Great corner supports
Made a custom Ender 5 type of 3d printer using these and helped me from drilling holes everywhere. Very sturdy design.

L shaped inside corner brackets break easily
I really like the 3-Way End Corner Bracket Connector. The L shaped inside corner brackets break easily if any force is applied to them. If you are using corner joint plates for the strength in your joint, then these will be great to hold you joint in position until you put the plates on.

Work well and are easy to use
I bought these connectors to build an enclosure using extrusion shapes. The connectors worked well and were very easy to use; they made the job a breeze.

Really nice assortment to start a project.
This has the basic components you need to start projects. Maybe not everything, but I was able to use all of the parts here with no wasted parts. Price seems fair for what you get. Quality is excellent.
