prusaprinters

Ideal for rapid iteration and prototyping work. This unit provides torque-limiting via the marker's cap to avoid overtightening. Have too many ¼" hex bits but no driver in sight?  Or, you're midway between a piece and need a marker?  Both your needs have been answered at once.Instructions - No supports or post-processing needed.  Print vertically with hex side down. Simply press fit the circular hole of the attachment into the grey end of the marker.  Attach your ¼" hex bit of choice into the hex hole and then carefully provide force to ensure the bit and attachment grab. See Tips Section below if you need help.   You're ready to go! Benefits -Ergonomic multi-function toolingFast print with minimal plastic usage, upcycles existing material.Torque-limiting design, avoids stripping/over-tighteningUsage - Torque-limiting - One hand guides the attachment, the other hand holds the marker's cap.  Twist the marker's cap to drive the shaft.  The marker's cap will spin once the torque-limit is reached.Printing / Tips - I printed using standard PLA, at 0.2mm layer height and 20% infill, heated bed at 60c, which gave a secure tight fit for me.  I didn't use a brim or any supports. You can adjust your slicing parameters based on your printer settings to get a good fit.Hole too tight?  You can heat up the bit and then press-fit it in.  A mallet or hard surface could be useful to gently tap the bit in.  It doesn't have to be overly tight to work. Be careful and use appropriate safety measures if necessary.Want more grip?  You can slice it using the “Fuzzy Skin, Outside Only” feature to add texture on the outside, which you can vary.Version 1.0Some say the pen is mightier than the sword.  Perhaps the pen combined with a hex bit attachment with torque-limiting is mightier than the sword.  Enjoy and happy printing
