Modular stand up bookend

This model is a total redesign loosely based on my previous model but with major improvements:

• The block pieces are now simmetrical so the orientation does not matter during assembly
• The block pieces are lighter and longer
• The block pieces come in tho thickesses: 5mm (thin) and 10mm (thick)
• The connectors to put togheter multiple pieces are now the ones from the cube gears by emmett, they are easier to use and provide a stronger connection
• I included more length of bases compared to my previous model and already included in the “modular bookend.3mf” file there are multiple plates of block pieces to be able to make enough of them per each size (you will find the number you need in the included “pieces per size.txt” file)

The included “modular bookend.3mf” file was created in Orcaslicer. The file is made for an X1 Carbon and a .6mm nozzle. If you'd like to use different settings here are some suggestions:

• Use Lightning infill with a 30% density as this model does not need to support more weight than its own so you can save material
• Go slow for the first layer, I went for 20mm/s to make sure that everything stuck well to the plate I was using
• Because of the Lightning infill you might want to increase the number of perimeters if you are using a smaller diameter nozzle, since I was using a .6mm and 3 perimeters already I did not find necessary to increase wall thickness but if you are using a .4mm you might want to increase the number of perimeters to 4 to have slightly thicker walls and more rigidity
• Disable support, they are not needed
• Be sure to have your elephant foot compensation dialed in as an elephant foot will impact the fitment of the block pieces on the rod

If you need a size which is not included you can easily modify the model since the recesses in the model are mede to allow easy cuts at 50mm intervals (I suggest cutting it from the center) and the sockets for the pin do not extend inside the first recess, they should be around 15mm deep.

UPDATES:

• Modified the geometry of the channel where the block pieces are to better follow their shape to reduce sag
• Added a 190mm option for both bodies and ends especially designed to be used in the IKEA BILLY whide 80cm (you'll need 4 to cover the internal width)
• Changed the angle at which the blocks sit while not engaged to prevent them being stuck when trying yo insert a book
• Added a double thickness block piece and updated the .txt file to reflect it

Changes made for v2

• reworked the shape of the block and main body to fix the blocks height at rest, the v1 ones would not sit at the same height for some reason so this new version should fix it and the variation of height should be greatily reduced

Assembly instructions:

Slide the rod inside one of the sides and start putting the block pieces in like this

Then If you nedd to connect different bases between each other puch the pin inside like this

And then puch the parts together to connect them.
