Cap for Empty Propane/MAPP Cylinder - 4 Versions

prusaprinters

This cap is for small (net weight 14.1oz/400g) propane or MAPP gas cylinders which are empty. It is not safe (and in many places not legal) to simply dispose of these empty cylinders in the trash as they are considered hazardous waste. This leads to empty cylinders accumulating until they can be disposed of properly, which leads to the additional annoyance of being able to distinguish full containers from empty ones (not always easy as the full containers can lose their caps).While this is only a minor annoyance, it is also easy to 3D print a solution.This set of prints offers four options - a “minimal” cap (V6) and a “winged” cap (V5) - each with and without a printed label.  With the unlabeled versions, you can either add your own text with PrusaSlicer, or just use them as is for filled cylinders with a missing cap, partially used cylinders, etc.Print InstructionsPrint in PLA in two colors (via filament switching) using the 3mf files provided; otherwise :0.3mm layer height2 perimeters5% rectlinear infillNote 1 : The STL files have a built in “brim” to improve bed adhesion - remove this brim after printing.Note 2 : I did not actually print either of the “blank” versions, but as they are identical except for text to the labeled versions I assume they will print just as well.CADThe OnShape 3D CAD files for this are here :https://cad.onshape.com/documents/02261ff9903e93fc81aa0bd5/w/3209e2fe910f92168b089898/e/d1637f8270d33ef2cc3c17fe?renderMode=0&uiState=659b19d12e32b82d95586568
