Hi

Since my last post I have worked out a new way to make a "house" model as shown in my last design post. This is a vast simplification of my previous effort - instead of custom made 3d printed joiner parts - with a different part type for each of the 60, 90 and 150 degree angles - I've just used clear tubing with a different length for the different angles.  The tubes get cut different lengths for the different angles though.

So the bits of balsa are 8mm thick and the tube goes right through 2 of them. Then you have to work out the length of  tube that goes in the middle. If the diameter of the tube circle is D, this length is the circle circumference multiplied by the circle fraction. So for 90 degrees we get the length

(90/360) * D * PI + (2 * 8) etcetera for the other angles.

Anyway, its fun but a bit mathsy.

Best wishes

Steve Nurse
