Parametric Panel Latch for 2020 extrusions and Voron using Steel Spring Wire

The original design using ABS/PLA filament for the hinges and works great until the filament eventually breaks. This version uses Stainless Steel spring wires for hinges, and the arms are thickened for longevity.

I have also included  the Fusion360 drawing. This model is built with Parametric design in mind and can be customized to your liking as follows; the dimensions in parentheses are the defaults:

• Pin_dia (2 mm) - The holes for passing the Steel wire through all the parts. The included STLs and drawing assuming 1.6mm steel wire and “space” so no post-processing drilling required.

• Main_Body_Width (30 mm) - The width of the screwed/fixed part.

• Felt_Thickness (1 mm) - Felt/insulation used to make the plexiglass airtight.

• Plex_Thickness (3 mm) - Thickness of Plexiglass or any other panel material used for the sides

• Tension_Bar_Depth (2 mm) - The higher the number, the tighter the hinge will close. I found that 2 mm is good for PLA and 2.5 mm for ASA printed hinges.

I used a soldering iron with a flat point to slightly melt the ends and close the holes, so the wires will not come out.

From the file list below please pick the following 3 pieces per hinge.

1. Outer_Hinge

2. Main_Body

3. Choose one of the Mid_Hinge_???? which the Voron Logo displays correctly for the position of this hinge. For example, if it is placed on a vertical extrusion then decide either Mid_Hinge_Left or Mid_Hinge_Right depending on your preference.
