3 filament holder and with 3 buffer in one Ikea Samla 22L box for ERCF and Voron 2023

I like the design, I would like to remix it a little though, would you be willing to share the CAD as STEP file?

This is the most consistent buffer I have tried. But there is one issue, I have printed a few of these and the buffer holder parts alignment is off. I finally saw what was the difference. If I flipped part b over it aligns perfect. Not sure what if anything I may have been doing wrong. Next I am building a dry box to hold them. (edited)

Instead of nails i used filament and it worked quite well
