These are Overture Super PLA+ in green, my previous forks were printed in eSun PLA-ST, with near identical settings
- Printer: Prusa XL, 0.4mm nozzle (Only single colour though, I could get several colours and do a more interesting version). I used the Prusa XL because these things are too big for a standard-sized printer
- Layers: 0.2mm
- Top and bottom: 5 and 4 layers respectively (why not the same? I don’t remember, or maybe I just made a mistake)
- Perimeters: 6 (typically default is 2 or 3)
- Infill: only 10%
- Modifier: I created a modifier slab which added a few more solid layers in the centre of the part
They weigh about 140g each and it was about a 6 hour print (the XL is not the fastest on its default settings)
Hopefully these settings will make it strong enough, I did the same thing last time with grey ST and they suffered only minor dents and scratches (and some cosmetic abrasion from Sandy Cheeks) .
They are each bolted on using a pair of M6 bolts going into reverse mounted insert nuts in the HDPE arm. There is a cross-brace piece for extra rigidity with a machined nylon spacer (not 3d printed) just because I could.
Note to those new to 3d printing structural parts: infill is not very structural. You will get a lot more strength for the weight with perimeters (x/y surfaces) and top/bottom (z surfaces). Infill is basically a mish-mash of strings which supports the top layers, In some cases it’s possible to use 0% infill, I could probably have done that here and it would be almost the same.
