Festool 577808 SYS3 S 76 Mini Systainer is a compact modular storage case built for organizing and transporting small parts, accessories, and hand-held tools. This is a storage case designed for organized small-parts storage and transport. Model Number 577808. If you keep fasteners, electrical connectors, layout hardware, or specialty accessories bouncing around loose in a bag or van drawer, this little Systainer fixes that problem with a clean, repeatable setup.

The big win here is not just that it stores parts, but that it stores them in a way that stays organized. Festool includes four short partitions and one long partition, so you can break the interior into sections that actually match what you carry. That matters when you want screws in one spot, anchors in another, and a few install tools in their own compartment instead of all piled together. The inner dimensions of 10.15 in x 6.45 in x 2.63 in give you useful room for hardware and accessories without turning this into a bulky box.

The outer size of 10.43 in x 6.73 in x 2.79 in is what makes this Mini Systainer practical. It is compact enough to live on a shelf, in a service vehicle, or on a workbench without eating up space. Weight is only 0.88 lbs, so even when you load it with common jobsite hardware, it is still easy to grab and move. The built-in handle helps with quick carry, and the low-profile form factor makes it a smart fit anywhere you need small-item storage that stays neat.

Where this case separates itself from a generic organizer is system integration. The Festool 577808 SYS3 S 76 Mini Systainer is designed to work with the Systainer³ Rack, where up to six Systainer³ S 76 units can be stored like drawers. That gives you a cleaner way to build out a modular parts station in the shop or van. It also fits into Systainer Systems vehicle equipment when used with the rack, so the same organizer you use at the bench can move with you to the job.

Festool also built in some flexibility on the compatibility side. This unit can be combined with others of the same type and with SYS-MINI 1 TL. That is useful if you want a dedicated case for drill bits, one for connectors, one for specialty hardware, and another for small repair items. At the same time, Festool is clear about what it does not connect to: it cannot be connected to SYS 1-5, SORTAINER, or SYS MINI classic. That is worth knowing up front if you already run older Systainer setups and need a direct latch-on match.

From a load standpoint, this compact case is stronger than its size suggests. It carries up to 11.02 lbs on its own, supports 33.06 lbs when connected, and has a lid load rating of 220.4 lbs. For a small organizer, those are useful real-world numbers because they tell you it is built for jobsite stacking and everyday handling, not just light-duty drawer duty in a hobby room.

Who should buy this? Anyone who loses time dealing with loose small parts. Electricians can separate connectors and terminals. HVAC techs can keep service parts together. Carpenters can sort specialty screws, biscuits, or layout accessories. Remodelers and punch-list crews can build task-specific kits that stay packed and ready. Serious DIY users will also appreciate it, especially if they are tired of cheap plastic organizers with random compartments that never fit what they actually use.

If you already work in the Festool storage ecosystem, this is an easy add-on. If you do not, it still makes sense as a compact standalone organizer with better structure than most bargain boxes. The point of the Festool 577808 SYS3 S 76 Mini Systainer is simple: keep the small stuff visible, separated, protected, and ready to move.
