Hi,
I've created a small system for Ikea's Uppdatera Utensil tray to orginize Ikea's 35cl Spice Jars a little bit better, system consins of 4 elements, and can be as long as required due to it's modular nature.
You can find here STL files as well as STEP files if you'd like to edit, whole thing was created by using OnShape and is available here.
Attached gcode is as I printed it on my Prusa MINI+ with Input shaper.
The author marked this model as their own original creation.
