If you wish to buy them, they are available at my Etsy shop: https://www.etsy.com/uk/listing/899622154/personalised-kilner-jar-labels A customisable Kilner Jar label that clips to the lid of the Kilner Jar and makes knowing the contents much easier! Printing involves generating the 2 part model, combining in a text editor and printing. The models are printed on top of each other to form a single flat layer of two colours. Please see the related video on my Instructable https://www.instructables.com/3D-Printed-Kilner-Jar-Labels-Using-SCAD/ Create customised snap in place labels for Kilner jars. I was having issues working out what type of flour or sugar was in the jars, so designed and printed these clip on labels. Use OpenSCAD to generate the STL files. There are 4 parameters that should be changed for choice: 1. textSize - Size of the text to display 2. drawText - Used in conjunction to 'singleColour'. If singleColour is set to false, drawText set to true only draws the text and the circular band. If drawText is set to false, the rest of the lid is drawn. 3. singleColour - Used to create a single colour lid (if set to true) or a 2 step multi-colour lid (if set to false) 4. textLabel - The text to put on the lid. Once the lids have ben 'rendered', export each of them as a STL file Single colour design prints easily as normal. Multi-colour design requires some work with a text editor. Instructions for multi-colour: 1. Generate the 'drawText = true' and the 'drawText = false' for a given textLabel. This will produce 2 STL files. 2. Slice both of these files INDIVIDUALLY in your chosen slicer. I use PrusaSlicer. In PrusaSlicer, objects are automatically centred on the build place. This is why I create the ring on teh outside, so both objects are exactly the same size and they are exactly centred. Save the GCODE for each of the objects. 3. Load both GCODE files into a text editor. 4. A GCODE file will contain a lot of setup information, but in the PrusaSlicer GCODE there is a comment (about a page down) saying: ;AFTER_LAYER_CHANGE ;0.2 At the bottom of the file, there is a large section of comments detailing the PrusaSlicer configuration parameters, just above that is the 'clean up' section where the GCODE tells the printer to turn off the hot end (M104), turn off the bed (M140), and turn off the fan (M107). in my GCODE it looks like: M107 ; Filament-specific end gcode G4 ; wait M221 S100 M104 S0 ; turn off temperature M140 S0 ; turn off heatbed M107 ; turn off fan G1 Z38.8 ; Move print head up G1 X0 Y200 F3000 ; home X axis M84 ; disable motors M73 P100 R0 M73 Q100 S0 5. Copy ALL of the text from between the start (after the comment) and just before the M107 from the 'non-text GCODE file'. 6. In the 'text GCODE file', scroll down to the bottom of the file, and find the M107 as described just above. 7. On the line BEFORE the M107, add a couple of blank lines, then add a M600. The M600 tells the printer to ask for a change of filament. 8. Paste all of this copied code from the non-text GCODE file (step 5) into the 'text GCODE file', after the newly inserted M600. 9. Save the file. For example: : : G1 Z1.200 F10800.000 M600 ;AFTER_LAYER_CHANGE ;0.2 G1 X77.079 Y65.365 : : By doing this, the printer will print the first 3 layers of the print (0.6mm) in one colour, request a colour change (M600), and then print the second colour around the first colour. TIP: When starting to print the second colour, turn the speed right down to about 70%. This slows the printing down, and reduces any issues of the first print being knocked and removed from the build plate. Once the second colour completely surrounds the first colour on the fjirst layer, you can turn it back up to 100%.
