Window Screen

thingiverse

My current residence lacks window screens or any means to allow a cool breeze to flow through the house. As a tenant, I'm restricted from making modifications without approval and the associated costs would be prohibitive. To address this issue, I developed a window screen that can sit in the window sill while still allowing the window to remain open. This design effectively keeps bugs and critters out while permitting the evening breeze to circulate. This screen is based on six components: interconnecting keys of two different lengths, end pieces (left & right), mesh windows, and middle pieces. The end and middle pieces are 1/16" taller than the window pieces to accommodate the weight of the physical window. I added weather stripping across the top of the mesh windows to cover this gap and prevent any bugs from entering. The mesh is printed in place by pausing the print on the middle layer of the frame. It's crucial that the preceding layers where the netting is placed are solid infill/layer, otherwise when you peel the print off the bed, it may de-laminate. Physical Design: The internal dimensions of my physical window were 39.75", and these components' design was based on this information. However, I designed the whole assembly to be 39.625" to allow for expansion/ease of insertion. You will need to scale your components accordingly. Mesh screens: 6" tall and 9" long, with a channel for the key that's 1.5" long End pieces: 6.0625" tall and 1" wide, with a channel for the key that's 0.75" long Middle piece: 6.0625" tall and 1.625" wide Keys: 0.24" x 0.24" The code I used to pause at the desired layer is as follows: G92 E0.0 G1 E-3 F3600 G1 X0.000 Y200.000 E0; parking position M17; turn on steppers* M104 S0; set extruder temp to 0 M140 S0; set bed temp to 0 M1 PAUSED; stop and print message G28 X Y; home X and Y* M190 S75 ; set & wait for bed temp M109 S255 ; set & wait for extruder temp G1 E3 F3600 G92 E0.0 Assembly: - Use the 2.5" key to connect the mesh window to end/middle pieces. - Use the 3" key to connect mesh window to mesh window. - Place super glue in joints, insert key, then push and hold connecting pieces together. - Place weather stripping across the top of the mesh window.
