Next is to add some centering plots to my mould and reprint the mold in lower layer thickness than my first print. This will be long prints, but with the quality improvement and lower layer thickness it should be good enough to start with...

RC10Nick , what product do you use to prepare your moulds? Unmoulding agent only or do you do something else in addition?

Thanks
