Clicky-Clack Fridge Door Dual Handles

Introduction

Because I found the original Clicky Clacky Fridge Door by whopping_Voron to lack sealing against the entire length of the frame of the printer, I've created this mod that splits the handle into two smaller units, as well as reducing the spacing between the door and the frame by 0.5 mm (to squish the foam tape a little). 

This mod can be done by reusing the original parts (dowel pins, bushings, bolts, magnets, etc), with the two dowel pins from the original handle being split into two separate handles, as well as using only one M3x20 for each Handle Hinge. The original handle uses two M5x7x8 bushings for the dowel pins, however, since the new handle is now split into two units, two additional bushings are necessary/recommended so both the top/bottom Handle Hinge of both handles have bushings in them. However, it is also possible to use only one bushing per handle by combining the top/bottom Handle Hinge with/without bushings as seen on the image below.

However, for the mod to work, it is necessary to have some additional hardware that is very common and shouldn't be an issue for most. This additional hardware is:

• 4 x M3x8 SHCS
• 4 x Ø6x3 Magnets
• 2x M3 T-nut or Roll-In

As mentioned above, I highly recommend getting 2 additional M5x7x8 bushings for all parts of the Handles.

Printing parameters

All STL files should be correctly positioned and require no support when printing. The parts need to be fairly strong, so I suggest printing them with the standard Voron settings, which are as follows:

• 4 walls
• 5 top/bottom layers
• 40% infill
• 0.2 mm height
• 0.4 mm width
• no support

Assembly

The assembly of this modification is almost identical to the original but with fewer individual steps. The assembled units can be seen in the included CAD (.step file) and can be used as an additional guide for the assembly. When installing the magnets, it can be a good idea to use a little glue to keep them in place over time. BE AWARE TO INSTALL THE MAGNETS WITH THE CORRECT POLARITY SUCH THAT THEY ALWAYS ATTRACT EACH OTHER!!

Hinges

The assembly of the hinges is identical to the original Clicky-Clacky door and can be read on its GitHub here.

Handles and Latch - Preparation

The handles are a little simpler to assemble than the original but have to be done twice since this mod split the original handle into two units. Start by pressing a Ø6x3 magnet and bushing (if used) into the Handle Hinge for the top/bottom as shown below.

Afterward, the middle part of the handle can be assembled by pressing in four Ø6x3 magnets and screwing in two M3x8 bolts into the plastic as seen below. Be careful not to screw in the bolts too hard as it only screws into the plastic. 

The handle can then be assembled by inserting the Ø5x45 dowel pin into the Handle and sliding on the top/bottom Handle Hinges, as seen on the image below. Because of the magnets, the whole handle assembly should snap satisfyingly together!

Lastly, the Latch can be assembled by press inserting two Ø6x3 magnets into it as seen on the image below.

Repeat the above again for the second handle.

Mounting the handles onto the printer

Now that the handles have been assembled and the Latch prepared with the magnets, it's time to install the handles onto the printer. This is done similarly to the original Clicky-Clacky Door, so if the following guide is confusing, I suggest watching some of the available videos on YouTube of the original Clicky-Clacky Fridge Door installation. 

Start in the top by mounting the latch onto the printer frame with two M3x8 SHCS and M3 T-nut/Roll-in. The handle assembly can then be installed on the fridge door by mounting it with an M3x20 SHCS and M3 T-nut/Roll-in in the top/bottom Hinge Handle as shown on the image below. The same procedure is done for the bottom handle.

The spacing between the two handles is as you prefer, but I'd recommend spacing them out (almost) as far as possible. With the door now having an additional handle, some adjustments might be necessary and is a matter of slightly loosening the handles and repositioning them again until the door opens/closes without binding. 

The final result of the installation should look something like this:

Optional Hinge for more foam squish

Because the handles are created with a slight squish of the foam sealing in mind (-0.5 mm), I've also created a new top hinge (Hinge L Bushing), which makes the door parallel against the frame when using these handles. Using these hinges gives a uniform compression of the foam seal across the entire door/frame. This is not mandatory but highly recommended! The assembly of this hinges is the same as the original Clicky-Clacky Door, so the instructions from GitHub can be followed for the installation. 

Final words

A big thank you to whopping_Voron for his original work and the entire Voron team for their amazing design. If you have any questions regarding this mod let me know. Enjoy! :-)

The original handle has been split into two separate and smaller handles to increase the clamping against the frame. All of the original hardware can be reused, however, some additional screws and magnets (and optional bushings) are required.
