Rectangular vs Square hole for magnetic closure

[Flyrail47]

I'm converting a velcro FOTK build into a magnetic one. I'm thinking about using rectangular magnets for the chest, back, and shins since I don't have the tools to drill holes for circular magnets.<br><br>

In terms of long-term wear & tear, is there a significant difference between the strength of rectangular vs circular holes in ABS? <br><br>

I'm thinking that, in both situations, the magnets will put stress on the seams of whatever hole they're in from moving etc.<br><br>

If anyone has any advice or experience on the matter i'd greatly appreciate it. Thank you.

I would say that magnet attaching as a whole isn't very practical for larger areas like what you're talking about, especially if you're twisting and turning a lot which could separate the magnets without any stretching. If you must though, always go with round or circular cuts; rectangle/sharp edges on abs is always more likely to succum to cracking and breaking.

I thought so too. Thanks a million!
