Lye and PLA

I was reading some old nophead blog posts and I found a small part on how pla dissolves in lye. Which is interesting because it would be nice if there was an equivalent to acetone smoothing for pla.

I’ll have to do some tests later.

Kratky Hydroponic method in Mason Jars

I’ve wanted to try out some different hydroponic methods. One of them was the Kratky method. No pumps nor recirculation at all. Basically just some contained water and light. Awesome! Sounds simple.

So, to simplify things, I’ve went and painted some mason jars black, and printed out some net pots to hold some catnip plants. I’ve started some catnip in my planters outside, and I’m hoping to get some growing inside as well. I’d love to put my own catnip inside of the pillows I sell.

The net pots I got from thingiverse and for the parameters I came up with the following STL: Mason Jar Netpot

1/4″ HR Valve Adapter

So, I have a friend who needed an HR Valve that was useful…if you search online for HR Valve adapters, all you find are ones with a 3/4″ish barb on it. Which, if you are wanting to use an air compressor, you have to have quite a collection of different fittings and adapters to connect.

Well, we found one on thingiverse and it worked mostly well. But at 99% scale, it fits perfectly!

I’m also going to sell printed ones here, and on Etsy, Amazon and eBay. Because why not? It was printed at:

  • 0.99 scale.
  • 20% infil
  • 0.2mm layer height
  • using PLA plastic

So if you have a printer of your own, print it instead of buying! Otherwise I’m selling them at $10. Mine include pretty packaging though, so if you’d like that, please buy!

Spoonflower Gimp and Inkscape Palette

I’ve been playing around with some of Spoonflower fabrics. One of the small challenges that I’ve had is matching the colors they’ve picked as their fabric palette. They have a palette file (a .ase, used for Adobe products), but since I try my best to use FOSS, I can’t directly use those. I tend to use either GIMP or Inkscape for all my graphical work. Most of the convertors I’ve found are old and unmaintained, so they didn’t work well. Then I found gpick, which worked wonderfully! Certainly saved me the trouble of having to write something that converted from ase to gpl.

But, if you don’t feel like downloading it, I’ve also attached the converted Spoonflower palette!

Cat pillows and bells.

New option!

Some ideas are obvious after they’ve been thought, including the fact that cats love jingly things!

But their owners don’t always, and that’s why it’s an optional add on to all cat pillows! If you’re cat loves bells, but you don’t, you don’t have to order them with it. We’ll keep it between us.

Catnip is the most familier plant used for cat enjoyment. Also called catmint, about 70% of cats enjoy it.

Can be dried and saved for later, as well as buds saved for maximum cat enjoyment.


Catnip enjoys well draining soil, and moderate sunlight. Does extremely well being grown via hydroponics. Enjoys a wide range of ph from 6.5 to 7.8. In soil the cat likes approximately 25×25 cm of space per plant.

Very flexible, and very hardy.


Catnip blooms from July through October. After the flowers mature, seeds form. I am not entirely sure if the blooming and seeding process is time or temperature dependant. Most likely both.

Seeds take 7-10 days to germinate. It can be easily started indoors due to the plants flexibility.


Catnip is essentially a weed. It will grow in most conditions, and loves to spread. Easy to grow, dry and prepare for all cats. Uses a similar nutrient blend as any lettuce, so any hydroponic project will be successful as well.
