Fixed couplers 4mm/8mm

thingiverse

Here is the rewritten text in American English: A Simple Fixed-Style Coupler for 4mm Motor Shaft to 8mm Threaded Rods. I designed this coupler to compare the effectiveness of a non-flexible design against traditional aluminum flexible ones. The results are impressive, and I find that it works better and reduces wobble significantly when paired with an anti-wobble device (see Thingiverse: Anti-Wobble Coupler). Required Hardware: * 4 M3 Nuts * 4 M3 x 16mm Screws or M3 x 20mm Screws Printing Instructions: 1. Print the parts in a vertical orientation, as shown in the photo. 2. Printer Settings: * Brand: RepRap * Model: Prusa i3 * Raft: Yes * Supports: No * Resolution: 0.2 layer height and 0.3 nozzle diameter * Infill: 20% Notes: This design is printable without supports due to its small base size. To ensure proper adhesion, I recommend printing with a raft, which yields excellent results.
