Anyone used online 3D printing services

Hand fettled some cranked, 1mm copper sheet for the battery connectors. Tight fit so tapped them in with a soft punch. Vice marks...should have used soft jaws I know!

 

 

They need to be drilled to accept the wires:

 

 

Unfortunately the tight fit/my hammering caused the print to start to split and delaminate. The slots were only 1mm wide as is the copper.

 

 

Now then, anyone care to spot the deliberate mistake?

 

 

Not insurmountable, I could just split the tool to get the adapter in. I have to any way to solder the wires on.

 

Looks like a redesign is on the cards!

Slightly off topic but fair play to this lad. Only 28 and suffering colon cancer. He's 3D printed his tumour!

 

 

I must dig out my spinal MRI files and print the damaged disc section! ?

There are numerous ways for a 3D printer to go wrong and produce poor quality prints. This one was new to me...

 

Can skip to the cause at 7:32...

A couple of incarnations of a Makita 18V battery to Einhell/Ozito adapter. Ripped off Thingiverse. Been using a previously printed pair in the Einhell chainsaw and they've worked perfectly. I took them out to play with a "sold as seen/spares or repair", Einhell brush cutter and have misplaced them ?)

I used RS Pro, black PLA last time. This time, clay red PLA from 3DFILAPRINT and grey PETG from 3DJAKE.

The Makita side:

 

 

Any pointers as to reducing the hairiness of the PETG?

The Einhell, Ozito side. In both cases the battery release lever snaps off as soon as look at it. Tbh this is the weak point of the design. A bodge to stick it back, that works, is a slug of CT1 and let it set. It acts as a spring!

 

 

Anyone on here able to offer laser cutting in 1mm copper for the tabs? If not it's another hand fettle job.

[Temp]

I also get more stringing with PETG.

 

You can try..

Lowering nozzle temperatures 

Increasing retraction distance

Increasing retraction speed (or reducing it if too fast)

Increasing travel speed (eg less time to ooze between printing)

Enable wiping (not all slicers?)

Enable combing if not already on.

 

 

 

 

 

[dpmiller]

pass a heat gun or blowtorch over it?

Just been using the 36V Einhell chainsaw with the 3D printed adaptors and Makita batteries. Didn't skip a beat.

 

For a little diversion:

 

A brake servo bodywork grommet for a Ford Capri in 95A Shore TPU.

Test run at 20% infill. 

 

 

 

Aim is to try and recreate the lettering!

Just seen that Anycubic have the i3 Mega S on a back to school sale. @PeterW put me onto Anycubic when I wanted a printer for my lad's 21st. To say he's had fun with it and learnt, whilst at the same time producing practical prints is an understatement.

 

With hindsight I might have gone for an Ender but at this price you can't go wrong.

Don't drink and 3D print kiddies. Can you guess what it is?

What looks like filter material is actually removable support structure that gets binned, so no!

Something for Tracy Emin, now she has lost all her female bits.

She is one of your local girls.
