Qiagen tip 2500 mega maxi prep adapter
I remixed the previous design by removing the flat cap to avoid having the prep cartridge touching the PLA.
The bars are reinforced for lasting longer in time.
The screw fits a falcon 50mL tube and hold the qiagen tip 2500 on it.
I printed in PLA @ 0.36mm per layer, printed top to bottom (upside down, cap on top and the side where you put the qiagen tip on the bed)
