I have designed this model to add drawers to my setup. Having a small space i need to grow going up..

you can use this on top of the riser and his remakes or simply under the AMS risers stacking multiple units if you want.

I prepared different drawers with a different front plate. I also added a small tool box (still WIP) to use on the side if useful.

I didn't design internal separation modules for the drawers. I will add them in the future if the model is appreciated.

I used PLA. PRTG if fine as well.

if used on top of the BLV i recommend changing the AMS PTFE with a new one 10 to 15 cm longer.
