Snap On Portal BooksStand
by humberto, published
Adapted from the Portal bookstand (by konrad44, http://www.thingiverse.com/thing:25396) now a snap on kit, with separate pieces so you can mix and match you favorite colors.
Update: Now with scale-corrected STLs and SKP files.
Print two stands, each person side and two portal ends (one in each color if you like. Snap and use :-)
PS: you may use the slot and snap form to devise other snap on bookend decorations.
