My 9-year-old daughter is wanting to help support Ukraine, and decided to make cookies to sell, donating the proceeds to the relief effort in Ukraine. I designed this cookie cutter for her cookies - she plans to make simple sugar cookies, which are reasonably dimensionally stable through baking, and she will ice with yellow and blue buttercream. You can see a test run made with a slice of bread.

The cookie cutter is horizontally 'flipped' so that the cookies come out in the right orienation.

There are two versions of the cutter:
* ukraine.stl - printed 'as is', this should produce a cookie 80mm wide and 56mm tall
* ukraine_large.stl - printed as is, this should produce a cookie 160mm wide and 112mm tall. The blade is the same thickness, but the base is beefed up a bit for strength.

**Recipe**
This basic sugar cookie recipe works well:

* 4 cups flour (might need to add a little extra if dough is too wet)
* 1.5 cups sugar
* 1 cup of softened butter (~225g)
* 3 eggs
* 0.5 teaspoon salt
* 1 teaspoon vanilla
* 4 teaspoons baking powder

Cream sugar and butter together, just until mixture is fluffly and light. Add the eggs one at a time, and beat the mixture again after adding each egg. Add the vanilla and mix well. Mix the flour, salt and baking powder in another bowl, and then gradually add to the dough mixture. Mix well.

Knead the dough into smooth balls, and roll out on a floured counter or board. Flour cookie-cutter blade and cut out cookies. Bake at 180°C (350°F) for about 10 minutes.
This made 15 of the large-size cookies and 34 of the small ones. The dad... may have misappropriated a small amount of the dough along the way.

**Baking Notes**
We rolled our dough out to about 6mm (~1/4 inch). The large cookie cutter worked effortlessly. The small cookie cutter also worked well, but Crimea sometimes got stuck and had to be carefully winkled out of the cutter. Both large and small cookies look pretty good after baking.

**Donate**
Please feel free to use this design to raise funds for relief efforts in Ukraine. The cutter is quick and cheap to print, so maybe print copies for like-minded friends! If you are not sure of where to donate, the work being co-ordinated by the European Baptist Federation is amazing, and there is a desperate need for funding:

Volleyball Four-Square, AKA "four square in the air", is an exciting combination of four-square and volleyball. It requires the creation of four three-dimensional 'cells', open at the tops but clearly delineated. This Thing assumes you will build the frame from 40mm plastic drainpipe, and provides friction-fit fixings to assemble them into the three-dimensional structure. The friction fit makes it quick and easy to assemble and pack away.

#How To Play#
These are our 'house rules', you may wish to fine-tune for your setting. Consider this 'top down' diagram:
![Volleyball Four-Square Rules](https://cdn.thingiverse.com/assets/87/5e/63/b0/c1/Diagram.png)
Each 'square' is numbered 1-4. One player stands in each square, the player in Square 1 is the king/queen. If you have more than four players, we set out a chair for each extra - numbered 4, 5, 6 etc.

The 'king' serves the ball up through the top of their square, and it must come down through any other player's square. That player must then return the ball, up through the top of their own square and down through any other player's square. Each player is only allowed one touch, although we often add a rule permitting a second touch if the ball bounces off the frame.

A player loses if the ball comes down through their square but they fail to return it. That player goes to the end of the line (ie the last seat in the queue), while everyone 'behind' them moves up. For example, if the king loses, they go to the end of the line and everyone else moves up one. However, if the player in square 3 loses, they go to end of the line, while the player in square 4 moves up to 3, the player on seat 5 moves up to square 4, and everyone else in the line of seats moves up.

A valid serve goes up through the king's square, and down into another player's square, without touching the frame. We allow the king a second serve if the first serve is bad for any reason - if the second serve fails, the king loses. Generally speaking, play moves so quickly that even if a player is last in line, they will be back in the game in just a minute or two.

#What To Print#
For four-square, you will need to print:
* 1x centrepiece
* 4x edge
* 4x corner

#Plastic Pipe#
You will also need 40mm plastic waste pipe for the frame - I used FloPlas WPO2 40mm White Polypropylene Waste Pipe. '40mm' pipes are available in different materials and have slightly different diameters - adjust the parameters in the OpenSCAD file if your measurements are different - a good, tight fit is necessary. For four-square you will need to cut:

* 12 horizontals - I cut mine to 1.5 metre lengths, which works well for the game and means I can get two out of each standard 3-metre length of pipe
* 9 verticals - I cut these to 2 metre lengths - high enough that they're 'overhead' for everyone, but not beyond the abilities of primary-school children

#Assembling the Frame#
If you have many helpers, assemble the frame top on the ground, then lift the assembled top frame onto the uprights. This is quick and easy. However, it is also possible for one person to assemble the frame on their own. To do this, start with the centre connector and an edge connector. Assemble these into a n-shape with two uprights and a crosspiece. Now attach a corner connector to a cross piece and an upright. Get the n-shape standing upright and attach the cross piece with the corner - now you have half a 'square', free standing. It should be easy to complete this square, and then build out the rest of the frame from there.

Because the pipes are not very rigid, you may find the frame a little flexible/wobbly. This doesn't seem to interfere with play, and the connector parts are strong enough to handle the stresses. The friction fit joints seem to hold reliably, but after a hard spike or epic collision they may need a quick tightening-up.

A simple tripod mount for the Logitech C270 webcam. With so many churches needing to stream services because of the COVID-19 lockdowns, and a shortage of webcams, I hope this will help someone deploy their old C270 - a decent camera, inexpensive and still relatively easy to get hold of.

The original (and rather silly) mount needs to be removed from your C270. There is a  pin running through the hinge at the back, covered at both ends by a tiny rubber pad. Remove the rubber pads with a pin or small knife, unscrew the locking screw at one end and then push the pin out. You may be able to reuse the pin to attach the camera to this mount - I just used an M3x30 screw I had to hand, which worked very well.

The hole in the base should be just right for the 1/4" thread of the tripod to "bite" into - no nut should be needed. 

Hopefully you can just use the STL, but the OpenSCAD source is provided just in case.
