General Information
This file is designed to mate with the Creativity Dual Y-axis linear rail kit for MGN-12-H rail/carriage kit.

Creativity Upgrade Y axis Linear Rail Guide Kit MGN12H 300MM Length for Ender3 V2/Ender3 Pro 3D Printer(Linear Rail NOT Included)
They are simple mgn12h carriage to Ender 3 Pro y-axis POM wheel axle bolt adapters. Made of anodized aluminum; cheap and effective. I would not recommend buying the kit that comes with rails; they are of poor quality.
This part is designed to mount to the central M3 bolt hole in the adapter.
--------------------------------------------------------------------------------------------------------------------------------
Motivations
This part was designed due to the lack of an STL or CAD file required for modification or replication of the included 3D-printed part used to activate the y-axis endstop. The part provided is too short for the regular 300mm rails commonly used for y-axis conversions.
Therefore, I decided to take measurements with a caliper and rebuild the part with modifiable geometry using equations in SolidWorks.
--------------------------------------------------------------------------------------------------------------------------------
Remixing and Modifications
I have included all the SolidWorks files required to create the file. The models are dimensionally constrained and fully parametric. Feel free to change any values in the equations tab to suit your needs.
(The geometry isn't fully parametrically constrained; therefore, you may need to modify additional values if you change a singular value.)
If you do not have SolidWorks, I highly recommend OnShape. It is a great alternative with a more modern, Github-like, version control system.
Parameters of Concern in SolidWorks File (Yaxis-EndstopTrigger-Mod.sldprt):
- YaxisTrigger_mod-AdditionalLength
- Change this value to whatever value you need to cover the additional distance required to activate the y-endstop.

Print and Assembly
Print Settings:
| Parameter Name | Value |
|---|---|
| Material | ABS |
| Speed | 200 mm/s |
| Cooling | 0% fan speed |
| Nozzle Diameter | 0.4 mm |
| Line Width | 0.45 mm |
| Layer Height | 0.2 mm |
| Walls | 4 |
| Top layers | 5 |
| Bottom layers | 5 |
| Infill | 40% isotropic (gyroid used) |
This is a functional part, therefore high-strength settings have been used (5 top and bottom shell layers, 4 walls, 40% infill (isotropic).
Recommended Print Materials:
ABS, PETG, NYLON, etc.
I recommend using plastics with high glass transition temperatures, as this part is located next to the heated bed and can warp as a result.

Post-Printing and Assembly
Assembly Materials:
- 1x M3x8 Bolt
- 2x M3 washers
The M3 bolt and washers are used to clamp the part to the central hole in the adapter.
