Lymow One: Tấm chắn phía sau bộ phận cắt

Description

One of the most frustrating issues with the Lymow One is its unreliable charging, which is often caused by dirt accumulating on the charging terminals during operation.

To avoid this grass and dirt coming from the cutting deck, I increased the height of the rear cover. It now extends 5mm further downward compared to the original part. But as I do not use a cutting height below 40mm, it is still high enough not to block the mower in his movements.

Printing

Printing of the rear cover is not trivial: It needs 2 different materials - flex and non-flex:

The model consists of 2 parts to be printed with different materials. To get a strong connection, both materials partially are printed on the same layer.

This means, you need a printer with

• a print plate of 330mm

• at least 2 hot ends.

  • stiff part: PETG

  • flexible part: TPU

I used the Prusa XL for this print.

In the slicer, ensure the correct position of the 2 parts of the model:

Nut Plates

Printing of the nut plates is quite easy.

• Filament: PETG, ASA, ABS or similar

• Infill: 100%

• Layer: 0.25mm

• Ironing: on

• Support: not needed (print the plates with nut opening on the top)

Assembly

Cover can be mounted with

• 2x screw M4x10mm

• 2x nut M4

The nut plates help you to avoid turning of the nut and filling the gap to prevent dirt from accumulating:
