Ender 5 Cable Chain and Bowden Tube Management system and Gantry Covers

Last crawled date: 4 years, 1 month ago

In my ongoing implementation of TeachingTech's Ender 5 enclosure (https://www.thingiverse.com/thing:3862902), I wanted to design covers to protect the moving gantry under the brushes. That cover then became the natural place to affix cable management components.
One aspect of my design is to have the Bowden tube and the hotend cabling handled separately, because I have found that they have very different bending capabilities, and it is convenient when working on just one of them to not have to disassemble the other. So:
Motor side: We have two cable chain adapters for johnniewhiskey's Ender 3 Cable Chain (https://www.thingiverse.com/thing:2920060), one leading outside the enclosure to the electronics box, and the other leading inside the enclosure to the hotend. There are separate channels for the x-axis motor and the x-axis endstop, along with slots for cable ties. This is a difficult print in terms of supports due to the spindly bits, but it can be done. I would appreciate any advice on how to improve the printability of this part.
Far side: I have moved my extruder to this side. I found that the Bowden tube needed some loose support to keep it from getting caught on the gantry. The tilted, wide-open guide for the Bowden tube allows the tube to slide in and out easily, slide front and back within limits, and keeps the tube clear of anything it could catch on. This piece is printed in two parts that snap together. It may be necessary to glue them once I get the nylon brushes in place.
