I like the overall concept and basic design of the model. That said, I needed to do lots of modifications to make things fit properly. On the main body (body1), The receiving screw holes for the PTFE side cutting tool were too large. The holes for the screw heads for the filament cutter tool were too snug and did not allow for free motion of the slide. On the filament cutter tool slide (body2), the receiving screw holes were too long and did not allow for the blade to clear the filament guide. On the PTFE side tool slide (body4), the hand press portion needed to be thickened as the screws protruded when the slide was pressed in. The receiving screw holes were almost double the size they needed to be. Those were reduced. The holes for the screw heads were too snug and did not allow for free motion of the the slide. The holes for the screw needed multiple adjustments; the tool slide stuck out too far, almost not in the main body. Once those were corrected, the tool functions great.

I remixed this for the larger container opening.

The side clamps are a bit too tight. On inserting them, the top part split a little.

had no issues. Easy setup. Looking forward to all the possibilities.
