I was a bit worried about acrylic working. maybe some mold release agent or power release? yeah 1/8" acrylic im thinking would have to be pretty hot to form. i dont think i have heard of extruded sheets i know its an option on rod tubes and other thicker acrylic products.
Might have to try the polycarbonate but unsure how it would react and then it would lose some of its chemical resistence and is more prone to crackling. the mini playfield is polcarbonate and they broke with less ball force than the ramp would endure.
Hmm has anyone seen any ABS plastic sheets in other transparent colors other than clear?
As far as i have have ever found blue acrylic comes in 1/8"-1/4" thicknesses it would be nice if it could be found in 1/16" thickness for this project but then it might be too brittle
I would suspect the acrylic shrank when it cooled down and contracted around the mold but the blue acrylic should be very close to the same color as the upper mini PF.
