This is a remix of an Irwin 5-piece countersink bit holder that is a great model. The only problems were the tab breaks and the smallest bit holder was not quite the right fit. This is my effort to fix those problems by adding a latch and adjusting the fit of the smallest bit holder. This is made to hold an Irwin model number 1877791 bit set. I printed this on a Bambu Lab X1C. I am by far new to 3d printing but, if you care, this was printed in PLA at a 0.12mm layer height and slim tree supports. I also added a brim to the latches due to their small size. This model is made to fit a M3x20mm socket head cap screw. I did tap one of the tabs to hold the bolt in place.
The author remixed this model.
Because the tab broke on the original design I changed to model to use a latch. I also adjusted the length of the smallest bit holder to fit better.
