PETg orange, Kilo spools are currently £7.59 on Amazon! Orange Petg £7.59

PLA can be painted.
B&m sell a good aerosol primer, made by "turner and gray", then the Range do a range of acrylic paints by "art studio" which are £1 a bottle.

Prime.
Paint with metallic gold.(NOT brass! It's too red).
Then a "wash" of watered down black.(with a bit of green in maybe?)

Or: there's a product called "rub n buff" - I've never used it, but it's well regarded in the 3dprint painting groups I frequent.

This paint looks good

On the back of my newfound litter picking hobby, fire up the printer!

Grabber by mathiaspl20

Grabber to attach to 15 or 10mm OD pipe / Aluminium extrusion. The pivot holes are sized for 2.5 mm pins / m2.5 screws, theholes for the pins for the spring are 2mm. The spring needs to extend to about 45mm at the maximum travel.

You want to glue some rubber to the inside of the arms, if you use that.

You'd be better of just buying one. They take some fair old stick, when you're picking the likes of glass bottles & such up.

Buy???

Tool late, watch this space in about 3 hours!

Yes, it'll get TPU end caps on the pickers probably.

It says it's for a 15mm tube, got to be a length of copper to start with.

The big problem is there is no handle with the design. In the foreground is a bung. I'm presuming that just caps the tube and the string comes through and gets tied in a loop.

Thus I need to come up with a pistol grip? Going to cheat I think and pinch an older relative's picker and plagiarise that design! Measure it up, adapt to suit and print!

Thinking something like the Barnett catapult wrist brace.

It'll be over complicated whatever!

This is the type I use, if it gives you any inspiration.

Yeah, but my one has GEARS!

I designed a replacement crevice tool for Henry. An overnight print fell over despite brims etc and I ended up with a very pretty coil of fine filament. I suspect that the Micro Swiss extruder also jammed against the top rail because it is now more bulky than the Bowden extruder.
The print has now been restarted horizontally with supports, in the hope that it might finish. It will be another overnighter though, so I will have to cross fingers.

I meant for the handle side of things!

Oh I see!

Right then, been and got one like @MattF 's to copy / play with.

Just laid the real picker on the scanner then dragged the jpeg into AutoCAD:

& off we trace!

Don't forget you want a bag hoop too.

Is that the yellow bit?

Whoops! The STL came with options for a 10 or 15mm dia rod, we printed the 10mm one. Luckily the pincer gear is common so only need to reprint one piece.

Currently working up the handle detail. I did the basis in AutoCAD, my lad tweaked the STL and is now chequering the grip.

Using tree supports which are weird...grey PETG:

A pretty render of our MK1 handle design. This for 15mm tube.

I've left No.1 son printing it and gone to bed.

Nope. A hand held hoop, for holding your bag open. Saves a lot of fannying around battling with the bag.

 

[Onoff]

The MK1 handle is printed and the 15mm pipe is a lovely transition fit. Likely a tad loose but PETG is inherently a bit hairy I find, so that helps with grip. The holes in the grip will make it a doddle to drill through the copper and fit some roll pins to hold it together. I might even just use split pins so I can field strip it with just a Leatherman...



Really happy with the chequering effect my lad managed on the grip.



However...

The ergonomics leave a bit to be desired. I have really big hands so should really scale this up a bit. I think it looks a bit lost:



If I extend the copper out the back, up to a wrist brace, then it pushes into the flesh between thumb and forefinger. I wonder if that will rub and / or leave me with a green mark? It needs to be perfect so it's the envy of other trash pickers like an Ulfbehrt sword...



Options are to make the grip bigger, lessen the grip angle maybe or raise the tube higher. As I designed the grip by laying a real trash picker on a flatbed scanner and tracing round the image in AutoCAD I'm happy for a first go.

I'll work with it for now.

Trigger mechanism next and figure how I'll slit the underside of the copper and get everything in. Not so easy with tube as with the original box section. Still, keeps the grey matter ticking over!

Got to go look at SWMBOs car for a bit now so playtime will have to wait.

High speed litter picking?
