Hello! Hope everybody is doing well.   I want to compress the planter which is in the attached drawings. Before quarantine, I got a big pizza oven and the idea is the build an external press machine, put the plastic flakes in the mold, melt them and then press it on the compression machine.   I need some advice about mold building: - Which should be the thickness of the metal sheets to use? - Should the mold need to be structured? - Do the parts need to be CNC cut? - and any further detail that could help me to make a good mold.   Thanks in advance!
