Strong Customisable Bag Clip, PLA compatible, PiP

Summary

A strong Customisable Parametric Bag Clip that is PLA compatible and Print in Place.
 

I wanted a script that would produce clips that are very strong but wasn't sure where to start. I wanted the clip very customisable so I could produce normal thinner type clips that save filament, as well as very robust clips for heavier jobs. Thanks WRonX for helping me learn about extrusion operations.

I ended up with a very customisable clip, flexible in design and very strong in, well... strength, when desired.

• Option to make the clip double channelled by stacking two together - this makes a very strong clip and is the default setting
• Option to add stiffening ridges on the back of the arms, letting you reduce overall arm thickness while maintaining rigidity
• Customise the size of the rib and channel along the arms
• Optional chamfer to both sides of hinge to help with first layer
• Changed parameters for some difference() operations so the cuts are more parametric with all tolerance and parameter settings
• Optional chamfer on the end of the free arm
• v1.1     03 Jun 2026
• Added option for customisable length extension on latch to make opening easier with thin clips
• Added sanity check to ensure channel width/depth does not exceed arm width/thickness

You must carefully consider your printer capabilities when tuning parameters and tolerances.
