Cleaning.

I'm a moron, and I don't know what to use to clean which material. I have already made some metals and tv remotes have color washed away from all the aclohol I'm using while i wipe them down. I know I can't use bleach on any fabric, but I can't use it on practically anything except tiles and ceramic. Plastic is everywhere, sometimes it seems like alcohol can be used on them, sometimes it seems like it's to strong.

How the hell do I clean my house, what do I use, how do I use them, what is safe to use on which material, and how do I not inhale bleach and aclohol vapors all day when I use them to clean?

This is all related to basic cleaning and disinfecting the 2019 coronavirus, of course.

Is there a way to refresh these at home? It's time to get innovative.

I have a couple sets of these but due to current events they are difficult to obtain. I want to use them for oil based paint. They still block solvent odors so the carbon filters are still good, but because I also put on the respirator for sanding I think the particulate filter portion got too clogged over time and they take a good amount of effort to breathe through. Any ideas?

So I hear the US has less than 200k ventilators. in the case that you are in a rural area and cannot access a ventilator in the eventual event that manufacture cannot keep up with the sick. Do y'all have ideas for it to work? Schematics?

The MIT route is probably the best in the short term since it uses readily avaible supplies, ie small motors and ambu-bags. True ventilators are precision machines able to tune and read inspiratory and expiratory volume as well as pressure and make on the fly adjustments while adding oxygen, heat, and humidity through filter media.

In true emergencies, we'll probably be hand-bagging people.

I'm looking for a high quality multipurpose acrylic paint. It will not be used for different kinds of craft works and not for canvas painting. The first things I will use it for is painting a bottle and to dye a cotton string and I will probably use it on wood too and maybe leather.

Can I do all that with one type of paint? I'm looking for something high quality with good and lasting colors. I will only use it occationally, so small bottles is better than big.

I have been looking at liquitex, but it is mostly for canvas painting and I read it's not that great painting. It's just too much info out there for a no-painter like me to navigate. Please help. I'm building a lamp

I need to construct a deer fence for the garden this year on a tight budget. I have ordered deer fencing that is 7' high and 100' in length. Due to it's light weight I figure I may want to set posts every 4-6'. I am thinking about getting these pvc pipes as the fence posts. They are 10', so I can bury them 3' to match the height of the fencing. This is really my cheapest and easiest option but I have to ask, is it fucking retarded? Will this not work?

I want to /diy/ a bag that attaches to a bike rack. I'm willing to modify and even to make a bike rack myself if a special design is needed. The objective is to make a bag that attaches quickly to the rack without wasting any time. So I would be doing both, the rack and the bag so I can design them to work together.

There are multiple bike racks and all kinds of different bags on the market but all of them share one fatal flaw: their attachment systems suck and are usually strap based, This is totally time inefficient and frustrating when you need to put or to take your bag quickly.

My solution to this problem is to produce a bag and rack that are designed around a superior attachment system.

Now, my questions is: what type of attachment system should I use to create this project? I don't know anything about attachment systems.

I have two ideas that may work:
-The bag has magnets on the bottom. The rack has magnets on itself. The attraction force should be sufficient enough to hold the bag in place.
-The bag has a rail on the bottom. The rack has a rail on itself. The user pairs the ends of the rails and slides the bag till it locks in place. (similar to the telescopic rail that drawers have).

to be exact the casters would need to be added to a: 3/4 to 1/2 reducer or the option would be to remove the reducer and attach the casters to a 3/4 elbow.

The problem is other than finding a 1/2 or 3/4 expanding caster with threading, I don't know how else to attach it.

The secret for flex is to get fucking slow. I mean 15mm/s.
TPU needs more longer time to liquefy in the hotend compared to other filaments.
You also need to crank up the flow/extrusion rate to ~120% because the extruder teeth grip a lot deeper and the feeding gear diameter is reduced. Otherwise you will underextrude. I'm also coasting at 0.4mm3.
As soon as I considered these points I got very good results.
I'm printing TPU with retraction turned off, I should give it a try though. Stringing is quite hefty.
