MOTORISED YARD CRANE mk2

YARD CRANE mk2 This is an updated version. It's intended to be scenery for a model railway. I've printed it for my railway and the designs might be useful to others. Original version and photos at (https://www.thingiverse.com/thing:4749622). The design is intended to be motorised so that the crane rotates. I used a geared motor purchased from Amazon. A mounting plate for the motor is built into the design. It requires two tiny M1.6 (1.6mm) screws to hold it in place. The motor has a 6mm shaft which fits either into the turntable or directly into the crane. (see photo). The platform is compatible with my narrow gauge station at https://www.thingiverse.com/thing:4727163. FILES: - CraneOnBase - The entire design on a 'wooden' platform base. This prints as one. No supports, raft or brim required. Motorisation not possible with this one. - HandCrane - A basic crane design. (I'm not so pleased with this one). 3mm drilling in base to accept motor shaft. Print with brim. - motorCrane - A slightly better crane. 3mm drilling in base to accept motor shaft. Print with brim. (5 tiny supports have been incorporated that will need snipping off) - Platform - A wooden style base for the crane. Includes drillings to mount motor. - StonePlatform - A larger 'stone' structure intended to be stone blocks with slate infill. Includes drillings for motor mount and turntable. (https://www.thingiverse.com/thing:4749622). - Crane Plinth Wood - As 'Stone Platform' but mirrored and with an upper surface to simulate wooden planks. NOTES ON PRINTING The platforms do not require supports, raft or brim. The two cranes need a brim to improve adhesion. I printed at 210 °C with a 0.2 resolution. The crane jibs, being diagonals, require a bit of smoothing off. Any problems, please comment (politely) and I will attempt to modify. I sincerely hope other people will find these designs useful. Please post successful makes. DERIVATIVES: Another Thingiverse member has remixed the larger base to use a servo to turn the crane. https://www.thingiverse.com/thing:4881677
