50mm Paint Corners

[dwardio]

This morning I realized that I needed some paint corners, Not wanting to wait a couple of hours for 3D printed stands, I used my glowforge and some scrap 3mm (1/8") plywood. Entire project from need to design (5 min in AI) to a dozen stands took less than 30 minutes.

Remember – 3 points are inherently stable, 4 are almost guaranteed to wobble.

Here’s the file in case anyone else might find it useful.

Press fit a short piece into a tall one on a flat surface until the bottoms are even
(the slots are sized to leave a gap for tolerances/fit).

Edited: Slots are 3.0 mm, scale up or down to fit your material.

Thank you for this practical file.

These will be handy! Thank you!

Very practical…

… but I have no idea what it’s practical for. Googling “paint corners” only leads to millions of “how to paint corners” results.

You lay a painted/finished item on top of them. That way the points of contact are really small.

Perfect timing, I was just thinking last night I needed to get some made. Thank for the share and time saved.

Probably dozens of regional names, but they hold painted / stained parts off of surfaces…

I’m making a quilt stand for my wife. All the non-dowel pieces were cut from 3/4” Baltic birch using my Shaper Origin.

Great practical cut. I need some of these as well! Thanks for the share!

Thank you! This will come in handy.

I made little tetrahedrons a while back:

How to remove masking from 423 parts at once

I made it ridiculously large because I definitely don’t want to misplace it. It’s bascially a very simple 2 piece tetrahedron. [image] These would make a good pin bed setup for finishing. 4 of these make nice little pointed risers so you can let your finished woods dry in peace. You’ll probably want to scale it down to be a reasonable size, but definitely paint them a bright color so you don’t step on them. Eesh. simpletetra.zip (1.7 KB)

Would be pretty easy to scale these down, but the design in this thread is nice and simple and will support more weight than the caltrops can.

I needed some paint corners

Always found the square head roofing nails prop things nicely.

However, good use for a lot of the scrap laying around and less of a concern about keeping track of how many loose square head roofing nails are in the room.
They would make a good ninja like escape plan. Toss a dozen or so behind you and a lot of them will be pointing up when done bouncing.

Practical and will work better than the ones off Amazon for sure! Thanks for the share

I just bought some a few weeks ago. It didn’t occur to me to make some on the Glowforge, but this is a great design, and next time I’m likely to use this rather than go buy more plastic pyramid ones.

[ellencadwell]

Nice, thank you!

[sdmeier]

Brilliant! I love functional stuff like this. Thanks for sharing!

[ptodd]

These might come in handy very soon! Thank you!

[usnerdoc]

Thank you for sharing! This is a very practical file / project that I can put to use in my shop.
