Description

Need more visor frames faster?

The Visor V-Frame prints in 19 minutes with a 0.6mm nozzle.

This frame is quite a bit thinner than the original one, but the V-shaped profile makes it just as rigid!

There are also stacked versions of the Visor V-Frame with an 0.25mm Airgap between the parts. Obviously, the bottom sides won't be super beautiful, but that's okay, I guess. (see picture)

ATTENTION!

NEW VERSION OF VISOR V-FRAME IS NOW COMPATIBLE WITH ISO-838 4-HOLE-EXTENSION! (The old version used the A6-mark on the punch. Sorry...) So please download the new files and set your punch to "3x8" or "888"!

To get the best results, it is important to use the following

Slicer settings:

Print Speed: 50mm/s  
Layer Height: 0.25mm  (important for stack production!)
Top/Bottom Thickness: 0  
Infill Density: 0  
Wall Thickness: 1.2mm  
Flow: 105-115% (find the sweet spot where parts are stable, but split apart easily) 
Support: Off  
Combing: All  

Additional tweaks:

Build Plate Adhesion: Skirt (risky! try to avoid brim in mass production...)
Print Fans: 50-70% (don't risk shrinking!)
Bed Temp: about 10°C higher than normal, ~70°C for PLA

Materials and methods

1 Frame = 11g

Successful tests in PETG and PLA, where PLA is substantially stiffer, but both will do the job.

Splitting stacked parts with a blade should be very easy (tested in PETG and PLA). If not, reduce Flow and/or Print Temperature. Please be careful, don't hurt yourself.

If you have a 0.4mm Nozzle, it will print in about 30 minutes. If you have a 0.5mm nozzle, consider tricking your slicer into thinking it would be 0.6mm. It should work just fine.

@exlink Hi there! Well, that depends on your nozzle. The thickness of the frame is 2.4mm.

So, if you have a 0.4mm nozzle, you need "wall line count" = 3 for a 100% filled part.

If you have a 0.6mm nozzle, you only need "wall line count" = 2, since the inner walls will then already touch each other, fusing into a solid piece.

If you have a 0.5 mm nozzle, it would be best to pretend it to be 0.6 mm in your slicer software. It will be fine. Maybe turn up the print temperature a little bit to compensate for the 20% higher extrusion pressure.

!!!!! No need for top/bottom layers or infill !!!!!

Since the part is designed to be printed by a nozzle that just goes round and round again, you only need enough wall lines. Saves you precious time and the stacked parts separate easier after overnight production.

I wish you good luck with the production!

Hi, what do you put in "Wall line count", "top surface skin layers", top layers" and "bottom layers"

And do you activated "thin walls" ?

Big thank !
