This is a snap together design to print your own window grid.
Parts are divided to easily fit on your printer bed.
Use the parameters to configure to match your window size.
I originally designed this to make window frames for my tardis.
Instructions:
If you want dovetails, download JointSCAD and place in your working folder. https://github.com/HopefulLlama/JointSCAD
Enter your window dimensions and parameters below.
Horizontal measurement of opening
Vertical measurement of opening
Number of Panels in each row
Number of Panels in each column
Export stl and use your slicer to divide into individual objects to print.
In PrusaSlicer, click the "Split to Objects" button. (not the Split to Parts button).
Press the A key to arrange parts to best fit your bed.
Print your first tray, then delete the printed parts, and press A again to arrange the remaining parts to print.
Assembling, the joint fits are tight. Use a hammer to lightly tap the parts together.
Only the outer frame parts use joints. The inner parts need super glue.
Fast Draft Print Settings:
These speed settings reduce my print times by half and still print flawless shapes. The only thing I turned down the speed on was the First Layer Speed to 30 mm/s (default).
