I love sheet metal. And I love @FreeCAD

A technical drawing of a sheet metal part.  It is a bracked for mounting an RFID reader.

The flattened view is dimensioned for easily transferring the pattern onto the metal.  Bend lines are also marked so all the bends will later line up precisely.  On the right side, two 3D-views of the final part are shown.  One of these views includes the RFID reader that this bracket is supposed to hold. A picture of the final part with the RFID reader already attached.

@rahix @FreeCAD I totally agree, funnily enough I just dug out this folded metal robot rover I made years back to show someone, all done in sheet metal wb and CAM workbench, I CNC'd the aluminium on a small router I have and folded in my shed. Amazing these tools are available!

My hand holding a small (circa 20cm square) tracked robot rover. It has an aluminium body shell cut and folded and bolted together. Looks slightly mandolorian!

Added a little protection roof :)

A picture of an RFID reader mounted to a wooden beam. There is a roof over the reader to protect it from water leaking from above. The roof was bent from sheet metal and was assembled using blind rivets.

@rahix that looks excellent. Which tooling did you use for the bends?

@cccpresser A small segmented sheet metal brake (box and pan brake). It's been an absolute game changer and actually not too expensive!

@rahix can you please share the product name or link?
This sounds like I need to purchase it :)

@cccpresser @rahix would also be interested

And here's the absolute mess of a drawing I made to quickly transfer the pattern to the sheet metal...

A technical drawing showing the unfolded sheet metal template.  A lot of chaotic dimensions are shown, barely enough to transfer the pattern to the metal.  Two 3d-views show the finished shape.

@rahix what tools are you using to do these bends? The ones I have learned to use would have troubles with these geometries

@jakob small finger brake/box and pan brake. works pretty well, but you have to put a lot of thought into the design to ensure all bends are possible in the order you need to do them. can share more if you are interested :)
