Bell Super Visor Screw

thingiverse

Having lost a screw from the visor on my Bell Super helmet, I decided to replicate one including several options : A whole screw modeled in plastic, A "cap" for an M5 round head screw, and another version that allows am M5 screw to be bolted through. Print Settings Printer: XYZ Davinci Jr Rafts: No Supports: Yes Resolution: 0.1 mm Infill: Solid 90% Notes: For the whole plastic piece, I printed it with the thread pointing towards the print bed, using supports, in order to achieve a better print quality on the visible part. However, on PLA it didn´t stand much torque so the thread sheared off. The other two option require a little bit of fiddling to adapt the holes to the head of the screws. I intended to build them based on hex M5 screws, but couldn´t find any so I had to get the round ones. My favorite is the "capped" M5, as it retains the looks of the original part. Post-Printing The holes require a bit of rectifying to achieve the propper pressure to prevent the screw from dettaching. Screws are M5 x 10 How I Designed This Based on the original part from a Bell Super 2R helmet, Design in Autodesk Fusion 360.
