The text appears to be a version update announcement for a 3D model project called "Submarine Kursk". Here's a breakdown of the content: **Version 1.5 Release** * This is a new release, v1.5, which marks the end of experimental proof-of-concept builds. * The previous version (v1.0) was also released on June 20th. * Version 1.5 comes in two flavors: RC-ready and Display-only. * RC-version has all interior parts for mounting electronics, while the Display version has these parts removed to save printing time and materials. **New Features** * Many more details have been added to the model. * The print and assembly process has been simplified. * Two versions are available to cater to different users. * Pre-split files make it possible to print the model on smaller build spaces. * Dimensions have been corrected to match the original Kursk submarine. * Gaps and thin walls have been fixed. * A PDF guide for assembling is provided. **Changes** * Servo mounts, pushrods, motor mounts, and electronics were tested. * Missile bay hatch mounting was fixed. * Fastening features for maintenance hatches were added. * Three propeller types are included to optimize thrust. * A stand for the model has been created. * .STEP file is provided for easier modification. **Print Instructions** * All plastic parts are printed from PLA, with 0.2mm layer height and 2 perimeters. * Slic3r automatic supports were used for RC version. * Watertight sealing is printed from NinjaFlex, with 1 perimeter and 100% infill. * Delta printers can print main hull parts as-is, while others may need to use pre-split files. **Assembly Instructions** * Drill holes to target diameter if necessary (rudder shaft, prop shafts, front plane shaft). * Insert rudder and prop shafts and seals into the rear hull. * Add bearings and gears for prop shafts. * Attach motor, servo, pushrod, and electronics. * Glue hull parts together with superglue and seal any open holes.
