Old Copper Secret Box

This is a remix from https://www.thingiverse.com/thing:3109214 \r\nMany thanks and respect to 3DPRINTINGWORLD for this great design.\r\n\r\nI haven't made many changes, but since many people have asked me how a 3D print can be reworked in color, I'd like to discuss it here.\r\nI love to transform things into old and used items, so the box should shine with a warm copper glow.\r\n\r\nTo the print itself:\r\nI printed all parts with vibrant orange PLA-filament, mostly in 0.2mm layer thickness. The bright orange filament offers the perfect contrast to the planned post-processing. \r\nSince the butterflies had a lot of overhangs, I printed the individual parts without them, and attached the butterflies after printing using strong adhesive. On both sides and on the back there is a butterfly in 70% size. On the lid I have placed 2 butterflies in 50% and one in 70% size. \r\nI provided the key with a few supports, which can be easily removed and sanded after printing.\r\n\r\nFor finishing:\r\nAt first all parts are carefully sanded with fine-grit sandpaper, it is not a matter of removing all unevenness, but of roughening the surface. As I varnish without primer, the paint would not adhere properly otherwise.\r\n\r\nFor the varnishing I use high-quality acrylic paints, namely "Vallejo Model Air" which I apply in this case with the brush and not with the airbrush. The colours I use are all included in the Set1 (6 basic colours) of Vallejo. \r\nFor the following copper finish I use Rub'nBuff wax-metal finish, colour "Spanish Copper".\r\n \r\nThe copper finish is best used on a contrasting base.\r\n\r\nI used the following mixing ratio: \r\n- 15 parts black\r\n- 7 parts yellow\r\n- 4 parts red\r\n\r\nI always change the mixing ratio a little to create contrast differences.\r\nVery good is also the same amount of olive green mixed with black.\r\n\r\nAfter all colours have dried, I start with the Wax Metal Finisher.\r\n\r\nThere are 2 good effects: \r\n\r\n1 - The wax finish is only applied to the edges and the excellent surfaces. This creates the effect as if the paint is worn out through use, and the bare copper comes out. This is best done with your finger, but it gives you the best feeling when polishing the edges. Don't worry, your fingers will simply be cleaned with soap again. It is always important to apply and polish only very small amounts with your finger.\r\n\r\n2 - The wax finish is applied over the entire surface. It is important that the primer shimmers through again and again. I do this with a stiff brush, where I shorten the bristles extra. The box shown here I have worked with this method.\r\n\r\nPrinting parameters:\r\n40% filling density\r\n0,2mm layer height\r\n3 vertical contours\r\n3 horizontal contour envelopes\r\n80mm/s Print speed\r\nSupport is not required.\r\n\r\nWith a successful print I would be very happy about a Like!\r\nGreetings Hardy
