Flat version of AMS riser. Glass holder STEP file is included. Print from PLA, but if you mostly print high temperature materials i recommend printing from ABS. I connected the parts using steel pins (6x30), but I included pins for print.

If you want or need, you can print a reinforcement between both sides. I use one reinforcement in place of the seam, but it isn´t necessary.

V2 - ABS:

Added radius on hexagon holes for improved stability during printing overhangs.

Added connenting cross for connecting parts.

If you have problems with the tightness of the glass, print the washers between the parts.
