Bed handle for Ender 3 S1 and S1 Pro with ADXL345 mounting holes

The design of the original handle by @Lucas_972053 is nice and simple, but I wanted to add mounting holes for the ADXL345 sensor. 

Model details

As with the original model:

• Print in PETG (or other heat-resistant material) to avoid warping due to the heated bed.
• Use M3x6 screws for mounting the handle to the bed. You should have some spare ones that came with the printer.
  • Caution: using longer screws could damage your heated bed!
• I added a version that has the same width (at the screw locations) as the handle that comes with the Ender 3 S1 Pro, for use with the screws that are installed to fasten the included bed handle (M3x8).
  • Some minor changes were made to the geometry.

To mount the ADXL345, I used a pair of M3x10 screws and M3 nuts. The holes are wider than the screw, so you might want to apply some pressure to get it square (though I doubt having the sensor slightly off would impact the measurements).

Should work fine on both Ender 3 S1 (@Lucas_972053's presumably was installed on an Ender 3 S1) and S1 Pro (my printer model).

I also added a chamfer to the bottom face of the print to help with elephant's foot.

My Klipper printer.cfg section for the bed, as mounted in the image:

Printing details

• PETG
• 0.3mm height for first layer
• 0.15mm height for other layers
• 4 perimeters
• 4 bottom/top layers
• 15% infill (gyroid pattern)

1. Added holes for mounting an ADXL345 on the handle.
2. Chamfered the base of the print.
3. Added a version that works with the bed handle screws that come with the Ender 3 S1 Pro.
