Just a simple knob to replace a number of selector knobs that broke over the last 20 years on my Kenmore washer and dryer.

Print and remove the exterior perimeter wall, as it is just support for the knob top.

This "thing" is a stub for the laser cut files for the Prusa i3 printer frame for use with wood, acrylic, and other thin material. Published under GPL v3, same as the Prusa i3.

Grab the files from my Github repository: github.com/sgraber/Prusa3_LC

I have provided three file types: dxf, eps, and pdf.

In case you have RAMPS mounting holes on a frame but want to mount an Azteeg X3 board in its place instead. Use this and you're set.

This game harkens back to the 1965 Barrel of Monkeys game originally made by Lakeside Toys (now made by Milton Bradley). Each game came with a colored barrel and twelve monkeys the same color as the barrel. The instructions of the game stated: "Dump monkeys onto table. Pick up one monkey by an arm. Hook other arm through a second monkey's arm. Continue making a chain. Your turn is over when a monkey is dropped."

My version uses twelve octopuses instead of monkeys and features a custom octopus graphic on both the top and bottom of the barrel. How many can you pick up?

This is a simple mold to allow people to make their own sidewalk chalk crayons. It is inspired by the Bloxen, Sidewalk Chalk Mold 'thing'.

My boys used to use this stuff on our driveway all the time and they loved it!

Used for hanging piping from rafters, joists, walls, etc.

I needed this for hanging a section of PVC pipe from a ceiling joist to hang my filament spools. Worked like a charm.

This is a simple venturi injector for injecting air into a fluid stream.

This is one of the models from NASA's 3D Resources located at nasa.gov/multimedia/3d_resources/models.html

This particular model is found at nasa.gov/multimedia/3d_resources/assets/friendship_c2.html

This is a simple clip for holding nori seaweed or other vegetable matter for herbivorous fish to feed on in an aquarum.

This is a simple mixing eductor that one can use for in-tank mixing applications. The spars are a bit weak due to the thin walls but it's functional.

This is a simple seahorse hitching post feeder for feeding frozen food to your seahorses.

This is a simple connector to join two 2-liter bottles together to make a Tornado Tube experiment for your kids.

Fill one of the 2-liter bottles with water, connect, swirl, watch the tornado!

This thing is a bracket that holds up a piece of 14 mm eggcrate using suction cups from a spare MaxiJet powerhead. The eggcrate platform can then be used to hold coral frags inside an aquarium until they have grown out or until you are ready to sell them at a local frag swap.

This is a simple sponge filter for breeding and larval tanks.

It requires two zip ties, a porous filtration sponge from your local fish store, some airline, and an air pump.

Assembly is pretty simple. Print this out, attach an airline, wrap the standpipe with the porous sponge and zip ties, and attach the air pump. Done.

This is a simple brine shrimp hatchery base for culturing brine shrimp for fish breeders.

Print it out and screw on a plastic 2 liter bottle with it's base cut off (see photo at left).

Once printed, I suggest brushing the inside with acetone to make it water tight. Optionally, add a rubber o-ring at the bottom of the threads to help seal it even more. Attach the airline from your air pump to the nipple protruding vertically from the hatchery base.

Make sure to use an airline check valve in case of a power outage as one does not want the water in this hatchery to back flow into the air pump.

This is my 3D printable version of the Wobble Chess set:

uncommongoods.com/product/wobble-chess-set

Print and fill the hollow bottom with sand, mortar, or anything very dense. Glue the top on the bottom once dry.

The heavy bottom will keep the chess piece upright.

Just a simple set of crayons shaped like chess pieces.

How many of you remember playing with wooden Fisher Price "Little People" when you were kids? I know I do. Now you can print a set and play chess with them. :)

This Thing is a coral frag plug that is used when propagating coral (i.e. "fragging") in the saltwater aquarium hobby.

The post for this frag plug has been made removable making it much easier to glue a mounted frag into place in your aquarium as you now don't have to deal with the post being in the way. Rejoice!

Coral fragments are either cut or broken off of the mother colony and then glued to this frag plug using cyanoacrylate gel (superglue). The resulting fragged coral plug is mounted into 14mm eggcrate that is submerged in the saltwater aquarium where it is left until it is either traded with another hobbyist or sold at a frag swap.

I have uploaded four variations on a concept that I have been toying with for what might be useful to a coral farmer. I am keenly interested in optimizing this concept so that it Works for those needing a good, quality, multi-purpose coral frag plug so please leave comments on how I might improve this Thing.

These are simple connectors for building your own Korean fighting kite.

My son needed to build one for his project on Asia so I designed and printed out corner connectors, t-connectors, and a central connector with my Cupcake.

I went with this design for our kite:

kiteplans.org/planos/coreen/coreen.html

You will need to use Google Translate to translate the page from French to English. One thing that I did was up-scale the dimensions of the kit a bit so that they're slightly larger than the metric-to-english conversion on the above design.

There are similar designs on kiteplans.org/pln_1564/ as well.
