The Exshtender, Premium Edition

Updates

SUN 11 OCT 2026

• Added photo of Exshtender "seen in the wild" @ LMS just outside Philadelphia
  
  (Sent to me by a friend of Yosef Shraga's Tati)
  
  

• Updated the arm to version 7.4
  
  The arm now locks into place.  It means that you have to manually disengage it, but it prevents accidental disengagement
  
  

• Replaced the .stl files with .3mf so that you don't have to paint on the fuzzy surfaces
  
  The fuzzy surfaces make the ogel interface work better without having to super-calibrate your printer

Executive Summary

• The major difference is that the Premium Edition raises the shelf (and your siddur) about twice as high as the regular Exshtender™

  • To do this, it adds a second piece, the arm that raises the other edge of the shelf as well

• The Premium Edition also has two feet – the second foot engages when it is “folded” to give the same performance as the regular Exshtender™

Modes

There are five configurations (described below).  The pictures should be in this same order:

• This is how the Shtender looks immediately after installing the Premium Exshtender™, also known as the “L” Exshtender™

• If you fold the shelf, it does not fold all the way, but stops at a slightly increased angle

• If you lift the back of the shelf and move the arm that is inside the storage compartment into the upright position, you get the exact same effect as using the Regular Exshtender™

• If you attach the “Arm” Exshtender™ to the back of the shelf, and extend it, the shelf will be horizontal, but higher than normal

  • Note: the arm has two similar feet because the back wall comes in two different thicknesses, depending on when you bought your Kibbutz Lavi Synagogue Seating System.  Use the one that is a snug fit

• The you lift the front of the shelf, the “L” Exshtender™ will swing into it's fully position, giving you the maximum height extension of the shelf
