IMPORTANT NOTICE: Since Thingiverse was having performance issues and people are reporting getting 404 errors, I decided to place all my designs on my own website https://properprinting.pro/product-category/3d-print-files/ All files can be downloaded from there for free and all updates and new designs are placed on there too.

I started my 3D printer upgrade series with the quick tool change https://www.thingiverse.com/thing:3369444 which is still one of my coolest upgrades. However, it missed something because if you change to a different tool, you always have to place the hot end somewhere. With the swappable hot end it is possible to disconnect the whole hot end like the Ultimaker printers. Another advantage of this, besides being able to disconnect your hot end, is that you can use different hot ends for different materials or nozzle diameters. After I came up with this idea I found a couple of similar approaches but nothing with which the bowden tube itself could be disconnected.

Another cool thing: if you use a laser engraver, you don't have to add an extra wire or switches to your control board and you can just connect it directly. The coming weeks I will work on this.

If you don't want to get through all of this trouble and risking breaking down your machine, but you want this upgrade: I am thinking of selling a set on my website if enough people want this. This set will be included with the cable which can be connected to the control box so you don't have to cut anything. Let me know if you are interested by leaving a comment!
