Beskrivelse

ISRO GSLV Mk II (GSLV-F17) 1:100 Scale Rocket with Magnetic Boosters & Launch Stand Celebrate India's space program with this highly detailed, mathematically exact 1:100 scale model of the ISRO GSLV Mk II (Geosynchronous Satellite Launch Vehicle) , specifically modeled after the GSLV-F17 mission. Standing over half a meter tall (51.7 cm / 20.4 inches) , this model was designed from the ground up in parametric CAD ( build123d ) to balance aerospace fidelity with effortless 3D printing. It features modular snap-together stages , satisfying magnetic booster docking , and authentic bilingual ISRO stencils . ✨ Key Features Precision 1:100 Scale : Total vehicle height: 515.5 mm (51.7 cm) matching the real 51.73 m flight vehicle (99.66% accuracy). Accurate stage diameters: 28 mm Core (S139/GS2) and 40 mm Payload Fairing (4.0m PLF). Magnetic Snap-Fit Boosters : All 4 L40 Liquid Strap-On Boosters snap onto the core stage using 5x2 mm Neodymium disc magnets . They attach firmly for display and pull off smoothly to demonstrate strap-on jettison! Modular Flight Staging : Every stage (S139 Core, Interstage 1/2, GS2 Liquid Stage, Interstage 2/3, CUS Cryogenic Stage, and 4.0m Ogive Fairing) connects with precision slip-fit collars (0.15 mm clearance). You can stage and un-stage the entire rocket. Authentic Multi-Color Liveries : Pre-modeled bilingual lettering: ISRO & INDIA alongside Devanagari इ स रो & भा र त . Twin red retro-rocket stripes on the GS2 stage. Debossed 12.0 × 8.0 mm (0.35 mm deep) pocket on the fairing barrel for the Indian National Flag (Tiranga) decal. Sriharikota SLP Mobile Launch Table : Includes a replica display pedestal inspired by the Second Launch Pad (SLP) at the Satish Dhawan Space Centre (SDSC SHAR). Production-Ready 8-Plate 3MF : Fully arranged and color-assigned for Bambu Lab X1-Carbon, P1S, A1, and OrcaSlicer multi-material printing. 📏 Technical Specifications Scale : 1:100 Total Height (Rocket) : 517.0 mm (51.7 cm / 20.4 in) Total Height (with Launch Pad) : 545.0 mm (54.5 cm / 21.5 in) Core Diameter : 28.0 mm (S139 Solid Core & GS2 Liquid Stage) Booster Diameter : 21.0 mm (L40 Liquid Strap-ons) Fairing Max Diameter : 40.0 mm (4.0m Payload Fairing) Booster Fin-to-Fin Span : 101.0 mm (10.1 cm) Estimated Filament Weight : ~320 g - 380 g PLA total Total Print Time : ~9 - 14 hours (depending on speed & plate batching) 🧰 Bill of Materials (BOM) / Hardware Required Item Specification Quantity Purpose Neodymium Disc Magnets 5 mm diameter × 2 mm thick (N52) 16 pcs 8 on Core Stage + 2 per Booster (4 boosters) Small Magnets (Optional) 3 mm diameter × 1 mm thick 4-8 pcs Launch stand hold-down shoes Adhesive Medium CA glue (Super glue) A few drops Securing magnets into pockets Double-Sided Craft Tape Thin clear 3M/Scotch tape Small strip Flag decal mounting Flag Decal Sheet High-res SVG / HTML printout 1 sheet Indian Flag for the fairing recess DIY Tie-Rods (Optional) Standard 1.75 mm filament 12 pcs (~35 mm ea) Inter-booster bridge links 🎨 Filament Color Guide & Plate Layout (8 Plates) The included gslv_mk2_master.3mf is pre-configured into 8 color-coded plates: Plate Name Colors / Filaments Parts Included 1 S139 Core Stage White (Slot 1) S139 Core White Barrel with upper magnet pads 2 GS2 Multi-Color White (Slot 1) + Red (Slot 3) GS2 fuselage + Red twin retro motors 3 4x L40 Boosters White (Slot 1) + Black (Slot 2) 4x L40 bodies with bilingual text & fin brackets 4 Dark Interstages Matte Black (Slot 2) Interstage 1/2 (lattice vents) + Interstage 2/3 5 Metallic Engines Metallic Grey / Silver (Slot 4) 1x S139 main nozzle + 4x Vikas booster nozzles 6 Red Launch Skirt ISRO Red (Slot 3) S139 aft thrust skirt & booster lower mount pads 7 Launch Mount Base Cement / Dark Slate Grey (Slot 5) Sriharikota SLP mobile launch display table 8 Fairing & CUS White (Slot 1) 4.0m Payload Fairing + CUS Stage with SOFI foam (Note: If printing without AMS / multi-material, all parts can be printed in single colors and assembled with glue or painted). ⚙️ Recommended Print Settings Layer Height : 0.16 mm or 0.20 mm (0.16 mm recommended for crisp stage collars and text). Walls / Perimeters : 3 walls (ensures strong slip-fit collars and rigid magnet sockets). Infill : 15% Gyroid or Grid . Supports : Rocket Stages & Fairing : NO supports needed (modeled with self-supporting angles and bridge geometry). S139 Main Nozzle : Support needed on the engine throat curve (tree supports recommended). Brim : Inner & Outer Brim (5 mm) recommended for the tall cylindrical stages (Core and Boosters) for bed adhesion. 🧲 Magnet Installation Guide (Very Important!) To ensure all 4 boosters can snap onto any of the 4 quadrants interchangeably: Establish a Reference Magnet : Pick one 5x2 mm magnet and mark one face with a black Sharpie (e.g., North Pole = Marked, South Pole = Unmarked). Core Stage Installation (8 Magnets) : Glue magnets into the 4 upper core pads and 4 lower red skirt pads with the MARKED side facing OUTWARD . Booster Installation (8 Magnets) : Glue magnets into the booster upper and lower strut pockets with the UNMARKED side facing OUTWARD . Test Before Glue Sets : Snap a booster to the core to ensure they attract rather than repel! ✂️ Indian Flag Decal Application The 4.0m fairing barrel includes a shallow debossed recess measuring 12.0 mm wide × 8.0 mm high × 0.35 mm deep (exact 3:2 statutory flag aspect ratio). Open indian_flag_print_sheet.html in your browser. Print at 100% Scale / Actual Size on a standard color printer (use the included 50 mm ruler on the sheet to verify scale). Pro-Tip : Apply a strip of thin clear double-sided craft tape to the back of the paper first , then cut out the flag with an X-Acto knife and metal ruler. Press the flag into the 0.35 mm recess—it will sit perfectly flush with the outer curved skin!
