may vary, typically they are white or black. If you have a specific color request for white or black please include a note indicating your preference with your order, but keep in mind that it may increase processing time for in-stock items. Includes 3D printed parts only. See below for a video showing how the Ammo Box Mounting System works.

3D printing parts is a slow process and we have a whole print farm running 24/7 to fulfill orders and build stock of the more popular items. If you order a product on backorder we will move it directly to the print queue where it will be printed as soon as possible. While normal processing times for most orders with backordered items is less than a week, it can fluctuate from time to time around 1-2 weeks. Very large orders can also experience longer than normal processing times as well. If processing times are expected to be longer than two weeks before shipping, there will be a banner at the top of the website indicating the expected wait times. Additionally very large orders could have longer delays due to the vast number of printer hours required for production of the parts. We will contact you and let you know the expected production time if it were to exceed the estimated timeline for very large orders. See the FAQ page for more info.

All of our 3D printed parts use PETG filament which provides good flexibility and resistance to UV exposure when used seasonally.
