Howdy at ya -
I have been seeing these at Amazon and Home Depot, and decided to make my own. Those folks want around $5 (plus tax and driving and ...) for 10 of them.
I figure mine are around 25 cents (USD) for about 20 of them... Probably less... Granted - they claim their points will hold 200 pounds. I make no such claim. I will guarantee they will hold a 1-pound box - which is about what I wanted to paint...
I saw the ones presented by Obediah, and those are Way Dang Cool also!
OF COURSE, I made these at TechShop on the laser engraver...
Step 1: Check Out the File
To make this one go fast, I integrated 4 of the pyramids into a single vector file. This is what it looks like...
Step 2: Hey! Cut It Out!
Here's an eps file which can be imported into Adobe Illustrator, CorelDraw, or another of your favorite programs for cutting on the laser...
I use CorelDraw, just because I'm used to it.
I used 1/8" MDF for these because it is WAY CHEAP!
Step 3: And the Result Is...
... a bunch of triangular pieces. Three pieces per point/pyramid.
Step 4: And Assemble 'em...
I like to use White Glue for anything I cut in MDF. Mainly because the stuff is usually headed into children's hands, and I want to make sure I remain PC (parentally-correct...).
I used a bit of tape to hold 'em until they dried.
Step 5: And There Ya Go!
Let the glue dry and set.
And now you can use them to hold up your piece while painting it!
