This is a 12 gauge/70mm Shell Cut Away, model. These don't NEED supports, although, I use PETG support on the brass head for the lettering on the case head. you don't have to. Also, make sure you're printing with the shell body facing down, otherwise it will print a TON of support to print the roll crimp. Use a Quality hobby grade CA glue for assembly. Do NOT use cheap gel glue from the store or it WILL frost the parts as the glue off gases during curing( Loctite, Gorilla brand, etc). If you experience some off gas hazing, a tiny rub down with petroleum jelly, followed by a good wipe down with a soft cloth will make it look good as new. Unfortunately, I don't have assembly pictures and all of mine are assembled. I will try to update/ add assembly pictures later when I print another model.

Assembly is pretty straight forward. Just referencing the picture will give you a pretty clear idea. Generally, I assemble as follows/ here are some tips:

• Assemble the primer separately and allow to dry before gluing it into the brass case head
• Assemble the stuffing, gunpowder, bottom of the wadding into an assembly
• Use the assembled primer/case head as an alignment tool to install the wadding/gunpowder assembly
• Slide in from the bottom of the shell body, align and glue the sell cap into the shell body
• Slide the Wadding cup into the shell body, glue/align to your liking
• loosely place the wadding cushion( the X-shaped piece) in the brass case head assembly, slide the shell assembly down. add a few drops of glue and adjust the position. Honestly, the wadding cushion can go either way, but, the large gap side of the X usually faces, down.

Lastly, the shot is sized small. if you increase/decrease the scaling on the shot, you can go down to birdshot OR Buckshot as pictured. Use a brim when printing the shot, they come out better. I glue the 3-shot ball sets in after the entire rest of the model is assembled. I loosely place them into the shell and orient them as desired. The 3-ball sets will orient easily based on the shape. I use THIN OR MEDIUM CA glue with a fine point applicator to place a drop between the contact points, while they are inside the shell, as it will wick into the joint easily.

Filaments I use:

• CC3D PLA Silk- Bronze/ Brass(Case)
• SunLu PLA - Red (Shell Body) Any color can really be used for this, green and black look really fantastic, too.
• SunLu PLA - White ( Wad components, Shell Cap, and Stuffing)
• CC3D PLA Silk- Gold/Copper( Primer Cup, Primer Anvil, and Brass Case)
• Creality/Giantarm-PLA-Black or Dark Grey( Gunpowder)
• Creality PLA- Grey or Black( Shot)
