V-Core Titan Aero Mount

thingiverse

Update 24/05/19: Forget about my design, I'd encourage people to check out the linked design below instead; it looks much better than what I've attempted here. https://www.thingiverse.com/thing:3600079 This is an untested design, do NOT expect this to work yet - just sharing to see if people comment and provide valuable feedback. This is my first attempt at designing a Hotend Mount for the Titan Aero on the Rat Rig V-Core. I've taken the original Fusion 360 design and maintained the belt tensioner as base plate while adding the Hotend Mount as an individual part, making it easy to swap out if needed. The PTFE Tube holder is designed for the Threaded Bowden Coupling with a 1/4" thread - its intended purpose is to hold the PTFE tube on the Rat Rig frame and have tubing between the hotend and where I've placed the filament spool beside the printer. The idler lever on the hotend will take the other end of the tubing, designed specifically for that. The small cable mount plate is meant to hold the original E3D connectors for the thermistor and fan in place, as well as providing strain relief for the heater wires; it should fit my stepper motor with a cable tie, but I'm unsure if it will work with the original flat-pack E3D stepper. It's printed quickly and roughly in PLA with 15% triangular infill just to test the fit - the final print would be ABS or PC with more infill. To-Do List: I'll need to add some keying to the flat back, as the bolts alone won't keep it at a precise position once unscrewed and reattached. I'm also thinking of having the belt tensioner entirely separate on one side of the cart and using some form of metal cones or maybe even Delta type magnetic balls on the other side to have a reproducible precise fit and be closer to the center of the gantry with the nozzle and weight; possibly a spring pulling it in place instead of fixed bolts, as long as I have a shape for precise positioning. Update 07/05/19: I've now mounted my prototype design to the actual Rat Rig V-Core. It looks like I'll need to design it to bring the nozzle down a bit. The bed can't raise high enough for this because it was originally designed with an E3D V6 hotend, which has its nozzle closer to the bed. Also, in the mount base, I forgot to leave room for the heads of the bolts and the PTFE tube mount is too flimsy. I'll update the files as soon as I have a working design.
