Also available for purchase at http://etsy.me/1bi4jyG I found a portal turret model on Google sketchup warehouse: http://sketchup.google.com/3dwarehouse/details?mid=79e8c33cb58058acd01371e29b8b3832&prevstart=12 There is no way for me to contact the original author about authorization.. and the terms are seemingly ambiguous for Google Warehouse, so I'm not sure if I got the license right. Also check us out on Facebook! https://www.facebook.com/carry.the.what.replicationsPrint each piece separately. Print the main body upside down, so the peg holes are un-hindered. Print the legs on their side. Then slide each leg into it's corresponding slot! Snug fit on my Up! printer, let me know if it works on others!
