# Printable quick release latch for panels on 2020 extrusion
|
|
|
|
*I wouldn't say no to a like and a make on printables if you're that way inclined -

https://www.printables.com/model/172368-voron-24-filament-latch-or-any-2020-extrusion*
|
|
|
|
## Intro
|
|
|
|
This is originally inspired by a youtube video - [https://www.youtube.com/watch?v=6p7M18oPn3k](https://www.youtube.com/watch?v=6p7M18oPn3k)
|
|
|
|
Another user is creating cad and variants - [https://github.com/v6cl/My-Voron2.4-Customs/tree/main/Panel_Locker](https://github.com/v6cl/My-Voron2.4-Customs/tree/main/Panel_Locker)
|

|
## So why did you do it?
|
|
|
|
1. I wanted a variant with filament hinges
|
|
1. I found it didn't put quite enough pressure on the panel and my attempts to moodify the cad failed
|
|
1. Decided the best way to understand it was to design it
|
|
1. Wanted adjustable "pressure" and thought using a sweep on the latch was a nice solution making the most of the flex of ABS
|
|
1. Wanted everything as a parameter so I could tune it
|
|
1. Build plate density, a bonus of using a filament hinge is that the area used for each hinge is much smaller
|
|
|
|
|
|
|
|
45 instances on a 250 buildplate
|
|
|
|
## Hardware
|
|
- 3.0mm-5.5mm - m3x12
|
|
- 6.0mm-8.0mm - m3x16
|
|
- 8.5mm - m2x20
|
|
|
|
## The process
|
|
|
|
1. Cad attempt one failed, just modified surfaces to create a filament variant but adjustement beyond that failed
|
|
1. Cad attempt two failed, created a traced version copying the dimensions but again couldn't get a reliable adjustment
|
|
1. Cad attempt three of the cad sketch made as built was finally onto something, took until v45 before I had something that seemed to fulfil my requirements, then after thinking overnight revisited earlier designs and finally hit RC at v68 (18 actually printed)
|
|
1. Final design and thankfully discovered [sheeter](https://n3rdlab.com/downloads/sheeter/) which allows me to produce many stls based on parameters
|
|
|
|
## Assembly
|
|
|
|
|
|
|
|
1. Print parts (do test prints to ensure you're happy with the fit before going wild)
|
|
1. Assemble to correct orientation
|
|
1. Insert two short filament lengths connecting middle hinge to hinge body, one from each side
|
|
1. Insert one long filament length connecting middle hinge to outer hinge
|
|
1. The filaments are a tight-ish fit on the hinge arms but loose in the pivot intentionally
|
|
1. Connect to frame using with hammer nut or spring loaded nut with either m3x12 or mx16 depending on size of hinge printed
|
|
|
|
## Parameters
|
|
|
|
To make your own custom hinges you can modify the parameters in the cad - via Modify -> Change Parameters. Removing the logo just requires
|
|
you to supress the logo extrusion (last extrusion in the first group).
|
|
|
|
Changing these parameters to extremes may either not work or require fixups of chamfers and fillets, or even the primary sketch.
|
|
|
|
|
|
|
|
Once done, adjust the build plate view (use top view to ensure clearance) and save the file as mesh.

## Changes
|
|
2022-02-11: Added detent from devincody
|
|
2022-07-29: Reworked sketch to resolve in Fusion 360, re-exported fixing some incorrect sizes
