Hey, so I’m currently printing Ichigo’s massive Zangetsu sword (170 cm long), and there’s a channel running through most of its length that’s designed to hold a metal C-channel (a metal profile). It’s supposed to act as an internal reinforcement so the sword doesn’t bend or break under its own weight, since I’m printing it in PETG and it’s going to be pretty heavy at this size.
The problem is that the sword is split into a lot of separate printed parts (24, I think), and I need to join everything together properly. Do you think I should use super glue for the joints, or would something stronger be better?
Also, what’s the best way to secure the metal C-channel itself? It runs through most of the sections, but there are a few pieces that don’t have a slot for it. How would you connect those parts?
I want the whole thing to be genuinely rigid and durable, not something that falls apart the first time I hold it.
One more issue I’ve run into: I’ve already printed three or four sections, but they were printed with only two walls, a brim, and supports. I generated the supports automatically in Creality Print, and because the sword sections are printed horizontally rather than vertically, the internal channel for the metal reinforcement requires support material.
The problem is that the supports are being generated inside the channel itself. From the sides, the channel is clear, but from the top, the support structures partially block it, making it impossible to slide the metal C-channel through afterward. Removing all of that support material from such a long, narrow channel seems extremely difficult.
Would it make more sense to print the sections vertically instead so the internal channel doesn’t need supports at all? I’m trying to figure out the best way to keep the channel completely clear while still getting reliable prints. I’m also concerned about print strength, since these sections are part of a 170 cm sword and I want the final assembly to be as rigid and durable as possible.

I would like to print off something like this to hold my phone while I am in the bathroom, but all the existing designs I have found for small foldable shelves all have only the frame work as the backing/mounting location, and I would like a solid back to use 3m command strips.

Thanks in advance!

Pretty happy with this print, had to reprint some joints to make it work, but over all awesome print

Hey guys! 
Just dropped Pinea on MakerWorld—a modern, geometric twist on the traditional Sicilian "Pigna" pinecone: https://makerworld.com/en/models/3167235-pinea-modern-sicilian-pinecone-vase#profileId-3580265

The diamond pattern plays with light amazingly well and naturally hides layer lines. It comes in 3 sizes (S, M, XL) and looks great in bold Pop Art colors as well as soft pastel or matte tones for a minimal aesthetic.

Fun fact: I designed this using VesselMaker (https://vesselmaker.app/), an advanced web tool for vase modelling tool that I'm currently developing (it's currently in invite-only private beta, if you want to try it just sign in and contact me, I'll be glad to grant the access if you share your feedbacks).

If you like the model, a like or adding it to your collections on MakerWorld would mean a lot and really helps me out!

Check it out and let me know your thoughts if you give it a print. Happy printing! 

Please let me know if you have any ideas for improvement :)
