This is a thinner variant of the original magnetic door closign mechanism.
It uses the original magnets, fixed with some glue.
It also uses short M3 brass inserts, instead of self tapping screws.
You need two A and two B pieces.
Printed in Galaxy Black ASA.
The author remixed this model.
The pieces are slimmer, also brass inserts for machine screws instead of self tapping screws.
