Depth gauge with scale in millimiters and a range of 20 millimiters, useful for router table depth of cut adjustments. This is a multimaterial model. I don't have a multi material printer but learned that you can create a multi material print pretty easily without special hardware (as long as the multi material part does not span over to may layers - otherwise it gets a pita). By multi material I don't mean switching filament at certain layers (which would not have worked in my case because I wanted the top and bottom layers to be on the print surface) but a true multi color print (as seen in the pictures). Here is a short instruction of how it works: I used Prusa Slicer for this but I guess it would work with the original Slic3r in a similar way ## Setting up Prusa Slicer - In Prusa Slicer go to the "Printer Settings" tab. - In the "Printer Settings" tab go to "General" settings. Under "Capabilities" increase the number of extruders to the number of colors you want to print. - For each extruder you will get an entry on the settings list on the left ("Extruder1", "Extruder2", "Extruder3", ...). - I would recommend to change the "Extruder Color" under "Preview" in the extruder settings for each extruder. This is not important but it will give you a better preview of the result making life a bit easier. - In the "Custom G-code" settings add "M600" to the "Tool change G-code" (M600 is the G-code command for a manual filament change). ## Setting up you print - The versions of the case that are intended for multi color printing have each color in a separate STL file. - On the "Plater" tab click the "Add" button and select the STL files for all colors at once ("at once" is important here). - When more than one extruder is configured and you add more than one file at once Prusa Slicer will ask you "Multiple objects were loaded for a multi-material printer. Instead of considering them as multiple objects, should I consider these files to represent a single object having multiple parts?". Answer "yes" to this. - Check the preview to make sure the colors are what you want. If the colors are not correct you can change them by assigning another extruder in the STL file list on the right (second column). - Hit "Slice now" an transfer the G-code to your printer. ## Printing Whenever your printer reaches the M600 command it will pause outside the print area and prompt you to switch filament (supposedly your printer supports the M600 G-code command). ## Some Tips - The order in which filaments are changed is not consistent. I got around this problem by adding the M600 command to the custom Tool change G-code setting as follows "M600 ; Switch to Extruder [next_extruder]". "[next_extruder]" is a placeholder that will be replaced during slicing. I then exported and opened the G-code file in a text editor and searched for the M600 command. I then created a checklist for each filament change to keep track of which filament has to be inserted next. Please keep in mind that extruder numbers in the G-code file are zero based. This means that extruder 0 in the G-code file is actually "Extruder1" in the Prusa Slicer UI. - When using the Original Prusa i3 MK3 the printer will extrude quite a bit of filament right after you confirm completion of the filament change to build up nozzle pressure. To avoid this extruded filament to be be dragged over to your print and make a mess don't remove the filament that is extruded during the filament change, so it will be easier to grab the whole thing. Before confirming completion of the filament change get ready to pull the filament waste away when the print head starts moving. This all probably sounds more complicated then it is. Once you understood how it works it's actually pretty straight forward.
