After multiple attempts at creating a design that does not produce UNDERCUTS during CNC cutting, below is another attempt at making a simple mold. However, due to material restraints (depth size limited to 1.5″ of foam), and to prevent another undercut, I had to divide the bracelet in the middle, into two parts. I didn’t quite develop a detail that would incorporate the seam line (for example a ribbed detail that would hide the seam).
At first I added undulating ‘bumps’ on the top surface of the bracelet, but quickly realized that it would also create undercuts. Instead, I created a simple, single wave surface.
2″ thick foam
Shopbot
1/4″ dia drill bit for both roughing and finishing pass
However, I didn’t have enough Oomoo left after the wall tile mold pour to complete this mold. I will test this out later!
