So you have this nice, $800-1000 dollar Husky toolbox... and now suddenly the drawers no longer stay in place and decide to roll out randomly. What gives? Well, 2 things.
1) Either the body/legs or the retainer is broken on the mechanism
2) The drawer itself has a metal "hook" that it used to grab the retainer, and has finally chipped away enough of it that it will no longer "Pull" with the drawers actuation, causing it to no longer reset the retainer position and stay open
This design is not only meant to be a replacement, but also an improvement.
-The legs are thicker with more support structure and less of a angle
-The "tongue" is larger and sturdier, and sticks out a small bit farther too
-Some of the walls that meet the spring are thicker
-Noticed while the stock pieces have a tendency to crack/break on removal, my redesign only broke 1 leg after 5-6 removals in a row while the body and everything else broke on the stock ones.
YOU WILL NEED TO ENABLE SUPPORTS TO PRINT THIS***
All the normal settings should work, for this particular piece this is what I used:
100% infill, Gyroid
.1 layer height
Support enabled, Zig Zag, .05 support to print Z distance
Initial Build layer .2, at 15mm/s speed
Using latest version of Cura
-Remove the old mechanism, its going to get destroyed which is fine. You will need the springs.
-Assemble the new pieces, with the spring, and throw some lube on the spring and on the actual retainer itself so it slides onto the drawers hook easier
-Line up the part that has the alignment squares, and put either both the bottom legs or both the top legs in, and get that sides bottom alignment square nearly all the way in
-Once that is in, you can use a screw driver to apply pressure near the alignment squares on the leg to push it into place. Use common sense here please.
-The top two legs should now either have slid into place or be very close. The important part youre looking for, is that the legs DO NOT GO UNDER THE RAIL, they instead go behind it, putting pressure against the LIP of the rail and the lip of the leg. Make sure your alignment squares are both snugly pressed in (this is what keeps it from hitting the drawer) and then slightly bow the legs out into the orientation mentioned with a screw driver. Done.
Test it out a few times, it takes some work to get it perfect. I already fixed 3 drawers with it, and they are working flawless. This is the first piece I have ever designed in a 3D modeling software so sorry for any small issues, although there should be none.
*Update 4/15/2019: Made the main unit closer to oem looking, fixed a couple of geometry issues on the original model that was causing undue weakness on certain areas.
