This is a revision of an OpenLock Clip that adds an additional 3x4mm magnet, and flips the direction of the magnets for strength and grip for heavier terrain items (this was helpful when using 3x3 tiles).

• Printed in Inland PLA+ on a Prusa i3 MK3S
• 20mm quality print setting preset
• Takes about 3h 30m to print 64 instances of this model on the MK3S

Remember to install each magnet in the same direction! Getting them out is near impossible :) 

Requires 3mm x 4mm barrel magnets sold here: https://www.amazon.com/gp/product/B075PM7HZ6

The OpenScad file used to remix the original clip is included, in case you want to use a different magnet size.
