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.

Supports:

Resolution:

Infill:

100

Filament: SUNLU PETG White

Notes:

Printed in 1.5mm thickness PETG.

Set number of walls to 100 for a solid print.

Speed: 150mm/s, same for wall speed.

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.
