Well, this is old news. This came out last month.

Oh, you want a classroom lesson. After the kill you have one of two choices. You can either cut up the animal and carry it home in pieces, making multiple trips to do so if alone. Or you can process the animal on the spot. Taking a few days to do so.

If you are persistence hunting, you are almost always hunting in a pack. And everyone can carry something back to the camp. Remember: Not everything is going to be brought back. A moose will dress out maybe at 50% at best. And you leave what you can’t carry or don’t want behind. Modern hunters often do similar today. If I can’t get a pickup or 4 wheeler to the spot, I field dress the deer and cut it into quarters and make a couple of trips to carry the meat out. A 200lbs deer will yield about 90lbs of edible meat-- give or take. Easily carried out by one person in 2 trips.

Or you can process the carcass on the spot. It was a common hunting technique in the North Americas to run a herd of animals like bison off a cliff to kill or cripple them. It might take a day or two to set things up, but as the hunt began and the herd was funneled to the cliff, the rest of the group, those that weren’t able to actively participate in the hunt, would follow at a distance behind the hunters. When the herd was run off the cliff, everyone would set up camp right by the kill area and simply eat and process as much as they wanted for later. Again, leaving behind what they couldn’t process or want.

All this information is available by a simple search if you want to know more. A method I highly encourage everyone to use to gain knowledge.

Meh, zombie infestations are easily prevented by simply the shoe laces together of the dead. Thus preventing them from even walking.

Moose hunters just shoot them these days. The only time anyone is running any more is when they are headed to a charger for their phone because the charge is down to 10%

I’ve seen hydraulic cylinders up to a mere 150 tons, but they both used vee threads. But those cylinders can had far,far bigger than that. That would be a very good application of buttress threads. Much like the balls screws on a punch press. Lots of force in one direction.

Surgery is not required. You only need to 5% smater than the tool you are using.

A properly fitted straight bladed screw driver will fit snugly in the slot along it’s entire length. This offers more than the ‘two points of contact’ that your poorly chosen screw driver does. Add a hollow ground blade, they get an amazingly powerful grip. Learn to fit a screw driver properly and you will seldom have a problem with a slotted screw. As toolmakers and high end gunsmiths know and you don’t.

Of course, if you have neither the skill or enough ambition to be bothered to ensure the tool fits the fasteners correctly, you probably should choose a more foolproof tool and fastener.

At that diameter, I would probably recommend a bottle cap thread. It’s a rounded profile that is easy to print.

Never, ever, ever do more effort than is required.

Under Quality – Layer Height – First Layer Height. Adjust the layer height as needed. Generally speaking, your first layer should be no less than half the nozzle diameter. So, a .40mm nozzle first layer height should be .20mm. Thought for larger beds, you may wish to increase the first layer height a bit to help with bed adhesion over a wide area.

My first inclination is to got to Quality – Walls and surfaces – Avoid Crossing walls and check that box. See what happens when you print your Benchy.

If you still have issues, go to you filament settings for the filament you are printing with, (the little pencil to the right of the filament box), make sure you have the Advanced slider on, click on the Settings Overrides tab and check the Length, Z-hop height, On surfaces, (select All Surfaces in the drop down box to the right), Retraction speed, (the default is fine), the De-retraction speed, (set to zero), Travel Distance threshold, Retract on layer change, Wipe while retracting, and wipe distance.

This is a start.

Having single pointed 3"-4 Buttress threads on a manual lathe for punch presses more than once and hand grinding the tool bit from 1/2" x 1" HSS, I still have some PTSD over that thread form. But hey, if you are looking to make breaching for a 16" Navel Rifle, it’s really the only game in town…

As a toolmaker, I have seen Buttress threads used in only 3 places. Large artillery breaching, punch press ball screws, and VERY high end, (read expensive), machinist clamps. I own a pair I picked up at an auction 30 years ago in a bucket of “junk”. I think they were made by another machinist for personal use.

Edit to add: Buttress threads are directional. They can be either left or right. The choice being totally dependent the direction of the force applied to the threads. The perpendicular edge is the strong part. And the direction must always be called out.

Meh, slotted screws get used a lot. What most people don’t get is the reason they have problems with slotted screw heads is because they don’t use a proper fitted driver that fits the slot correctly. You always try to use an undersized driver and are then shocked to discover you have problems.

Don’t blame the tool for your poor choices. Use the properly fitted tool for the job.

Number series machine screws get their designations from wire gage sizes that they were made from. Which traces back to several different British thread systems waaayyy back in the day. While there is no hard and fast rule, the number series screws are sometimes referred to as ‘Machine screws’ while fractional series fasteners are referred to as ‘Bolts’. No one knows why, and Whitworth is dead. (Toolmaker humor).

All actual diameters of screws are a bit under nominal for external and a bit over size nominal for internal. This is the clearance needed to make a screw and nut fit together. This all applies to metric thread fasteners also. Thread fit classes are a story for another day.

I have used rpms, AppImages, Flatpaks, and source. I have even used a snap or two when I had no other choice.

If you can’t work with them all, can you even say you Linux Bro?

My pie chart of blame looks more like 90%/10%. Where if I simply set something down, even with the need to use it immediately, I lose it.

I rely heavily on my Wife to find things for me. Without her, I would lose my head.

A custom vee thread screw and nut, as you have done, is easily done in the Thread Profile workbench. As a workbench, I don’t think it’s all that popular, at least it’s not going to be as popular as the Fasteners workbench.

Other than creating the head of the screw and the shape of your nut as a separate sketch and pad, you can simply fill a couple of boxes with your own numbers, click the helix button, then click the Additive Loft button, both provided in the workbench toolbar, wait for the threads to generate, and it’s done. And it’s parametric.

I recommend checking it out if you’re using FreeCAD.

Prusa Core One with MMU or Qidi Plus 4 and the Qidi Box. The Qidi Box is at the pre-sale point now. They have been taking things slow with their AMS unit. Either printer is affordable and in the size range you want. Both are corexy, Qidi run Klipper and Prusa runs Marlin firmware. Both brands have heated enclosures to make printing fussier filaments easier. And PETG definitely benefits from that.

If I was starting over and wanted a larger printer, it would be a coin flip choice between those 2 printers.

I got caught the same way with an impulse buy of an A1 Mini/AMS Lite last fall. I’m still running the 1.04 firmware and Orca Slicer on LAN mode for several months now with little issue, (sometimes it drops the LAN connection on start up and needs to be manually reconnected). If you do upgrade to the evil firmware and don’t like it, Bambu currently does let you downgrade to an older firmware and you can go back to a safer firmware.

Most of the Bambu users I have interacted with don’t care because they want to run their printer from the Bambu Handy app. And if you want to use the Handy app, you can’t use LAN mode because you need to be logged in. But I don’t like using my phone for such things anyway.

That ain’t science. It’s engineering doing what marketing asked for.
