Fun CAD update

Beautiful, thank you. Aliexpress to the rescue once again.

Ok yeah I like that idea a lot too. The one thing that’s crossing my mind now is that the heat from drilling might cause a 3D printed jig to melt or deform. Might not be enough heat to cause issues, but only one way to find out.

I wouldn’t think that there would be. Most of the things like the Kreg pocket hole jigs have those bushings pressed into plastic housings and I’ve never seen anyone melt one. I always use a bit of PTFE spray-lube on the bushings with the couple of jigs that I have, anyway. That and some WD40 or cutting oil on the aluminium and it shouldn’t get appreciably warm.

Shoooooot, I swear I read that twice. I thought you said 3D Printer. I only have a Thermal label printer at the shop. 2D printers don’t get used enough and die / clog on me.

Hahhahh that would be ridiculous. I couldn’t live without my 3D printer at this point. It’s just another appendage at this point

I bought a cheap thermal printer for the 4x6 shipping labels during black Friday. That makes things a TON easier! But I do still have a 2d printer, 2 actually but one is loaded with sublimation ink.

@CarmenJ keeps our ink flowing with her “daily list” :rofl:

That’s definitely the way to go. For me it’s usually a box of several hundred units once every couple of months so the laser printer + tape gun + cursing usually gets it done. I would like to get a better PC connectable label maker, which leads me to looking longingly at the heat-shrink cartridges for them, then checking prices, then realizing that a black marker and white heat-shrink is more my speed :expressionless:

I have a label maker that can print on heat shrink, but its not PC connected. I can only imagine that raises the cost a considerable amount, but probably makes it a lot easier to use as well.

It’s the heat shrink cartridges that are eye watering here. I think the Brother ones I was looking at were $50-80 each and that’s only something like 1.5m of heat shrink. I don’t mind spending $500 on a label maker but really don’t want to get saddled with then needing to buy $400 of consumables :expressionless:

Yeah that’s nuts. I found some off brand ones that work in my Rhino 4200 that aren’t too bad. And I don’t go through enough of it to make me remember either. Its one of those things that just real nice to have and I caught it on sale lol

CartridgeKing Store On aliexpress - I got Brother compatible heatshrink cartridges for a very reasonable price.

Also got nice gold on red ribbons for Christmas present wrapping and iron on garment labels from the same store.

OH MY WORD, WHAT if you were to make this into a 3d printer as well! replace the router with a printhead :slight_smile:

I better say, obviously i KNOW it cannot be done, I said this in jest!

That’d be a pretty funny idea. Basically one of those free-form 3D printing pens, but with more automation.

I wouldn’t say cannot be done… Hell of a lot trickier, for sure.

Hahahah it’s crossed my mind. I wouldn’t write it completely off, but also not sure if I’d want to be the one to try and tackle that :laughing:

Our 2D laser black and white printer is over 10 years old and I think we are on the third toner cartridge. When we need color, we print at kinkos or order prints online.

Beta unit looking and feeling a lot better. Countersinks, flat head screws, new PCBs, and a few new printed parts.

This comment motivated me to get on with an idea I’d wanted to play with of making a pizza ‘stone’ from some spare 6mm aluminium we have around at work.


That’s the result using a 1/2" pattern bushing and a 1/4" carbide spiral bit to routed around the outside of a laser cut pattern. That’s showing the lead in and how clean the result is. I was doing the cut in a single pass, so 6mm DOC, ~5mm trim at maybe 5-10mm/s with what felt like probably ~5kg of lateral force. With the router in the lowest speed setting you can definitely hear it loading up but it doesn’t bog, didn’t get more than slightly warm and was throwing beautiful sliver chips the entire way.

Gorgeous stuff. I wanna see pizza pics. Seems like there’s a huge rabbit hole to go into with this pizza stone stuff

There really is. There’s also some uniquely frustrating arguments to see about it.

If it turns out amazing then there’s a local metal supplier with a 10mm thick 316 stainless steel plate offcut for $100 that would be a hilarious option.
