Tarmo5 cover / body skull and wing

prusaprinters

Tarmo5 is a great project by Engineering Nonsense. → this model was originaly posted here : https://www.printables.com/fr/model/424220-tarmo5-mods-reinforce-all-the-frequently-breaking-  but I decided to split it  in 2 pages as it was too long to read. So all the comments are on the other page.The wing and body→ updated on 2023/04/23: added GEARBOX_w-SKULL_-_B02 reinforced (see bellow)→ updated on 2023/03/21The wing was originaly published by cleosynthesis in Tarmo4 rear wing, body cover and body/wing holder. I designed 3 different ways to attach it to the tarmo5 so you can choose how you want to attached the wing:In my pictures: red wing holder= v1, gray wing holder= v2 integrated to gearbox, black TPU holder = v3If you read this page for the first time, you can directly jump to V3 section below.V1 : The skull was initialy published by flyntm (see remixed). I use his parts to attach the skull. I designed Wing_holder v1 to attach the wing. Just attach it to the "shock mount A01" replacing the 3 M4 screws by longer ones.Files to useTarmo_Rear_WingWing_holder v1GEARBOX_w-SKULL_-_B02-FM-ReinforcedLT → see bellow why a reinforced versionthe skull from flyntm (see my reinforced front version of the skull here)V2 :Why this new design? I added a back bumper designed by flyntm in Tarmo5 Enclosed Gearbox. If you also want to use the back bumper, you will need (from flyntm's page) :GEARBOX LID Bumper - B01-FM.stlBack Bumper - B15-T-FM.stlthe skull (see my reinforced front version of the skull here)And from this page:GEARBOX B02 Wing_and_body_holder v2Tarmo_Rear_WingMy wing was longer behind than the back bumper. So needed to move the wing forward in order to be protected by the bumper in case of back collision. I also moved the wing a bit down, I think it looks nicer. In this design the GEARBOX is modified to hold the skull and the wing. V3 → added on 2023/03/21Why this new design? my son just crashed the car full speed on a concrete wall. And the car frequently finished its course upside down.The car is very strong so the structure is fine. Damages parts: wing holder, skull front holder, skull. I temporarly repaired with epoxy and a piece of metal inside the broken wing holder. I also added a spring, a washer and a longer screw to the front attach of the skull but I was not really satisfied. When the car crashed upside down I need more flexibility to protect the skull and also if one of the attach point breaks, I want to just replace the piece without having to disassemble the whole car. So I decided to separate the holder from the car structure. The first on beeing in TPU for flexibility and skull protection, and the second in PLA.Files to use:END CHASSIS - B05 - for TPU skull holderTPU front skull mount v3GEARBOX_w-SKULL_-_B02-FM-ReinforcedLT → see bellow why a reinforced versionTarmo_Rear_WingWing mount v3.3mfthe skull from flyntm (see my reinforced front version of the skull here)I'm very satisfied with the result. I came back to the gearbox from flyntm and designed a TPU holder coming on top and attached with the 3 screws of the back SHOCK MOUNT (replaced with 50mm M4 screws).In front I modified the END CHASSIS B05 to add 2 holes for M3 screws on the sides to firmly maintain my TPU holder additionaly to 3 longer M4 screws for the front SHOCK MOUNT.I use M3 metal insert in the TPU for the front skull attach.See the pictures (my TPU is black). The result is flexible (TPU print with 2 walls, 10% infill), stonger and modular, so in case of broken piece, it's very easy to replace.→ in the comments of my original page @summons shows nice pictures of his TPU print of this body. That's a great idea and it seems to work perfectly. However as my son never managed to break the body printed in basic PLA I did not try it. Added on 23/04/22 :SKULL REINFORCEMENT:My kids broke many times the front part of the skull and I published a reinforced version here :https://www.printables.com/fr/model/459407-tarmo5-skull-body-reinforced-without-or-with-fpv-cGEARBOX_w-SKULL REINFORCEMENT:I also broke the GEARBOX_w-SKULL that is used in v1 and v3 to attach the skull to the TARMO5. The walls on the sides of the 3 bolts that hold the 35cm rods are very thins and broke. The version attached here is reinforced. You can find a .stl with reinforcement very small but enough if you print with many walls.I also included a .3mf file where I add many perimeters and infill in the weak parts. If you use directly the .stl file, please take care to add 8 walls in the weak part. PRINTING PARAMETERS TO MAKE STRONGER PARTS:My 3 sons ofter destroy things and I use my printer every day. It gives me the chance to test new printing settings and compare everyday small changes on the settings.As I was asked to, I share my conclusions and prusa slicer settings at the end of this page:https://www.printables.com/fr/model/424220-tarmo5-mods-reinforce-all-the-frequently-breaking-
