Thank you very much.

I used brackets from same supplier as the extrusion. All 90 deg external and some internal L shaped. They're not automatic but are easy to use.

Can't you just screen shot it, then print?

No, but this one is!https://www.instructables.com/id/E-Trike-Activity/

Check out my Trike, perfect for the older racer.https://www.instructables.com/id/E-Trike-Activity/

The laser was actually pointless, you'd be better off drawing the schematic in black pen and self tapping the larger components directly into the play.. You would need a 3d printer though, or be very accurate with a handful of polymorph (low temp plastic)

yep, i'll try and share a less bone bucking design later this week. a trike.
