Hypercube Evolution (NO brass inserts Version)8mm X-carriage

thingiverse

Making some changes to the X carriage, swapping out brass inserts for 3mm nuts, which proved to be a game-changer after discovering they were too close to the side wall and causing bearing misalignment. This tweak allowed me to install bearings before inserting the new nuts, ensuring perfect alignment. If you like this modification, you might also appreciate the YX carriages no brass inserts version: https://www.thingiverse.com/thing:2469902 Revision 1 and 2 have been semi-tested. Here's a breakdown: Rev1 removes brass inserts from the sides, making room for M3 lock nuts. Rev2 takes it a step further by removing all brass inserts. The remaining holes use regular M3 nuts, not lock nuts. A radius has been added to the edge to make bearing insertion easier. I've printed Rev 2 and tested one side with screws and nuts; it seems to work as expected. However, I'd like to tweak a few things: I'll round the screw slots instead of leaving them square, which should add extra strength in the area where the nut pulls on. This is likely unnecessary but will make the change after work. As for my print, it lifted off the heat bed at the edges, so I need to reprint. July 16, 2017: After some digging, I found an issue with Rev2 where the middle screw's nut hits the optical sensors. To get around this, I'll remove those sensors for now and focus on printing a carriage that only needs two inserts in the center screws instead of ten. I'm working on finding a solution to address the remaining two issues. July 17, 2017: Rev3 is live! All brass inserts have been removed. I'm currently testing a part; fingers crossed it'll work as expected. July 18, 2017: After reviewing my previous revisions, I identified areas that needed reinforcement related to center screws. I tightened up the outer holes to 3.5mm from 5mm. July 19, 2017: Rev4 is here! Due to space constraints, I couldn't make the center nut work as intended, so I made some adjustments. I need to print and test this new version. It's possible that the CAD software is causing the carriage to be slightly off-center; hence, I created two different clamps – one with a half-moon design. Line it up with the corresponding feature on the carriage for optimal results. July 20, 2017: I've added a no-inserts remix of Jcen517's hot end carriage and need to work on duct issues. Henri suggests it might be too long. July 21, 2017: If you're dealing with X rods that are a bit short like mine, try placing shims in the x-axis clamp end caps to take up about 10mm of slop. August 8, 2017: X carriage clamp with teeth for hotends that tend to be loose. August 19, 2017: I've added a nice retainer for the hotend. The stock one was too loose for my Chinese E3D hotend, so I tightened it up and added a jam screw. Additionally, I included a feature in development for wire management using 1/4 clear flexible tubing. August 22, 2017: I've added a file that includes a small clip to hold the ends of the belt out of the way so they don't get caught in pulleys or have to be cut short. This seems to work as intended. September 16, 2017: I've added Henri's awesome Simplify3D table; however, I wanted to add the word "front" to the table, but Tinkercad didn't like it.
