Here's how I made a mold for 32-times normal size snap-together
bricks. [Materials and tools] [Six Boards] [Pipe Segments]
[Circles] [Holes and Disks] [Logo] [More Disks] [Bottom] [Top]
[Alignment Pegs] [CAUTION] [Bungees] [Disks Again] [Foam] [Cost]
[Mold Release] [Assemble] [Pour] [Oops Too Much] [Paint]
[Results] The basic form of the mold is a rectangular box. The
six sides measure as follows: You can cut these pieces out of
four 24x48 sheets. Make the measurements and cuts as exact as
you can, otherwise the finished bricks may not fit with each
other in all orientations. Use the Sharpie to write "INSIDE" and
"OUTSIDE" on opposite sides of each board so you don't get
confused later. Next you need to cut the pipe into sixteen 2"
lengths. Start by using the tape measure and Sharpie to put
marks on the pipe every 2". Wrap the sheet of newspaper snugly
around the pipe so that its ends line up exactly, and secure it
with masking tape. This gives you a straight edge exactly
perpendicular to the pipe. Line it up
