Anycubic Kossel Linear Plus Carriage Tensioner Variant

thingiverse

First revision, will probably remove countersunk screws again & reduce the diameter for the inserts to 3.9 or 4mm (if I ever do another one).Based on previous work from Old-Steve and pfjason. Thank you for making my old-ish printer better!My modifications:Widened the 4 non-carriage screw holes to 4.1mm for use with threaded M3 inserts (and weak loctite). Depth is 6.1mm, so fits both the shallow (untested) and long variants.this replaces the endstop screw with an M3 (use whatever you please)Carriage screw holes changed to counter sunk M3x12I realized my original Anycubic carriages had some play, likely caused by the screws being a little bit too long. Due to this I can wiggle the carriage a little bit, which of course translates into effector motion. This is likely not relevant for slow printing, but I want to make sure it doesn't interfere with fast printing/accelerations or when using a piezo probe.I sticked with the 42mm width to retain the original geometry, and because I'm about to replace the rods with carbon and use mpjet ball joints with integrated spacers (as per https://www.thingiverse.com/thing:4396638).This first revision uses countersunk screws because that's what I had around & I hoped they'd help center the carriage. However, the smaller drive with limited depth is annoying.If I disassemble the motion system again, I might change that back to the normal screws (for now they're holding pretty well, so I might live with it - remaining wiggle seems to be from the rail itself).I did not change the slider, but included the STL for convenience.
