Hi there.
This is a work in progress of an idea that born in my mind during a car commuting.
The basic idea is simple, i want to try to build various kind of activable trap door for dungeon tiles.
the first result is this one, the shield could rotate and activate a lock on the door, the door and the basament have both place for magnets (i use the 1mmx5mm) and placing on opposite side force the door will open as soon as the pinion move thanks to the gear activated by the shield.
So, you can glue it on a 4x1 openlock base and add to your dungeon!

As i said at the start, this is a big wip, i mean, the pieces are all printable (i printed them making some versions) BUT there are work to be done at the moment:

• the pivoting pole of the trap door appear weak and need to be strenghted,

• to let the pieces connect, some sanding is required

• the trap door itself, need to be sanded on the pivoting side, i will (probably next week) redesign it with reduced attrition zone on the pivoting side.

the others trap doors will come as soon as possible, i'm planning (designed already) a magnetic floor plaque activating trap door, and a simple lever activating door.

Now some words (probably is a rants) on you:

• i have fun making printable items but,i'd used many hours of my personal time on those pieces and sometime it is hard to share them on internet, in fact i reduce my uploading because i see many ppl just downloading it without even leaving a thanks or a like.
  Is really wierd to my eyes and maybe, this could bring to some change on future, to be honest a like don't cost nothing and for a noob designer/makers is a very good vibes.

so if you like it or print it, please let me know or pay me a beer ! any kind of feedback is welcome yes also the angry ones!

happy printing, and happy summer
