Long eccentric spacer for Tronxy X5S

thingiverse

The main drawback of X5S design is the absence of v-slot roller adjustment. It's crucial that carriages run smoothly, with no friction and no residue. Typical eccentric nuts are 6mm high, but Tronxy X5S use 8.5 mm long spacers. Here are two solutions: 1) The Easier Option: Print One The neck is a bit weak, so the spacer shouldn't be turned under stress. 2) The More Involved Option: Use More Tools You'll need a 6mm eccentric spacer and a tuned M5 nut. The M5 nut height is 3.9mm, so it needs to be cut down by 1.4mm using a grinder. By placing two M5 nuts on top of the bolt and grinding them down to 6.6mm, you'll leave the top nut with a thickness of 2.5mm. The X5S roller axle holes are 5mm in diameter, but eccentric spacers require a 7.1mm hole. Acrylic cracks easily, so it's essential to drill carefully. The best approach is to use a pillar drill, but this thing: https://www.thingiverse.com/thing:3041641 worked for me with 1/2 mm steps. To trim the final 0.1mm, I used a 5mm drill bit covered with sandpaper (120), allowing the eccentric nut to fit in without any force. Place the M5 shim plates under the axle bolt heads.
