Updated: Bracket bundle: 14 L-brackets and 16 corner braces (3mm and 6mm thick versions)

I made this bundle of brackets so you can print your own when needed. Both L-shaped brackets and corner braces, inside and outside versions.

All brackets are 3mm thick, with a 6mm thick version for extra strength when that is needed. 

The screw holes are all 5mm diameter, with 2mm countersink. 

L-brackets:

• 20x20 mm with countersink screw holes
• 20x40 mm with countersink screw holes
• 40x40 mm with countersink screw holes

• 20x20 mm with one countersink screw hole and one adjustable hole
• 20x40 mm with one countersink screw hole and one adjustable hole
• 20x40 mm with two countersink screw holes and one adjustable hole
• 40x40 mm with two countersink screw hole and one adjustable hole

Corner-braces:

• 30x30 mm outside corner brace for 2-sided corner
• 30x30 mm outside corner brace for 3-sided corner
• 40x40 mm outside corner brace for 2-sided corner
• 40x40 mm outside corner brace for 3-sided corner

• 30x30 mm inside corner brace for 2-sided corner
• 30x30 mm inside corner brace for 3-sided corner
• 40x40 mm inside corner brace for 2-sided corner
• 40x40 mm inside corner brace for 3-sided corner

The difference between inside and outside corner braces is seen in the chamfers on the screw holes, and a small fillet on the corner side of the bracket itself. 3d printed parts need a fillet in 90-degree corners for strength.

Print with lots of walls for maximum strength. 

I suggest you test-print a bracket before you put them to use, to see if they are strong enough for the intended job. They require very little filament. 

The 3mm L-brackets are nice and strong, the 6mm L-brackets are properly beefy!

UPDATE: 6mm version of the corner brackets have been uploaded.
