Description

From the underworld of style.

 

Meet the Boookenstack, a frightfully fun, support-free, modular, 3D-printed TPU sandal, featuring stackable sole layers for:

  • adjustable height
  • customized cushioning
  • selectable stripe count

 

Designed for support-free printing, every layer prints cleanly on its own — no trimming, no wasted filament, no post-processing nightmares. Just print, snap-fit, and slide your feet into comfort.

 

Whether you’re dressing up for Halloween, cosplay, or just looking for a comfortable, supportive sandal, you can lay your feet to rest in the Boookenstack.

 

Features

  • 🪦 Support-free print – designed to rise clean, no supports or sorcery required.
  • ⚫⚪ Stackable sole layers – alternate black & white for Beetlejuice stripes.
  • 🧱 Modular fit system – adjust height and cushioning by adding or removing midsole layers.
  • 🌈 Customizable colors – print parts in different colors without needing an AMS. 
  • 🦶 Contoured footbed – comfortable arch support and roomy toe box.
  • 🧩 Snap-fit assembly – quick to print, easy to customize.

 

Suggested Print Settings

  • Material: TPU (Shore 95A recommended)
  • Layer height: 0.2 mm
  • Infill: adjust infill density for weight and stack height - 10% gyroid works for a 150 lb person on a 6-layer stack)
  • Supports: None required 🎉
  • Orientation: Print each layer flat on bed
  • Assembly: Step on the stack to snap-fit together

Almost three months of wearing them every day – so – update. I had to reprint the straps on both after a while, and today I printed new sole parts because the sole clips simply broke off. I'm very pleased. These are the most comfortable flip-flops I've ever printed. The best part is that if something starts to tear, you can simply reprint a new part and that's it.

My wife needs a 1 cm raise for her left shoe. This is easily solved with these sandals. Simply brilliant! Thank you for your work and for sharing.
