KSP Jebediah postcard

Once I needed to send KSP postcard with real, offline post, but I couldn't find anything. So I made it myself.I printed it with PETG, and my friend (fond of KSP) used the card as a coaster for his tea mug.You can use a permanent marker to write an address at the white back side. There are 0.4 and 0.2 nozzle versions.v0.4 is 103% sized (103x154,5x1,16mm size), and the lines for the address and postmark are relief without any color. I tried to make them colored, but 0.4 nozzle creates dirt on the surface, printing thin lines with PETG.v0.2 is 100x150x1,36mm size, lines for the address are colored, some white details are added to the Jool's surface.
