I have a big UV light that's within the right wavelength and just aim it at my print for a bit at different angles, but I have considered building or buying a little rotating base.

Honestly I just keep my IPA in a Tupperware container, close the lid and slosh the part around and then do finer details with a toothbrush to get everything.

I mainly use elegoo, I particularly like their ABS like. I did it in the clear green because that's what was in the vat and I am lazy >.>

I'll probably make the changes tonight after work and upload a mk3

If you can solder, you can easily build a turntable for under $20.
This video used a cheap lazy susan from Amazon with an N20-size motor hot glued to the bottom. The motor shaft is keyed, so I printed a wheel to fit the shaft and put a 1” rubber band on the wheel for friction. The motor speed is controlled by a cheap pwm controller and powered with an 18650 battery I had lying around.

Got distracted after I got home, finally sat down at the computer. I have added a hole embedded in the groove, so now you can tie a retention cord or run it though the hole with a knot on the end. If you want to be especially fancy I guess you can do both and braid them?

Quick update: with my current setup they print on FDM in about an hour and ten minutes, but it's rough (.3 layer height with .6 nozzle). Running a cord around the groove and doing a three strand braid with the knotted center looks very snazzy.

Nice, I'm still looking for broom handles for a couple other projects.
Not as easy to getb hold of as you'd think.

My theory with lining a box with aluminium foil is that it reflects uv light (probably) and thus even with a top mounted light, you should get really even exposure all round the model without any rotation needed.
Round the corners out and it should work even better.

I am surprised that cheapo broomsticks aren't available at poundland (if you have one in your area, I don't know how widespread it is there) or something akin to it.

I think I have seen people use those LED strip uv lights to make cure boxes, it's definitely worth looking into.

Also: Thank you Rat man!

poundland, home bargains, indian hardware shop (who usually has everything) poundstretcher - no 'just broom handles'.
Weird, I'd have sowrn they all used to sell them.

I'm putting off going to b&q as the handles will cost more than the brooms from anyone else.
But I hate buying something just to throw the expensive bit away Sad

Haven't looked on amazon yet.....

Well, could have got 10x4ft by 23mm on amazon for £18
1 for £6

But ended up buying 20x from ebay for the same £18.
Unthreaded.
I mean that's what glue and screws are for

I know it sounds like a lot of broom handles - but it's a remarkable useful size and shape bit of wood.
And I genuinely need a new handle for the snow shovel.

Plus the other project could end up using quite a lot of extra handles

And, as they say in ireland: 'a bargain is a bargain, begorrah !'

And at less than a pound a stick - figure it's worth stocking up

Probably won't get them till after christmas.

A collapsible/foldaway/sectional staff sling.
Would seem pretty easy.

When I get my sticks I'll make one

But as I don't want a threaded end, and I don't want to go to Burton, I'll just wait for my bargain bundle

Well it's ALWAYS a portable trebuchet.

Or better to say a trebuchet is a semi-portable large scale staff sling.

Length.
Well I'd say that's mainly limited by two things.

1) ease of use. IE reloading and throwing

2) ease of transport.

Like with long slings there has to come a point where it's just too unwieldy and you get more distance with shorter easier to use staffs.

I reckon you could probably go to 8 feet fairly easily.
And obviously the size of the slinger will come into it.

I'd love to get Hathor bjornsson into slinging

Six foot 9, 400lbs of just pure ultra fit muscle.
And he's fast as well.
That bloke could probably break all existing sling records and create a whole new bunch as well.

Unfortunately we don't have any currently active Icelandic slingers. We used to have one, but he's not been around for ten years or so.
So little chance of getting someone to 'ambush' thor with a sling demo.

This is the longest staff sling I have seen used, he lays the pouch and cords along the ground like a trebuchet. It looks like he is getting plenty of power into the throw. https://www.youtube.com/watch?v=_ajTNkvAqt4&ab_channel=FingerAngle
