Overview: 

These customizable 90 Degree Flat Corner Brackets are perfect for making a quick frame out of lumber! It's already hard enough to get furring strips that are straight, let alone a uniform size.  

I wasn't able to find any models that fit the 1x2 (nominal size) furring strips I had on hand. So instead of modifying someone else's design, I made my own that could be adjusted to fit any board I may have. 

Features: 

• Customize to fit your exact size of furring strips. This could be used for something as big as a 2x4, however I would suggest adding extra holes in your slicer to screw into the sides. 
• Sturdy design with recessed screw holes in the rear.
• Bracket is designed to take a lot of the bending load, since fastening corners on furring strips often leads to split lumber.

What can be customized?

Every callout on the diagram below can be customized. “Leg_Extralength” adds length to the length of the recess on the bracket, so increasing the value means the recess is longer (allowing extra screw holes / adding structural support). 

Print Settings: 

• No supports required!
• Use whatever filament you desire based on the use case and environment (Don't use PLA for hot climates or it could melt). 
• 0.2mm layer height or lower is ideal.
• Suggested to add extra wall loops & infill. The included print profile has 3 wall loops and 20% recilinear infill. 

Parametric Bracket System:

This is designed to work alongside my other parametric furring strip brackets (collection & additional models coming soon!).  

If you like this design, please consider dropping a like, comment, and/or a boost. I'd love to hear feedback and improve on this model.
