Parametric drinks coaster. (Half_life, Portal, make_your_own)
prusaprinters
TLDR; I just want to print these coasters, which files are for me? _Coaster.stl files _Coaster_logo.stl files This multicolor print is designed to be printed on single color printers which support the M600 g-code command. (Most printers using the marlin firmware should be able to do this if they have it enabled. Tested on a Prusa i3 MK3S) I've added all the STLs I generated myself and all source material I used, except from the coaster with the Aperture Science innovators logo. The model for the logo was downloaded from Grabcad, and they their own taste of licensing. My legalese is basically non-existent so I decided to not redistribute that one. You can get the STL yourself though and follow the steps to generate one. Link: https://grabcad.com/library/aperture-science-innovators-logo How to use the openscad files: Converting an svg logo to stl for use with the coaster: Make sure you're using openscad version 2019_05 or later Put the Svg you want to use in the same folder as Svg_To_Stl_conversion.scad Open Svg_To_Stl_conversion.scad Change the filename to match the one you want to use Press preview and verify the logo looks good (Note: While most svg files I tried worked, I had a few where it would just generate a square. I have no idea what causes it or how to fix it. I just tried another svg file) Press render and check again Press export to STL Open the STL in PrusaSlicer (To have an easier time to center the object) Set the position to X = 0 and Y = 0 in the bottom right corner Export plate as STL Done. The export from PrusaSlicer is the one you want to use with the coaster. How to generate a coaster: Make sure that the logo STL is in the same folder as the file Parametric_Coaster.scad Open Parametric_Coaster.scad Adjust the parameters if you want Change Logo_stl_path to the filename of the STL you want to use as the logo Set Generate_part to 0 and preview, render and export the STL for the coaster Set Generate_part to 1 and preview, render and export the STL for the logo How to print with multiple colors on a single color printer: Instructions on how to generate gcode with required manual filament swap were made by joantabb over on the prusaprinters forum: https://forum.prusaprinters.org/forum/prusaslicer/manual-multicolor/#post-188236 The short version: Add an extruder to the printer settings. For custom gcode on tool change, set M600 In the print settings -> multiple extruders disable the wipe tower Select both the logo and the coaster stl files and drag them into the prusaslicer window Answer yes so that they're recognized as a multi-color model Slice your file as per normal At the start of the print it will already generate a tool swap, so just remove an re-insert the filament. When it reaches the logo, it will pause and ask you to swap filament. When the logo is done it will ask you again and finish up the rest of the print. I've also added 3MF files which you can open in PrusaSlicer. These include the models I used with the print settings I used. If you have a multi-material printer you can ignore all that and just print it like any multi-material print.
