Had a great session last night teaching #rocket design to 11 interested people of all ages! Showing off #opensource tools #Openrocket and the fabulous @FreeCAD rocket workbench. #FreeCAD

Realised I'd neglected to post about my @FreeCAD book on here. "FreeCAD for Makers" is out and available for free download now via Raspberry Pi Press. Huge thanks to the Hackspace magazine crew for getting it together and the mighty @yorik for the foreword! #opensource #CAD #CAM #FEM #Makers DL here https://t.co/e0Sk0I49Td

Tonights #sewing adventure. These bags sometimes get called "stash and go" bags, made from 2 circles and some binding. It's less good than the pictures look but a good exploratory first go! #making

Got access to a #lasercutter? Did this today, grab an accurate measure and work out the height of marks needed to turn a discarded jar into a measuring device! A quick @inkscape of the measurements and then to the #lasercutter! #reuse
