Parametric L-Bracket (Angle, W D, H, Thickness)

Generate L-brackets for any use with this fully parametric OpenSCAD L-Bracket generator. This model lets you control every nearly part of the model: plate sizes, angles, hole patterns, braces, edge rounding, and inner gusset. With bracing and inner triangle i found these surprisingly strong even at 2 walls and 5% gyroid infill. 

Size holes correctly for heat-set inserts and you can bolt directly to the bracket (see photos) - used this to create a bracket to mount a 1u ac infinity fan to the bottom of a server rack.

Included 3mf has all brackets seen in photos + the AC-Infinity bracket.

Features:

• Independent plate control: Set width (X), depth (Y), height (Z), and plate thickness independently.
• Adjustable angle: Default 90°, but supports acute or obtuse angles.
• Hole system:
  • Shared width (X-axis) holes across both plates
  • Configurable grid patterns for horizontal and vertical plates
  • Optional countersinks (flat-head style, 45° taper
  • TODO: mimic plate system where lists of holes can be supplied for each plate 
• Edge rounding: Smooth edges with Minkowski-based fillets on either plates, braces or both.
• Bracing: Add left, right, or middle wedge ribs for structural rigidity.
• Inner-corner gusset: Optional triangle support in the inner corner that is automatically aware of holes - it won’t block them.
  • KNOWN ISSUE: size is finicky and needs to be fixed as with obtuse angles the size is .. less then idea
