Update: After Shapeways tweaked their pricing. I’ve moved over to selling them online at https://badgly.com/. I’m keeping them on Shapeways, but I have a lot more control on Badgly. Have a look there and feel free to use the 5OFF coupon code for 5% off.
When buying a house, you always find that there are some parts of the house that the previous owner had something installed, and the bag of spare parts and the supplier they used are lost to antiquity. This some times only gives you the option of replace, hack, or just live with it. This happened in the house we bought last year.
The shelves in the kitchen don’t have your standard Ikea style shelf pegs that hold the shelves up. Neither do they have the standard shelf pegs you can buy at home depot. These are custom jobs created by some unknown manufacturer. Not only are they non-standard pegs, but the holes they fit into are not only custom, they are a funky insert, twist and lock style.
After a discussion with a colleague at work I thought I’d 3D printing. After going through a bit of a process, I ended up ordering a set from shapeways.com. Here is the comparison of the original with the new.
Ultimately, I ended up with this shapeways part. I’ve included a rendering below.
The pricing model that Shapeways uses includes a per-piece handling charge. Individual items of this size are not economical when comparing to a Home Depot single-part-but-unusual shelf peg for $2.20, this opened my eyes are fair bit.
Taking a leaf out of the plastic model aircraft, I connected them together with 1 mm sprue as shown below. Four connected this way came out to to be within striking distance of small over-priced anything made of plastic that you get at the store. I’ve tested the fit, and they seem to work well. The strength passed my “I’ll try to break it with my hands” test, so it will probably hold the shelf up really well. After discussions in the comments below, I have now made sure that publicly the 4-way model is purchasable on Shapeways. (Note that I now have them listed on https://badgly.com/.)
What would Magyver think of this?
