Project Overview:

I began 3D printing a few months ago, starting with small projects and gradually moving to more complex ones. This combination of models has been my most ambitious project to date, aimed at enhancing my skills in model making and modification. I enjoy creating physical items for my D&D campaigns and Ren Fair costumes, finding that they add a layer of immersion and enjoyment.

Combination Process:

SunSword Preparation:

Download and Resizing: I first downloaded the SunSword model, as it was the cleanest version available. The model was too large for my print bed and for some other sword models I considered, so I scaled it down to 66% in my slicer software.

Collapsible Sword Integration:

Model Selection: I tested various sword models to find the best fit for integration with the SunSword, ultimately selecting the Collapsible Sword model. This model required minimal alterations to the SunSword and balanced well in terms of blade length and hilt scale.

Alignment and Modification: I aligned the two models and used two modified cylinders for the integration:

First Cylinder: Encased the collapsible blade, replacing the original handle to fit within the SunSword’s handguard.

Second Cylinder: Slightly larger than the blade dimensions, it was used to carve a section out of both the first cylinder and the Sun Sword model.

Model Combination:

Assembly: I combined the sword model, the first modified cylinder, and the SunSword model. The combined model was then put back into the slicer for further adjustments.

Cutting and Pinning: The handle was cut in half to keep the collapsible sword intact within the SunSword. The pommel was shortened due to height constraints, and pins were added for easy reassembly with glue.

- Cap Modification: - Scaled the guard cap up to 102.50%

- RECUT 3MF Supports: - Be VERY careful as the supports that connect to the blade tip are very small and fragile, if the blade does not extend all the way on the first time there is a possibility that the support that connects to the blade tip can become logged inside the model if the tip is the only part that collapses down into the handle and provide a slight rattle. This may also cause the blades to not properly collapse all the way down as they end up being slightly recessed.

- Cuts if using full model STL - Starting from the bottom up - 1st cut: height 42.78 - 2nd cut: height 188.27 - 3rd cut (if needed): height 171.14 - You are welcome to cut the model however you like, this is what had worked for me - Do be careful when cutting around the handguard and a few inches into the handle as you do not want to disturb the collapsible blade within and have issues arise. - Custom Cut - Honestly Cut it however it will best fit your printer, The main part to be careful about is the blade, when cutting start by separating the hand guard/handle and the lower handle/pommel then continue cutting however necessary. If someone finds a good way to cut the model so that blades can be printed separately please comment and share the post to the threat here. Additional Features:

Resin Gem Mold/Negative Gem Mold: A negative mold model allows for casting a custom resin gem in any color. Use hot glue to seal the thin corners, fill with mold-making silicone, and once cured, cast the gem in resin.

Assembly From 3MF Files:

- Make sure the blade functions as it is supposed to and slides all the way out to full length. - The connectors along the side of the print in place sword section end up being pretty snug so don’t be afraid to sand the down a bit or carve away a small amount of material on the connecting holes for the wings as well as using some physical persuasion. Finishing Process:

Assembly and Priming:

Glue all pieces together and tape off the blade section.

Apply Rustoleum filler primer

Apply some form of spot putty to fill in the seams and cracks if you have any.
