Tool to mark the middle of a board/lumber with a pencil (with magnet holder)

thingiverse

Just a slightly different look than the original. NOTE - this model includes 2 voids designed to hold a 3mm x 8mm magnet each. If you are printing with a prusa, using .2mm layer height, you should export the gcode, search for ;4.2 (the start of the 4.2mm high layer). Add the following code to have the prusa stop for you to insert the magnet(s): G1 X10.000 Y200.000 E0; parking position GET THE PRUSA TO STICK IT'S TONGUE OUT! (edited to revise Y coordinate) M1; user stop M105; return to current temp Then, click the button to start printing (if using the SD card) or, if using octoprint - click resume in the interface. There are 2 versions uploaded here, the normal one has the voids for the magnets. The version "Middle_of_lumber-No_Magets.stl" is solid without any voids.
