Speedloader for S&W 627 Target Champion

thingiverse

Made specifically for the S&W 627 Target Champion, old model (627-1) 6 shot, hole circle diameter 27.85 mm. For those not familiar with metric measurements: this translates to a circle of 1.096 inches in diameter. To ensure a perfect fit, it's crucial that you scale your model by either adding or subtracting 0.1 or 0.2mm from the total size, depending on your printer's capabilities. Please share pictures if you manage to print one or several of these models. For accurate measurement of the hole circle, we recommend using two identical cartridges placed in opposite positions and then rotating the cylinder so that the cartridge bases are between a caliper. Take note of the maximum value recorded, then subtract the diameter of one cartridge base from this figure. Available versions include: V.02 offers a smooth transition between different stages of cartridge holders. The _27.70 version boasts a hole circle measuring 27.70mm in diameter (1.091 inches). horizontal_B is designed with openings that face upwards to prevent support layers from obstructing the cartridge holders (this simplifies life for users whose printers can read .stl files directly). _loose has a more relaxed fit, increasing the dimensions of the cartridge holder by 0.2mm. Print Settings: Rafts: Yes Supports: Yes Resolution: Minimum 0.25mm required Infill: At least 10% recommended Notes: Dimensional accuracy is paramount; other considerations are relatively unimportant. The model shown was printed on a Chinese machine with known mechanical limitations, using PLA material, 0.25mm layer height, 0.4mm nozzle size, and print/travel speeds of 80mm/s. Rafts and supports were employed during printing.
