About this part

HUGE PROPS to WillsWorld for the original design. I just made a few easy mods to adapt this part for the newer shifters with reverse lockout. UPDATE: The model has been printed & test fit. Like a freakin' glove. #caliperlove Inserting the letters requires a bit of finesse & just enough brute force not to break the R and X apart- just be patient & make sure to clear any wisps/stringing in the knob & the letters to make it easier. UPDATE 2: As of January, 2019, this shift knob printed in PLA has been in my car in the Florida sun for well over 2 years. I do have 20% window tint all around (dark as legal in FL), but it gets plenty hot in my car & there was been no warping or softening of the plastic. Frankly, I am shocked. I figured I was going to have to re-print this in ABS or ASA by now. I did make this with 10 perimeters and 50% infill. I was still learning 3DP at the time, and way overcompensated, but it seems to have worked. Original text: I recently purchased a brand new, shiny 2017 WRX. Months back, I had seen Joel Telling, the 3D Printing Nerd, print & install this shifter in his 2006 WRX, and I decided that I wanted to try it myself, just for something unique. After failing to source the necessary hardware locally, I ordered on Amazon and then went to review the files before printing. And I noticed something was a little off. The original design was not intended for vehicles with the reverse lockout feature- the one where you have to pull up on a ring under the shift knob to access Reverse. In its original form, this shift knob would have essentially disable Reverse, because there needs to be a recess for the plastic bushing above the ring to pull up into. So I went outside & took some caliper measurements of the shifter setup in my 2017 WRX (Same generation as 2015+), and apparently, the STi had reverse lockout with the same dimensions even earlier. If you have a pre-2015 STi, it's on you to verify dimensions, etc. I then imported the files into Tinkercad and made the needed modifications. The visible mods are all on the bottom half of the knob. The shaft that extends below the sphere is wider & a tad longer to accommodate the lockout bushing. But the top half also changed, because the opening for the shaft of the shifter was too deep, and would allow you to screw he entire contraption down so low as to possibly block your reverse lockout mechanism, again killing Reverse. So I added a few mm of material to shorten the hole so that if you screw the assembled unit all the way down, it should bottom out just as the top of the lockout busing reaches the bottom of the shifter, leaving it free to travel into the recess designed for it. (Just like stock) Also added a small indent on the top piece for a Nylock nut to fit. (Many Nylock nuts have a ridge on top) I did NOT make any changes to the WRX lettering. I will simply include those files here. Hardware required: (1) m12 x 1.25 thread pitch Nylock nut.* (6) m3 x 20mm hex bolts (6) m3 x.5mm Nylo
