This is the design for a play tower in Bangkirai wood that I had actually wanted to put up in our garden. Sadly our building authority thwarted the plan with conditions such as registering a land charge with the neighbour and commissioning surveyors — but perhaps someone has more space on their plot and doesn't have to build close to the boundary. (And yes, my granddaughter got a nice "structure" as a replacement, too ;) )
From an OpenSCAD point of view, the for loops are especially interesting:
// planks towards the wall
for (a =[0:13]) {
translate([1360+45+20+a*(145+10),45,1500+90])
dieleY(816);
}
a takes on the values 0, 1 up to 13 in turn. Accordingly, the 81.6 cm long planks are shifted in the x direction.
