Kossel 1515 pulley carriage upgrade

thingiverse

Your carriages are bending? There's a solution! These parts stop the bending by tightening the wheel from both sides. To do this, you will need an M3 screw and a Nylock nut. Instructions: Replace all the nuts with washers on the screws of the old carriage. You'll need three washers to replace one nut. Place the first washer onto the screw and then add another washer on top of it. This should be followed by another washer, which will complete the replacement process.
