Hardware Required for (1) Drybox:

Hanger

• (6) M4 x 12mm screws (I prefer button heads for this)
• (6) M4 nuts

Center Bolt

• (2) M4 x 12mm screws (I prefer button heads for this)
• (2) M4 nuts. Optional depending on the version you're printing - nut version is recommended.
   

For the center bolt and nuts, I recommend:

• 4 perimeters
• 0.2mm layer height
• 20% grid infill
• I used a 0.6mm nozzle
   

For the hanger, I recommend:

• 4 perimeters
• 0.25mm layer height
• 20% grid infill
• I used a 0.6mm nozzle
   

For the center pins, I recommend:

• 4 perimeters
• 0.15mm layer height
• 15% grid infill
• RANDOM seam position. This helps to reduce friction from a single, large line of seams.
• I used a 0.4mm nozzle
