Random 3D printing chatter

Anyone used the colour 'card' things you can print, with filament names/details/specs on?
I saw someone post about them somewhere and didnt flipping bookmark it..
 
Did some threaded inserts today! Was intending to use machine screws in printed holes but the sizing wasnt quite right. Will definitely consider more designs using them in future, very neat and effective.
Are they the ones that you heat into the printed piece? Which ones did you use?

Like the swatch holder for the cards that come with a Bambu printer? I printed one and used a printable 608z bearing for it :


 
Nah, the thing I Was thinking of was smaller than a credit card but allowed you to put the details for that particular filament on it, nozzle, flow rate etc..

Not discouraging the use of inserts but if the size is wrong, provided it's too small, you know you can run a tap down the hole to get the threads the right size? Not much help if it's too big... although a roll tap (aka form tap) might do it if it's just a little oversize.
Similarly a reamer (preferably sharp rather than the blunt kind that imports tend to be) will bring a hole up to size and make it round. Often a good way of cheating if you need the hole exactly on size but don't want to play about tweaking the size until it happens to print just right.
 
Something like this is what I Was thinking about, but the one I saw had details for the filament on there..

There's a parametric one here to generate your own :

They are, using a soldering iron with a setting kit on it. Just got an assorted set of brass inserts from Amazon for like a fiver.

The holes were oversized, which was surprising given that I expected the ABS to shrink if anything.

I've since run off a calibration print and configured some X-Y offsets and got to around +/- 0.5mm but not yet tested some new prints.

Thats the badger..

Aim for too small and as long as you've got a few walls round the hole, bring it up to size (or tap it) once everything has finished shrinking.
Also, mind the fumes off ABS if you're heat setting inserts in it.
If it must be ABS (and I've yet to find a good enough reason to fight the stuff) there's an ABS-GF that's supposed to warp a lot less. Bambu do some. Clough42 used some to print a control panel for a CNC grinder and it stayed flat enough to put together where straight ABS warped too much.
