Executive Summary

Anatomy of the Exshtender™

  • On one end, there is a foot that rotates +/- 15°
  • On the other end, is the grip which rotates from 0° to 64°
    • The bottom of the grip is the jaws which attach to the lip / bookstop of the shelf
    • On the top of the grip are the thumb tabs, which you push together to open the jaws when you attached the Exshtender™ to the shelf
  • Connecting the foot and the grip is the main body

How to USE the Exshtender™

  • Fold the shelf down
  • Pushing the thumb tabs together, slip the jaws over the lip / bookstop of the shelf
    • Place the Exshtender™ toward the side of the shelf, so that it isn't covered by your siddur 
  • Release the thumb tabs – the Exshtender™ should now have a firm grip on the lip / bookstop
  • Close the shelf
  • Lift the back of the shelf, and move the arm that is inside the storage compartment into the upright position
  • Raise the front of the shelf – the Exshtender™ should rotate into place automatically
    • You may need to give the Exshtender™ a little help the first few times until the joint loosens

Printing Tips

  • I have only ever printed these in PET-G
    • If you use another material, such as PLA, please let me know how it works for you
  • If the foot shifts off the bed before, put supports under the foot only
  • Getting the tolerances correct for the “Lego” in the middle of the main body is really tricky and varies from printer to printer.  I find that if you activate “Fuzzy Skin” in your slicer, it corrects the problem
    • I only activate fuzzy skin for the six pegs using PrusaSlicer's Add Modifier>Box feature
