Ontos Side Rails - Inserts Remix

This is a remix of the middle piece of the Ontos Side Rails with widened holes to accomodate M3x4x5 inserts to try and make the connection sturdier (since I will be using it to attach a sling point) and to make it easier to assemble and disassemble without stripping plastic parts.

It requires four (4) M3x4x5 inserts.

Update 2025-12-14

Added both left and right rails files since they were not uploaded as single files in the original design.

I have widened the holes to 4.5mm to be able to use M3x4x5 inserts and make it easier to assemble/disassemble without stripping the plastic parts.
