Easy to print, no supports needed pegboard shelf brackets.  I use 4 to hold my shoes.  The shelves wobble so the combs notch into the end and base to add rigidity.  

• Printed in ABS
• Touch of CA/Superglue to hold when happy with position.
• Lightening holes to conserve plastic while maintaining strength.  
  • Rigidity of holes seemed to work better than trusses.  
• I use to hold sweaty running gear to dry; no rusting like metal hardware that corrodes steel.
