Voron 0 RTV Easy Application Tool

Hello!

This is a tool I came up with to help myself apply RTV silicone on my Voron 0.2 bed from FYSETC.

Some people recommend applying RTV silicone on your Voron 0 bed in order to extend the life of the bed (the glue may not hold to the bed well at high temperatures after many hours of printing) and also for fire safety.

However, applying something so gooey like RTV is always a mess and always makes it a stressful experience. With this tool I hope at least now you can do this easily and quickly!

Recommendations:

1. It's an easy two-part print that should fit any standard sized bed. Layer height is up to you, it really doesn't matter.
2. Print both parts upside down for better quality on the slopes of inner sides where the RTV goes in.
3. Apply some mold release agent (like candle wax, petroleum jelly, or cooking spray - check compatibility with your RTV) along the RTV pass to help release the form later.
4. Use 3 M3x6 bolts and nuts to fixate the tool on the aluminum slab.
5. Apply your RTV silicone along the gap to cover the heating element and the part of the slab.
6. Use a plastic card (or any other similar tool) to even the layer and distribute RTV along the passage. Try to move your hand along the whole line in one take to avoid inconsistencies and apply a bit of pressure to distribute your RTV and get rid of the extra goo.
7. After the initial application wait for around 5 minutes for RTV to start drying and then slowly and carefully holding the tool on all sides lift it up. If you aren't sure try to slowly unscrew the bolts - if the RTV starts to drag with the bolt - it's ready.
8. After 24 hours, the RTV is dry and you can use a blade or paper knife to cut off bulges and remains of uneven application.

P. S. Please don't mention the top right and left corners in my pictures - I f'ed it up myself already after I lifted the tool =D. I didn't have another Voron 0 to retake the shot, but maybe next time. =D
