Looks like the world has changed since I used Rhino. Grasshopper used to be a cost-add plug-in which gave it parametric capabilities. Rhino by itself was not parametric. But looks like ~v6 it was incorporated into the base Rhino package. Some things I miss about Rhino, others not so much...

I happened to be in Industrial Plastics & Paint Calgary store & noticed they carry Weld-On #16 an acrylic cement. People claim is quite good bonding PLA & other filaments. Not cheap ~25$ for the larger 5-oz tube. I tried some samples & it does appear to bond quite well. I'm going to guess it...

Looks like discontinuing so maybe reason for sale? https://www.kbctools.ca/itemdetail/1-808-154902 https://www.itm.com/product/mitutoyo-154-901-small-hole-gauge-set?srsltid=AfmBOoq_mSy6MVMbeYLkPJ1fKvjY8hp3y5Cjae4pahpuXkPfKCgrZu3Q

I take the time to clean metal swarf out of the tray beforehand as a precaution. Plastic swarf wrapping up on itself is bad enough, but if it picks up swarf from the tray it makes for unwanted excitement. Unfortunately the best tools to cut it (sharp cutters like for aluminum) don't really do...

I linked an interesting post where he harvested digital level / angle finder for use on RT. Maybe not adaptable to a compound because he is utilizing the rotating bit with a bit of adapter machining. Anyway, maybe it will trigger some ideas. Lots of DRO-like encoders that read of thin 'tape' &...

That's wild stuff. I had an opportunity to lurk in on some comps & workshops through my buddy who was one of the mentor team for his high school daughter. Some real world life skills, career compassing & I suspect lots of good memories will result from that experience. Good on you for...

Thanks @architect after some more reading I came to similar 'potentially complicated & all depends' conclusion. So I just kind of given up for now. I have a feeling it must have something to do with motherboard because the various BT earbuds & headsets work on other devices. Odd because my PC...

That's a good point. Sometimes the filler material and/or the resin can be very hard on cutting tools. I use G10 type board for certain components (glass & epoxy) & I can go through HSS blades & cutters at a rapid pace compared to cutting wood. Carbide lasts longer if available but depending on...

Looks good. You have enough of a pin roller outline you could even augment with Sharpie marker. I forgot there might be possibility of the protection layer plastic, so I guess it all depends on what kind bending & cutting operations is going to occur. Back in the days of laser printers (well...

I've had to do equivalent things to that with composite material layups into molds. Various materials needed to be orientated or laminated in a certain way & many had had perimeter offsets or allowance notches. Its kind of like a sewing pattern. In the end I had dedicated patterns. Some had...

I'll take a look again & maybe varies by manufacturer. Seems to me they have kind of a skin layer & a core, so might be limited what you can skim off. Mine looked flat with embossed grain, presumably through the rollers, so I don't think would be a problem from that standpoint. Actually what I...

You just reminded me @Tom O I have a few chunks I grabbed as samples from some lumber/flooring place. I wondered out loud if swelling might be minimized or mitigated because its obviously weatherproof. This particular sample has kind of embossed fake wood grain, but its still reasonably flat...

Same for me, use it quite often as a flat-ish backing board material like drilling through or machining edges where the EM extends through a bit. I even made a mockup fixture plate from MDF but it was for a small part & low quantity. But you need to use metal blind nuts or threaded inserts, the...

Less than just the points, go figure.

Mitutoyo actually sells center points for calipers. Don't look at the price or it may blind you. I have seen aftermarket points too. But they just use a pair of set screws that tighten on the jaws, no modification to jaws is required. Not sure if their image is intending to demonstrate they can...
