2020 Aluminum Extrusion Connector Bracket Set Included 8PCS Joint Plates,40Pcs M5 T-Slot Nuts and 40Pcs M5x8mm Hex Socket Cap Screw for 2020 Series Aluminum Profile 3D Printer Frame

Great, Just what I needed to reinforce my SIM RIG.

These are painted, not anodized. Back they go. Thanks for wasting my time.

I think the kit is great. To do the whole printer however you need two sets I didn't realize or think about that. I think the quality is fantastic it came with plenty of screws and t nuts. For those who complain that it's missing screws and t-nuts, if you tap the holes on the ends of the extrusions, you don't use t-nuts. I ended up with extras in the end. I haven't had any issues as of yet, with the t-nuts breaking. I didn't go crazy over tightening them. I bought the kit twice not because I thought it was great but because I didn't realize I needed more pieces however I believe the kit turned out to be great and I'm glad I purchased it. I admit there is definitely a flat side of these brackets. I put the flat side towards the frame. The front edges are slightly rounded more so so I let them face outwards. No sharp edges.

A absolute disappointment. The slide nuts don't meet spec. This is a time sensitive project so I will have to hand file every one to make it fit.

Exactly as described, with accurate quantities of parts
