Waterproof Housing

thingiverse

This is a parametric rectangular, waterproof housing made with openscad. There are two files: housing.scad is the module which contains the logic and housing_example.scad is the file with parameters. Included is also an example file in stl format with an inner size of 75 x 130 x 25 mm. The images included are made from a modified version with already holes and a dovetail joint (https://www.thingiverse.com/thing:3148124). To be waterproof, there must be a gasket in the form of a rubber ring, which can be found in office supply stores. For the example, the rubber ring should have a 1.5mm thickness and 396mm total length (better choose a little shorter). You need four water-resistant screws 3.0mm x 16mm for the example. Printing information: Open the housing_example.scad in openscad. Important: Preview doesn't show everything correct due to complex structure. Press F6 in openscad to render it. The variable names should be rather self-explanatory. The inner size does not include screw sockets, so available volume is a bit smaller. The dimensions of the rubber gasket are printed in console output of openscad. The tolerances and gaps should be fine for calibrated printer. You can switch on and off bottom/top part and choose arrangement of both: side next to each other, fit closed, demo above each other, overlap both in origin. Slicer settings: This is not very complicated to print, but big surface might make bed adhesion at corners problematic. I was using ASA as material and Cura as slicer and these settings (beside my standard profile): Build plate adhesion type: brim Wall line count: 8 Top/bottom thickness: 0.8 Bottom thickness: 0.8 Infill density: 100% Optimize wall printing order: yes Additional Information: * ASA is sturdier than PLA and UV-Proof for outdoor use, but more difficult to print. * Don't tighten screws too much; the groove between top and bottom part should be constant along sides. * No guarantee on waterproof performance! The area around groove for rubber should be perfect. * Use clothes pegs for fiddling in rubber ring
