Made a hopper and chute for our wheat grinder. The integral hopper is really small and empties in about 10 minutes. The new one goes for about 40, which is awesome. What’s not awesome is I need to redo the chute coming off the bottom of the grinder. It backs up with flour and doesn’t go down, so it just starts spilling over the sides. I think I just need to make the opening larger.

Or have it more vertical.

Not to be Debbie Downer. But is that Food safe filament and a food safe hot end? I was printing some stuff that needed both a few years ago. I found food safe filament from a Canadian company and I bought steel nozzles to handle concerns about brass constituency

nozzles were from Amazon I believe. Filament was from Filaments.ca a Canadian company. It’s been a few years so I have no idea if either are still available but I wanted to point out there are such a thing or there were.

Great point - my understanding is that the food safe aspect of 3D printing isn't so much a function of the material, but rather that the layer lines can trap/grow bacteria with wet/liquid foods. With this being a temporary contact point for flour and wheat berries (which are dry) there shouldn't be much that will happen by way of trapped bacteria in the layer lines. That being said, the green parts are PETG and the black/blue parts are PLA. As for my hotend, who knows. It's a Bambu hardened nozzle, but I'm sure there's other stuff in the hotend that contacts the filament.

It most likely is an angle issue, but you can verify by comparing to the angle of repose for your material...


If it is, you could try shimming the mill up with spacers or notching the base plate board where the chute is in order to gain clearance for a steeper chute.

Without a doubt, steeper is better. Orienting the print so the layers were in line with the direction of travel would reduce friction as well.

@Jeff Those flies are awesome. They even have little eyes. Care to share the stl? What are they doing in that case?
My best bud retired to Maine and asked if I could make flies. I found a file, printed, then painted with metallic. They will be adding the hooks up there. My only regret is that I can't visit and enjoy some of those trout. The box is just a cool touch.

STL as requested:

Maybe I'm being dense, but it looks like I have to install Bambu Studio, open the print profile, and export it as an .stl in order to get the .stl. What the heck? Seems overly weird. I just got my 0.25mm nozzle and would love to try this, but I'm not going through all that. :headscrat

Edit: Found what appears to be an .stl of the same fly:

If you download the .3mf file you can should be able to export the .stl without issue. I just tried it on that file in PrusaSlicer and it works....I assume any slicer that can open .3mf's can do the same. Or you can just download the .3mf into your choice of slicer program and print directly from there, most of the modern ones out there should support the format. The Import/Open in Bambu Slicer button on Makerworld is just downloading the .3mf file and then auto-opening it in Bambu Studio

Here's mine. Prusa MK3S+, 0.25mm nozzle, 0.05mm layer height, PLA. Printed flat with no supports. I had to put a hand lens in front of my phone to get a decent pic.

Edit - I have no idea what size these are supposed to be. The stl was huge, so I scaled it down until the legs were two extrusions wide.
The fly looks like you powdered it or is that the PLA?

working on spool holders for 10kg spools. the cheapest way I can figure to get this done:

C channel with a 3/8" thru hole. self tapered to the racking rail. bend 3/8" rod to hang. once inserted a quick tack to keep the rod from coming out of the C channel. when reload is needed it pivots out to allow access. then hangs.

bend up on end to capture spool.

scales up to 20 per rack

thats the wire bend: same plane. nothing fancy. table bender will work fine to make them:

laser cut/bent bracket mount. self tapper into the cross beam. lock it into place with a collar. slots to level it off with all the flex in things.

My latest creation: The Bambu AMS Hexagon Storage Wall (HSW) Wall Mount!

I have 3 AMS units so I liked the idea of combining the convenience of wall mounting the AMS units with the modularity of HSW. This way I can hang tools and storage in the same place. There is an existing model from another person, but it has many errors in the file as well as MILLIONS of triangles in the STLs. My model is under 15,000 triangles per side. I will soon design a few accessories for it like a plate rack
