Perimeters PLA

--> optimal perimeters for vertical shells (x,y)

1 --> 0.80 mm
2 --> 1.64 mm
3 --> 2.48 mm
4 --> 3.32 mm

--> optimal perimeters for horizontal shells (z)

multiple of 0.2 mm (=layer hight)

Perimeters ABS

1 --> 0.76 mm
2 --> 1.51 mm
3 --> 2.23 mm
4 --> 2.94 mm

--> optimal perimeters for horizontal shells (z)

multiple of 0.2 mm (=layer hight)

Heat insert

d_m3_heat_inset = 4.6 mm
d_m3_heat_inset_CAD = 4.6 - 0.2 mm (4.4 mm)
l_m3_heat_inset --> 5.7 mm (3d jake heat inset)

d_m4_heat_inset = 6.3 mm
d_m4_heat_inset_CAD = 6.3 - 0.2 mm (6.1 mm)
l_m4_heat_inset --> 6.4 mm (3d jake heat inset)

M3 SHCS screw

d_head --> 5.5 mm
l_head --> 3.0 mm

M4 SHCS screw

d_head --> 6.85 mm
l_head --> 3.9 mm

M3 Nut

d_m3_nut = 5.3 mm
d_m3_nut_CAD = 5.3 mm + 0.7 mm
t_m3_nut = 2.2 mm
t_m3_nut_CAD = 2.2 + 0.2 mm

M4 Nut

d_m4_nut = 6.4 mm
d_m4_nut_CAD = 6.4 mm + 0.7 mm
t_m4_nut = 3.1 mm
t_m4_nut_CAD = 3.1 + 0.2 mm

M5 Nut

Font for 3d printing (Autodesk Inventor)

Arial Rounded MT Bold
size = 5 mm

Changing colours with M600

Pause gcode is applied before the layer starts.
Set pause if you see the first layer of the structure

Hole setting

d_outer_target + 0.3mm = d_outer_CAD
