Intro
Wouldn't it be nice to have a 3D-printed 3D printer? Well, I took that one step further. This 3D printer (modeled after a Prusa MK4S) has a moving x, y, and z axis! With an easy assembly, this is the type of toy you would want to bring to school to show off to your friends.

Differences From the Original
- Filament and filament holder added
- MMU3 added
- MUCH more detailed nextruder
- Wider frame
- Better print position for rods
- Better X-end clips
Print Information
For best quality, please print with organic supports on build plate only, I have tested this model with PLA and PETG, but other filament types could work well too. If you can, use 0.1 mm layer height for rods and 0.2 mm layer height for everything else. This allows the rods to be more round and fit better.
Build Instructions
Print parts and prepare tools
- 1 frame
- 1 Nextruder
- 6 Rods (2 of each length)
- 1 Heatbed
- 2 X–end clips
- 1 Hammer/Mallet
NOTE: Use the hammer/mallet to insert rods if needed
Assemble X-axis
- Find one X-end clip and slide in two of the medium rods into the holes on the side
- Slide the nextruder onto the two rods facing the bump on the X-end clip
- Fit the last X-end clip on the two rods facing the same direction as the first clip
Assemble Z-axis
- Take the X-axis and align it with the holes on the frame facing the same direction as the Prusa logo on the frame
- Take the short rods and slide them in the top holes in the frame down through the holes in the X-axis
Assemble Y-axis
- Find the heatbed and align it with the holes in the back
- Slide the long rods through the back holes in the frame
Attach filament holder (optional)
- Slide the filament holder through the top of the frame
- Fit the filament onto the sides of the filament holder
Attach MMU3 (optional)
