Electric adjustable cutting height box

[raess]

Hi,
So I design a concept of a Electric adjustable cutting height box.
stroke length 0-50mm

Using a vl6180x or similar to keep track of height.

Parts:
1x Step motor 28BYJ-48 with drive card ULN2003
1 x Rubber 82mm x 85mm x 1.5mm Seal Ring
1 x 8mm x 80mm Threaded Rod
1 x 57mm Integrated brushless motor 50W 24V 3000rpm
3 x JFM-0507-05
3 x 5mm x 82mm shaft

M2 Thread Knurled Insert
M3 Thread Knurled Insert
M5 Thread Knurled Insert
8mm bearing

First Enormous Congratulation for the 3D creation .
Can you tell me more on the screw insert, there looking perfect ,Where is it possible to order and how did you fix them (I suppose with solder iron).
Is it PETG? The motor maybe heat a little Inside the box ,so a Thermal sensor can integrate the electronics parts.
Need to be integrate in the 3D platform.

1. I order my screw inserts from here: https://www.bondtech.se/sv/produkt/gang-insats/ (Always order from here since they keep high quality). I guess you can find some on aliexpress (but i am not sure of the quality.)
2. I fix them with a solder iron. Just makes the hole very tight. heat it with solder iron until i can press it in.
3. The filament is this Alloy 910 https://taulman3d.com/910-features.html
