Container (PET thread) w/magnet for tiny screws

This is remix (thread section) of https://www.thingiverse.com/thing:3135497 (thanks for sharing). Very useful container for keeping tiny screws when dismounting small electronic devices (like phones, cameras etc). Every electronic hobbyist knows what does it mean, when tiny screw falls to the floor in the workshop. I've prepared 4 versions, round and square (anti-rolling) base, for 2 kind of neodymium magnets (square and round):
RB --> round base (diam. 30mm),
SB --> square base (30x30mm),
RM --> round magnet (5x1mm),
SM --> square magnet (5x5x1mm)

Magnet allow to keep screws inside , but also to stick the container to the metal surface - especially when using a stronger one (N50).

Printed in PLA, nozzle 0,4mm, layer 0,2mm, no support.
Magnets guled with CA or epoxy.
