Letter & Symbol building blocks

Letter and Symbol bricks which are compatible with Lego blocks.

They can all be printed without supports.

I recommend printing them directly onto a smooth print bed like glass, without using a raft (In my test prints, the letter “A” was printed with a raft, while the “B” was printed directly on a glass bed and it has a much better fit).

My setting in Cura was "Initial Layer Horizontal Expansion = -0.1mm

I have included a full set of upper & lower case alphabetic characters, plus digits and a fairly large set of symbols (an expanded set of symbols is only included in the shorter brick set).

The shorter set includes an expanded number of additional symbols for arrows, squares, clubs, hearts, etc.
