Dear Kiran,
While I am not Phil I’ll try to answer your query.
I presume you are referring to the “BOMB-Community 2pt rack” by Malgorzata Cebrat ?
I have just had a look and the two individual components are both available in their respective files.
Please have another look and download them both by simply clicking on the pt1-stl and the pt2-stl buttons/symbols underneath the image and text (https://bomb.bio/protocols/ –> Magnetic Racks –> Printed racks).
Alternatively I can also email them to you if you would prefer that. (being the site admin I have your address)
Cheers
Tim M
