Another one of my entries for the Creality Modification Master competition.

This is originally designed for the Ender 3 S1 (although I don't own one). I've found that the top extruded aluminium piece is the same as my Ender 3 v2. It has also proved useful when installed in other locations on my printer.

The modular bracket clamps on to the t-slot channel in the metal bar and locks in place with a quick release cam lever. I will be making a Reel soon to show how it works.

Modular system:
This was designed with multi-function in mind. There are many different slot in accessory holders (2 sizes of glue stick, small tray, paper/card holder, Allen/hex holder). However, it is also very simple for you to design your own accessories that will fit.

Printing:
The t-bar locking pin and lever need to be printed laid down with 100% infill.

The main body of the holder needs to flex/spring a little when the lever is being clamped down so I have used 2/3 walls with 10% gyroid infill.

I have found that PLA can be strong enough for this but PETG holds up better to the tensile strength required.

I have printed all parts together on a raft to keep the dimensions more accurate.
