"A team of scientists has published a study that details the health hazards of 3D printing in enclosed spaces, which it says causes the release of toxic and carcinogenic particles." For this reason, it is recommended to keep 3D printers in a well-ventelated environment. The same can be said for laser cutters as dangerous gasses can be expelled from the machine when cutting Synthetic polymers such as; plastics like polyethylene, polycarbonate, polypropylene, as well as synthetic rubber, polyvinyl chloride (PVC), polyethylene, phosgene and many other materials.

| Reliablilty |
Medium - one support on each motor shaft, each being ridgid and made of a UV withstanding plastic that melts at higher tempratures to other platics. The reliability is however let down by only one support per side of the drone. The part is made this way on purpose in order to be a sacrificial and cheap part and thus reliability isn't as huge issue as it still protects the drone. |
High - The landing feet use two seperate support shafts for reliability in case one snaps. The spacing in between the two supports allows for the part to bend more easily and absorb impact energy and be more reliable for repetitive use on multiple crashes. |
High - the hollow body allows for better flex upon impact and the strong shell and cross bracing used on the parts adds reliability to the product. |
High - the alumnium frame covered in Carbon-Fibre Vinyl makes for a strong part that is resistant to scratches and less servear crashes. The two supports that come down from the main frame don't offer stability on unflat surfaces due to the leg layout but are reliable in terms of strength. |
Very Low - Cable covers not suppose to be used as springs or have a verticle force applied on them. The connection of likely hot glue is also poor and easily breaks off when put on smooth surfaces of injection molded or extruded parts. |
High - Connects at three diffrent places per set of two legs. The legs are made of rigid plastic, each connection point connecting to a seperate frame section, leading back to the drone chasis. |

| Reliablilty |
High - - Low reliability plastic that snaps easily under load due to thin amounts of material used. Features many supports to hold frame/box around the blades adding redundancy in the same one of the flimsey plastic parts was to break |
Medium - Two thick support beams holding up guard like portector but features being snapable due to lack of internal supports stopping the part from crumbling under load. |
Low - two flimsy plastic extruded rods are used to drop the guard from pressing in and they could easily snap under pressure. |
Extremely Low - One spport used means a lack in relaibility when it on an angle which will likely snap the part and damage the blade. |
High - two thick rods bent to stop direct contacts to the wall that will likely end in damage. |
Medium - Two thick support beams holding up guard like portector but features being snapable due to lack of internal supports stopping the part from crumbling under load. |
Medium - Three thick support beams holding up guard like portector. This part is harder to snap due to an internal supports stopping the part from crumbling under load. |
