00:00Hey everyone! If you're building a 3D printer, a CNC machine, or just a custom workbench,
00:06you already know that your frame is only as rigid as the hardware holding it together.
00:11I've spent hours digging through user feedback and specs to find the absolute best deals on
00:15the top 5 aluminum profile connectors for 2020 extrusions that you can pick up right now.
00:21Starting off at number 1, we have this 8-pack of L-Type angle corner brackets.
00:26What I really love about these is their compact, internal design that keeps your joints solid
00:30without getting in the way of moving carriages, toolheads, or side panels. Getting 8 of these
00:36for just $5.71 makes it an insane value, backed up by nearly 5,000 orders and a great 4
00:42.8-star rating.
00:44If you're putting together a basic square frame on a budget and want a clean look,
00:48this pack will stretch your dollar the furthest. Next up is a 4-pack of solid aluminum triangle
00:53block connectors coming in at $6.38. The standout feature here is pure corner rigidity,
01:00the solid triangular wedge provides far more surface contact against the extrusion faces than a skinny
01:05bracket, which drastically cuts down on frame wobble and racking. Sitting at a stellar 4.9 rating across
01:12thousands of buyers, the machining tolerances are noticeably consistent. They're well worth grabbing if
01:18you're building something subject to heavy vibrations, like a direct drive 3D printer or a small laser engraver.
01:24If you only need a quick reinforcement or a small upgrade, check out this 2-pack of V-slot triangle
01:29angle blocks priced at just $3.57. These boast a flawless 5-star rating, and what makes them
01:36special is how cleanly they Nestle into both V-slot and standard T-slot channels for an ultra-flush,
01:41secure connection. At less than $4 for a pair, it's an easy, low-risk add-on to toss into your
01:47cart if you
01:47just need to shore up a couple of critical stress points without buying a massive bulk kit.
01:52Number 4 takes things up a notch with this heavy-duty 20S extruded right-angle corner bracket kit that
01:57includes the matching mounting screws for $13.31. The best part is pure convenience, you won't have
02:04to waste time digging through hardware drawers trying to find the exact right length M5 bolts and T-nuts,
02:09because it's a complete set ready to bolt on right out of the package. It holds a perfect 5-star
02:14rating,
02:15and while the price is a bit higher, the thick, cast structural strength and included hardware make
02:20it totally worth it for serious load-bearing projects. Rounding out the list at number 5,
02:25we've got this 4-piece set of sleek black L-shaped corner brackets for just $5.64.
02:31The standout feature here is definitely the clean anodized black finish, which blends seamlessly if
02:36you're rocking black aluminum extrusions for a modern, stealthy aesthetic. Rated at 4.8 stars with over
02:434,000 units sold, these give you plenty of clamping force on CNC and printer frames while keeping your
02:48entire build looking unified and professional rather than cobbled together with bare metal.
