A Tub Drain Stopper is my most practical model/print yet. Simple, but useful. Worked to 97% effectiveness over 3 day test.
Keeping my journal of 3DPrinting projects at http://www.MkrClub.com
Modeled with 123D Design?
yes. really simple there.
I’m going to start posting 3D Modeling videos soon for ppl new to this part (kids in particular)
@Jonathan_Rochelle Good to hear that. 
I’m going to start a modeling and 3d printing course in August (6th to 9th graders).
@enhydra that sounds awesome - do you have a curriculum outline you are willing to share? Any details on the setup of the “shop/lab”? So many people ask me about that - i would love to share practitioner examples.
Want to do a guest post on http://www.MkrClub.com ?
@Jonathan_Rochelle I would love to do that.
In the next weeks I’m going to summ up a scenario from my last course on http://3dgeometrie.com (German). I’ll get in touch with you when I’m done.
