This model is only compatible with the Prusa Core One/+

Assembly Instructions

Printing tips

-  PLA / (PETG)

I printed all the parts in PLA, and the mechanism works perfectly, but you can print it in PETG for added strength.

But, the integrated supports don't hold up well with PETG. You'll need to add your own supports using the parts from the “Individual Parts WITHOUT support” file.

If you have both, I recommend using PLA

-  NO support (only with PLA)

You don't need to add supports to the parts, because I've already built supports into the models !! 

But if you want to add your own supports (to use PETG), take the parts from the “Individual Parts WHITHOUT support” file

-  3 perimeters to make the parts strong

-  15 % infill

-  OPTIONAL, depending on your bed’s grip :

A border for long pieces (3 mm) to prevent them from warping (“Crossbar”)

But do not exceed 3 mm for the “Crossbar,” otherwise the part will not fit on the bed

Files

There are 2 files that group together parts of the same color

"Stationary parts" (Black) :

• "Remote switch cover" (Black)

• "Original switch cover"

• "Lever arm support"

"Moving parts" (Orange) :

• "Switch button" (Orange)

• "Remote switch bar" (Orange)

• "Original switch bar"

• "Original switch lever"

• "Lever arm" 

• "Crossbar"

And 1 folder that contains each piece separately WHITHOUT support. 

Equipment

All you need is:

• a black BIC pen to color a section black

• a T10 Torx key (included with the printer)

• a few centimeters of filament

• a pair of pliers to cut it

Colors

I recommend using Black for the stationary parts and Prusa Orange for the moving parts.

But of course, you can change the colors of the pieces.

For example you can print everything in black except for "Switch button" and "Remote switch bar" parts, which are orange

But the parts with their color listed in parentheses (e.g. : “Orange”) are very visible (on the front). So keep this in mind if you want to change their colors.

Updates

-  26/06/2026 : Modification of the “Lever arm support” for a more secure fit

Happy printing !!
