<p>I've been hunting for a y-axis tensioner that looks like it would be stock, but haven't found anything not insanely over-engineered.</p><p>Like always, I finally landed on one I liked enough to remix. This time, it's from Thingiverse: <a href="https://www.thingiverse.com/thing:2995737">https://www.thingiverse.com/thing:2995737</a></p><ul><li>You'll need a 12-14mm screw to replace one of those holding the base to the front panel.</li><li>For the screws from the idler holder to the base, use 18-20mm.&nbsp;</li><li>To hold the idler in, you'll need a nylon lock nut and another 18-20mm screw.</li><li>And of course, you'll need a 16 tooth idler.</li></ul><p>Print the MK3 belt holder I attached. I used PETG and 30% gyroid infill with 3 perimeters and 1mm top and bottom, but whatever feels strong to you is just fine.</p><p>I just started printing with this and will update if I find any issues.</p>
