Parametric Enclosure based on Openbuilds Modular Enclosure System

thingiverse

10/17/2020 Update In **Enclosure_Rev9.scad** added option for 2020, 2040 or 2060 Door headers since Openbuilds changed their design to use 2060 for the door header. For smaller enclosures you might not need that, so added the 3 options. For this option set: **Hd_Size = 60; //20, 40 or 60** Also added option for 3 or 4 joining plates on the door. For this option set: **JP_Qty = 4; //Set to 3 or 4** The spreadsheet **VariableModular_Enclosure_V3.xlsx** was also updated by adding the variable line: Door Header Z Height Size (20, 40 or 60) This really only affects the cut lengths of Door Vertical Lengths & Door panels. This is a parametric openscad program to show different size configurations of the Openbuilds Enclosure system which can be found here: https://openbuilds.com/builds/openbuilds-enclosure-series.9535/ There is also a spreadsheet that will give you all the cut sizes. The calculations used here are based on their 3 different configurations & I have not created an enclosure yet, so be aware that there could still be bugs here. That said, the cut size numbers come out correctly for the 3 different sizes Openbuilds sells. I would like to make my enclosure a little different size that can be used on more than one machine since I will not be using the different machines at the same time. I think Openbuilds is using 1/4" boards for the sides, top & back panels, but I am thinking of just using 20x30" sheets of foam core to start with since they are only $1 each at dollar store. Using the enclosure spreadsheet if I set the Overall Length & Width to 794(mm) & Overall Height to 540(mm), I can use 20x30 foam core panels without cutting them. The top panel would be 30x30 though, so it would need a partial foam core added with the 20x30. Foam core would also might it lighter than using wood. The door gaps I based on the 3D model of the hinges being 20.4mm between the V-Slot holes, so the side gaps are 0.4mm. The gap between the door panels I calculated based on what openbuilds had for the horizontal lengths of the Door V-Slot extrusions. This openscad & spreadsheet file uses the 3 way brackets for the corners by default, but if you want to use the 20mm cube corners, change the variable in openscad file to **Br_Thk** to 20 instead of 5 (or spreadsheet line **3 way Bracket Thickness**) This openscad file uses the following STL files in the model: **InHidCornBr.stl**, **V-Slot_DrHandle.stl** & **Hinge.stl**. These files were converted from Openbuilds 3d models. The other parts of the openscad assembly are modules in the file.
