Anycubic I3mega filament holder and guide

thingiverse

I decided to remake and redesign the holder and guiding of my I3 mega. At first, I printed a holder from creator McDos's design, but it seemed quite unstable to me. So I remade it from scratch and made some minor edits, allowing the right part to be mounted on top screws for better stability and preventing it from falling. After that, I realized that a universal roll centering part was needed, so I designed a cone-shaped part with a glued-in nut for a threaded rod, which serves as the filament roll center. You'll need two cone parts, glue-in nuts, and then you can screw them onto the rod as the roll center. The bigger cone base is 75mm in diameter, while the smaller one is 25mm, but it's designed to be universal, so I stopped printing when the smaller base had reached 45mm and even this solution is very versatile. So just stop printing whenever you want. The threaded rod should be 13.5-14cm long, with at least 15mm of thread ground away on both ends. This is because the roll will be moving and "screwing" onto the surface of PLA. After installing this whole stand, I had to reinforce it a bit with connection sticks - you'll need two pieces. And lastly, I added filament guides - one piece for the front stick and another screwed on bottom screws - check the picture. I didn't design the pulley wheel, which is actually the work of enry68 here: https://www.thingiverse.com/thing:2846692 All other parts are my designs. I'm planning to create a filament sensor holder, but for now, I've temporarily fixed it on the cable.
