This model was created using the XY joint model included in BootyCall jones' K1 "Flanged Bearing Gantry Project" and Henlor's "Creality K1 CAD Model".

One of the pulleys used in the XY joint has been replaced with a geared one, so some dimensions may be slightly different.
The changed idler is  13mm 16t idler .

The assembly method is generally as described in the installation manual of the "Flanged Bearing Gantry Project", but use a toothed pulley only where the teeth of the timing belt of the XY joint contact the pulley.

When installing the carriage, use M3 heat insert nuts with an outside diameter of 4.2 mm and a length of 6 mm and M2 heat insert nuts with an outside diameter of 3.2 mm and a length of 4 mm.

Although the XY joint and carriage have been modified to avoid the use of imo screws, a total of six additional M3x8mm countersunk screws are required to secure the linear rail.

The linear rail used is MGN12H, 320mm.

I am sorry that I could not create a manual for this model since I originally made it only for my own use.

Please try using it if you like!
