Hi! i spent a while working on this as a halloween costume and thought i would upload it for all of you

What You Need: you need four of the “iron spider arm connector” four of the “Iron Spider Arm Bend V2” four of the “Iron Spider Arm Arm Piece" four of the “iron spider arm tip V2” one of the “iron spider backpack V3”.

Parts List:  MAGARROW 24" 40" 60" 100" Strap Buckle Packing Straps Adjustable 1-Inch Belt, you need it in yellow and the 24" long, Magnets doesn't necessarily matter the size but as strong as you can get, Gorila Super Glue (OPTIONAL) Gold Spray Paint, depending on the color you want or if you make it in one solid color filament wise that's up to you.

Assembely:

 Secure the Backpack
Make sure the backpack is held firmly in place so it doesn't move or wiggle during the process.

 

Attach the Connector Piece

 

  • Apply glue to the tip of the connector piece.

     
  • Insert it into the backpack. You may need to lightly hammer it in.

     
  • Make sure you're inserting it with the correct orientation: the arm should face outward.

     

Attach the First Arm Arm Piece

 

  • Apply glue to the end of the arm arm piece.

     
  • Insert it into the bend.

     
  • Lightly hammer it if needed to ensure a secure fit.

     

Connect the Other Side of the Connector

 

  • Apply glue to the other tip of the connector piece.

     
  • Insert it into the bend you just attached the arm arm piece to

     

Attach the Arm Tip Magnet

 

  • Apply glue to the tip of the arm piece

     
  • Attach a magnet to the tip.
  •  
  • Check the polarity to make sure the magnets attract and stay connected properly.
     
  • (Alternate) you can use velcro instead of magents

Repeat

 

  • Repeat all of the above steps for each of the four arms.

 

If It Breaks: make sure you GENTLY really gently hammer in the pieces so they dont break if you do have a piece that breaks if its the arm arm or connector glue over the surface and hope for the best, if its a bend that broke saying it broke at the hole lay a bit of glue over the crack and again hope for the best.

Final Note: this took a really long time to make and i really hope you appreciate it, i incourage you to create custom tips so you can either create different charecters or what ever you want, i hope you dont run into any problems if you do feel free to tell me and i will do my best to fix it i don't check printables to to often so it may be a while before you get a response, farewell and goodbye.
