3D Toolhead - Printer Pen Holder

thingiverse

I made this project to use on my Grabber i3. Part of the project was to create a way to easily replace different toolheads on my 3D printer because I want to create new tools in the future. The original mount of my extruder was made with two pieces of MDF, holding the linear guides as a sandwich. The extruder bolts pass through one of these pieces and are locked with a nut inside, making this really tricky to unmount. So, I left this project with the STL file for the tool holder that I created for my 3D printer. I locked this piece on my original X-axis and put an M3 nut inside. If I wanted to change the toolhead, all I need to do is unscrew one tool and put a new one. To use the pen holder, you will need to use an elastic. This will act as a spring holding the pen against the paper. --------------- I made this project for my Grabber i3, which needs adaptation for other models. The idea behind this project was initially to allow multiple tools for 3D printing, making it easy to swap out the extruder for another piece without much difficulty. I started with this pen holder project. This project consists of three pieces: the body that will be attached to the X-axis, a small plate that passes through the body and where two clips are screwed in to hold the pen. This allows the pen to move freely up and down. The two small hooks were made to allow the entry of an elastic, which acts as a spring holding the pen against the paper during printing. This ensures that the pen does not move away if the table is slightly tilted.
