FrankenFoot

(aka 4040 extrusion mounted tall leg with damper mount)

I seem to always run out of room on my desk, so I wanted to take my Ender 3 Pro vertical to provide additional space under the machine for larger bays and storage.

The goal of this project was to create the following in a leg design for my Ender 3 Pro or any other 4040 based printer:

• Strong and stable
• Connect via the 4040 extrusion
• Create additional space for drawers and organization under the machine through added height
• Integration of vibration reduction
• Not (overly) ugly

I am new to 3D printing and modeling, so I took three different designs I liked portions of and remixed them together in tinkercad. Hence, I present you with the FrankenFoot.

This model adds around 45mm of space under the 4040 mount without the damper and 55mm with the dampers (this is the final height with the printer compressing the dampers on my machine, this may be different based on your printer settings, weight or dampers used). It can be used with or without the vibration hemispheres that are listed above. There is enough room on the bottom that you could put your own bumpers instead to have a similar anti-vibration effect.

This design utilizes 4 x M4*12 bolts and 4 x M4 T-Nuts.

My plan is to remix some of the drawer and rear enclosure designs at some point in the future that take advantage of the additional height. I’ll link those in as they are created.

I have these installed on my own machine and will update the design as it is tested. This is a very new design, so use at your own risk.

Since these are structural, use settings for your printer that you know and are sound. These need to be able to support the weight of your printer and the vibration caused during printing.
