europond two anti-warp mould

thingiverse

To stop warping I place pound coins on the heat table away from the raft footprint so that they heat up. As the build exceeds the height of the raft plus the height of a pound coin I simply place a pound coin edge onto the raft. As the height increases I put more pound coins on and the weight seems to stop the raft warping. The bigger the model the more the coins needed. To get the height for insertion right I have made some moulds that can be added close to the raft so that the rims overlap creating a wider raft where the weight of the coins act as a levered weight and help stop warping. As the model climbs, when the next height wall starts to show, slip another pound coin in. I'm sure it will work for Euros in a gesture of goodwill to my fellow European citizens. I have put a one, two and three height mould for coin application for download, europound one, europound two and europound three for one, two and three coins respectively. Simply place them where their rafts will overlap with the main model. You might want to orientate them for easy access.
