Blind plug for Core One rivet mounting holes

A minimalistic blind plug that can be used to close any holes that are left when not using the original rivets. Minimum filament consumption, ca. 0.1 g per unit.

I have my Core One top cover fixed with the magnetic holders for quick and easy access and thus do not use the rivets. This leaves their mounting holes open so I made these plugs to close them :) Plugs shown on the pictures are printed in Prusament PETG Galaxy Black using standard 0.1 mm structural settings.
