Mortising bit (8 mm) holder / attachement

prusaprinters

<p>This is a universal mortising bit holder. It is not attached to the drill machine, but can be held by hand or clamped to the drill/stand.<br>I used two 626 bearings (19 mm wide, 6 mm hole) and inserted them during printing (two times to set the printer to pause). I think these two bearings keep more stable the bit.<br>The clamp uses M3 screw (16 mm) and M3 nut (the nut fits very tight and I helped inserting it with soldering iron).<br>Of note, I have not yet tested drilling a mortise, but looking forward.</p><p>I used brim to help the tube stay in place on the bed, but you may try without any rafts.<br>Pause the printer in gcode twice to insert 626 bearing.</p><p>Post-printing:</p><p>Clean the print,<br>insert M3 nut and screw,<br>fit the clamp around the tube,<br>add additional 626 bearings on the top (one or more if needed, depending on length of the drill bit)<br>and finally add a small washer</p>
