This is a 3dPrinted Standard Portcullis Assembly, which includes a standard door frame and single Portcullis. These are printed in PLA.
Note that there are multiple Door frame options available.
Here are the advantages and disadvantages of the Standard Doorframe , compared to the others:
Advantage – Works exactly as intended with Gridscape terrain. Fits perfectly inside a 1”x2” space, only using the exact amount of space necessary to work with other terrain pieces.
Disadvantage – When 3d Printed, this version has corner pegs that are 1/4 semicircles, which are prone to breaking (especially when dropped). These are printed at a 45° angle to lower the odds of this happening, but this is the main disadvantage of this door frame.
