Brackets for 1010 (10mm) MakerBeam®

After making some plates, I still missed some kinds of brackets in my Makerbeam® set.

Included is a FreeCAD file with customizable beam size, hole size, fillet.

STLs generated with:

• target: 1010 aluminum extrusion, M3 screw holes
• unit size: 10mm
• thickness: 1.5mm
• hole diameter 3.6mm (slightly oversized from M3 to account for printer tolerance)
• fillet radius: 1.0mm

WARNING: This is a work in progress.

It's mostly working for me, but some of the models may need retouching, some are still missing, and some may not make much sense and may be removed.

When multiple options for a piece are possible, some "common sense" decisions have been made, which may or may not be the optimal for a given use.

Some parameter combinations may result in broken models.

Post-Printing

Final pieces have some give, but are sturdy enough that when put on opposite sides of a beam can stabilize it.

For additional rigidity, with the stock M3 screws, up to 3 pieces can be stacked.

Final hole size depends on printing precision; may require some deburring, or may work directly out of the printer.

How I Designed This

Design considerations

• Minimize size
• Maximize versatility
• Match stock plate thickness
• Where possible, align holes to grid
• Limit overhangs to 60º to avoid the need for supports (except holes)
• Discard designs that are too easy to break

Alternatives:

• Perpendicular borders: help with alignment
• Circular borders: more versatile, use less material
