Yellow Heavy Recovery Truck(MMRS) with Movements

thingiverse

The Multi-Mission Recovery System (MMRS) is a powerful vehicle designed to retrieve and repair disabled military vehicles in challenging environments. It boasts a 360-degree rotating boom with a 41-foot reach and impressive lifting capacity, handling even heavy armored vehicles. Its all-wheel drive and advanced suspension tackle tough terrain, while operator safety is prioritized with armored protection and remote controls.I am very thankful to Mr Benoît Lussier for his feedbacks which has helped me refine the model further.There are three ways to print this.As single piece:- Please download STL file but there wont be any movements.Multiple Pieces :- Download 3mf file with Full_dismantled.3mf.BEST QUALITY OUTPUT. Please use the 3mf file for assembly also. CHECK EASE OF PRINTING TITLE BELOWCombined:- You may use any 3D viewer software like 3D builder in windows to merge components according to your printer and filaments. The sky is the limit for this. You may find a sample file ending with combined.3mf.EASE OF PRINTINGThis model contains parts of 5 colours - YELLOW, GREY, BLACK, RED & WHITE. I have seperated these into different plates according to colour and in the optimum print position. Please download and extract the file “Print Plates According to Colour.zip” to make use of them. These plates can be opened in any slicer and printed according to your print profiles. Check the names of the files for the colour to print with. Print the wheel axles at minimum 60% infill DensityThe 14th and 15th Plates can be printed with filament change for the brand names on the top, if you choose so.It is recommended to print Plate 16 with PETG.ASSEMBLY OF MODELThis is done in 7 steps. Please follow the steps.ASSEMBLY OF UNDERCARRIAGEAttention:- There are three sizes of bolts used in undercarriage assembly. The bolt(2 in number) used for the tilt arm of the 2nd axle is the smallest ones. The bolts(2 in number) used at the ends of the front to rear axle counter link is the longest while rest are medium bolts. Ensure nominal movements( not too tight and not too loose) between the links for perfect working. You can either use a piece of filament or metal locking pins through the holes in the bolt to lock the links or you can glue to heads of the bolts to its counterpart. Gluing will work for all the joints except at the inter axle links. There you may have to you a metal lock pin or filament.ASSEMBLY OF TURRETASSEMBLY OF REAR PLATFORMASSEMBLY OF MIDDLE ELEVATORASSEMBLY OF FRONT PLATFORMASSEMBLY OF CABINMATING OF PARTSSTATIC DISPLAY LOCKINGThe are specific mechanisms provided by which various links can be locked in different poses. Please use a small piece of filament to lock the links as shown in the instructions belowMovements IncludedELEVATOR MOVEMENTS2.SYNCHRONIZING GEARSTURRET MOVEMENTSFRONT DUAL WITH REAR COUNTER STEERING NOTE The tolerances to some elements are zero which has been intentionally provided to friction lock the elements while not in movements. You may have to fine tune the tolerance from your end using scaling function in slicer to ensure good fit without compromising movements. This also applies for the pins that make rotation possible between elements. Please proceed with printing all the pins after testing printing a pin and testing the fit of a joint. You should be able to find the adequate scaling factor with this.The main body is made hollow to ensure filament savings.Supports should be provided as required.Appreciate the makes uploads. Open for suggestions.
