Target PillowFort Letter Board Block

thingiverse

Measured the default block lettering for my daughter's PillowFort letterboard from Target and put into tinkercad design at https://www.tinkercad.com/things/9wLuN8UXDaM-targetletterboard/ I included an example of a dog that I printed and then glued to the included backer block. You can go make a copy of the tinkercad project and create more decorations or more letters matching their dimensions as desired. For the effect shown in the picture with the dog I utilized the M600 command in my marlin firmware to perform a filament swap starting with pink silk PLA and then swapping over to black PLA for the final layers. First I sliced in Cura and determined which layer transitioned from the silhouette outline to actually start drawing the dog details and noted it (Layer 8 in my case). Then after saving the gcode to file I opened the gcode in text editor and searched for "Layer:8" and inserted an M600 into the code. I print via pronterface so I was able to watch the print and once it got to the M600 line the printer started unloading the existing pink silk PLA filament and let me load in the black PLA. I did a few purges and then gave the extruder nozzle a quick wipe and hit continue. The silk PLA prints at 200-210C while my black PLA prints at 180C. A few seconds at 200C wasn't doing any harm so I just set the extruder temperature down to 185C once the print had resumed in pronterface. If you're going from a lower temperature to much higher (like 180 PLA to 235 PETG) you should use the resume temperature R[n] argument to M600 eg: M600 R235
