Creality CR-10 Laser/Plotter/Dremel flex shaft adapter

thingiverse

Quick mounting solution for CR-10 laser, adapted to make household pens/markers easy to use as plotters and allow flexible Dremel adapter usage as a light-duty engraver/etcher. For Laser: I wanted to mount the laser in a way that makes it easy to add or remove without affecting the stock hotend mount. This design uses four 5 mm M3 bolts threaded into the laser housing to keep it in place, two 10 mm M3 screws to hold the mount to the x-carriage, and a 1/4-20 bolt cut to 15 mm long to attach the laser to the mount. I made a bolt adapter and cap to help make this a tool-less mount. This mount positions the laser approximately 25 mm higher than the nozzle, allowing enough room to adjust focus while etching. For Plotter: A recent discussion on using a 3D printer as a plotter led me to realize that my laser mount can be adapted to hold a pen or marker. All it needs is a few more holes for a flexible mounting system, with a pressure plate to hold the pen, four M3-M4 bolts and washers, and a backplate (or small washers). I printed my pressure plate with TPU, but you can use other filaments and a layer of felt, rubber, cork, or another interface for easy adjustment. For plotting, simply create a single layer print (or use your slicer to only print the first layer) and enable z-hop during retraction, setting a large value to allow the pen/marker to clear paper. Depending on pen/marker size, you may want to set x-offset around 40 mm and y offset around 20 mm to account for the pen being offset left and in front of the nozzle. For Dremel, use the longer mount and pressure plate to hold the Dremel flexible shaft adapter in place. 10-14-2019: I added spacers that can be clipped onto the x-gantry above the z-axis limit switch to keep the nozzle from hitting the bed when using laser, pen, or Dremel attachments.
