Workshop Uses for 3D Printing

[Dr.Al]

The 3D printer has been in full bandsaw mode for the last few days.

The latest is a Maskery pattern dust extractor:

(45.33 KiB)

and yes, I could have made it out of 40 mm pipe and brackets, but that would have involved going to a shop, and where's the fun in that?

The three brackets each have two very strong 20 mm diameter, 6 mm deep magnets glued into the back face (which is curved to match the shape of the door: a 1.5 metre radius curve!)

The bottom piece (printed in black) is shaped at the end to match all the other bits and pieces in my garage (actually based on the outside diameter of the tools that came with vacuum cleaner, so I can still use those without disconnecting the dust box).

Close-up of the top bit to show how it works for those too lazy to watch Steve's video (the sawdust you can see on the underside of the table was there before I fitted the dust catcher):

(33.86 KiB)

I was far too lazy to do as thorough a test as Steve did in his video, but I thought it was worth resawing a bit of 150 mm poplar in half and seeing what happened:

(46.05 KiB)

Not perfect, but pretty darn good:

(44.62 KiB)

I'm not sure it's really necessary...

Not stopped you before

…..but I do agree, solution looking for a problem.

Some sleeves to go over some of my T-handle hex keys to make them the same colour (ish) as my other T-handle hex keys so I can see at a glance which is which.

(84.12 KiB)

The sleeves do mean that the hex keys won't go down into tiny deep holes (e.g. those with grub screws in), but those are few and far between and I've got a couple of other sets of t-handle hex keys anyway!

I've coded some of my allen keys using wiring sleeves and the international resistor colour code which is burned into my brain since childhood experimentation with electronics. Leads to an instant association of a colour with digits 0-9

eg orange, orange, red for 3/32" brown,grey for 1/8" green orange red for 5/32" etc

works ok until oil gets to the rubber and the sleeves perish.

That's an interesting idea for a colour scheme: like you I have spent a lot of time looking at (and interpreting) resistor colour codes. I'd wondered about using heatshrink as a colour code, but when you want to have specific colours (to match the specific colours of my coloured hex keys), it can be quite hard to find.

I've long forgotten the ancient body, dot tip coding scheme when most resistors were carbon rods an inch or more long and the traffic light dots on capacitors. - see how ancient I am!
It's impressive how they fit all the ohms into modern micro-miniature resistors that are even too small to have colour coding and I need a microscope to read the numbers!

You're obviously using big resistors if they've got numbers on them

The numbers are usually printed on 0603 (1.6 × 0.8 mm) package sizes and above. Where I work we use a lot of 0201 resistors & are looking at 01005 ones for some future stuff. 01005 resistors are 0.4 × 0.2 mm Not much room for numbers on them!

I'm only doing simple stuff for my own hobby projects and stick to NK3 resistors with leads on em. Iv'e possibly got a "rest of life" stock of these in E12 values.
Most stuff is knocked up on vero board or RF bits on copped clad FR4. I stay away from SMD passive components on ease of use grounds with limited tooling and only a fine tip weller iron. Suits my level of work these days.
Apologies for thread hijack!
