Stronger Snap Latch with M3 Screw

Tip

Because any voron builder has tons of spare M3 screws!

You will find here a set STL to make all the panels of your voron removable:

• Strong Snap Latch for better insulation
• Corner for the panels that works with snap latch
• Exhaust Cover with no screws, to use with snap latch
• Removable Doors

Original Designs

This repo is based in the amazing works from:

• Original Snap Latch: https://github.com/VoronDesign/VoronUsers/tree/master/printer_mods/richardjm/snap-latch-2020
• Snap Latch for M2 Screws - where I take the cad to modify: https://www.printables.com/model/643837-wide-voron-panel-snap-latch-with-lip-using-m2-scre
• QD Panel Mod, uses M1.6 and M2 Screws - where I take the corners to modify: https://github.com/MotorDynamicsLab/VoronQDPanelMod

Motivation

M2 and M1.6 screws are very hard to find on local stores, at least where I live. And it takes a lot of screws to cover every side of a voron!! So, it would take weeks of waiting to get all thoses tiny screws.

But I have tons of spare M3x8, M3x10, M3x12, SHCS and BHCS, from my voron builds. And I thing most of voron builders have it too. So I modified these designs to fit with our spare screws!

I found the current designs a little weak too, to really squish and insulate the panels.

Modifications made:

• Suport for M3 Screws. It works with either 8mm, 10mm or 12mm, both SHSC and BHSC. You can even mix screw sizes!
• Outer Hinge with a Straight line: The orignal design uses a curve for the outer hinge sweep path. It makes all the pressure be concentrated in just a few milimeters of plastic. I changed it to have a straight line in the middle, so it distribute all the pressure in a wide area.
• Stronger outer hinge - 8mm diameter instead of 5mm: I adjusted the cad to allow customize the outer hinge diameter. It allows to apply far more pressure to the panels without any plastic fadigue.
• I modified the corners for QD Panel Mod to fit better. The original design didn't hold strong in the frames for me.
