Measured internal diameter of light pole mount, subtracted 0.5mm
v1
Generated negative volumes in TinkerCAD to represent the monitor arm
Covered in a large rectangular prism
Designated this the base of the two parts
Added holed-cube for placement of pole part
Printed the base with
4mm nozzle
0.3mm layer height
20% gyroid infill
Printed on longest side
Added internal support enforcers
4 vertical walls
Left print overnight (~5hrs print time)
Had a hard time removing supports
Base
Fitted perfectly
Quite heavy
Pole location meant when light is tilted it touched the wall
Needed redesign
v2
Back to TinkerCAD
Reduced all walls of base to 3mm width
Moved pole socket to front
Intersected base of pole socket with top of monitor arm negative space to make an orifice (save some filament)
Printed
0.6mm nozzle
0.4mm layer height
4 vertical walls
20% gyroid infill
Base V2
Fitted perfectly as last time
Had the pole socket lower by 7mm
Plenty strong enough
Pole V1
Loose fit to base v1
Good enough fit to base v2
Adjusted pole height for pole socket offset as a result of base V2 changes
Adjusted pole square base to same dimensions as pole socket
Reprinted pole
0.6mm nozzle warped edges a bit
Reprinted pole didn’t fit in base v2 due to being too big
Reverted pole v2 to same square end dimensions as v1, which had fitted fine
Reprinted
It worked
Reflections
3mm thick walls is sufficient for strong PLA parts
5mm thick walls results in a lot of infill, adds a lot of time, and doesn’t seem to add much strength, or at least isn’t worth the extra strength
Internal supports are a pain to get out because removal meant pulling the rectilinear parts which didn’t in turn pull off the interface layers very neatly
It was overkill to initially print v1 on its widest side as v2 printed upside down was strong enough not to break
