Brass Prep Station

thingiverse

Brass Prep Station, took what hcpookie did and remixed it/redesigned it. For the gear box plates, recommend a 20% infill and 3-4 perimeters or walls. For the gears (main helical gear and small helical gears), 4 perimeters and 70% infill plus 5 top and bottom layers. For the housing 2-3 perimeters and 20% infill is a-ok. For the tool posts, 4 perimeters. For the gear shafts, 4 perimeters. **note: The pics are not 100% complete, I was waiting on the motor and a few pieces of hardware** There are two gearboxes you can print: a 400RPM gearbox and a 250RPM gearbox I highly recommend the 250RPM gearbox as it is quite a bit higher in torque. Anything marked with a X6 you will need to print 6 of. This is the parts list needed: https://www.amazon.ca/gp/product/B071GTTSV3/ - 12v 200 RPM Greartisan style motor with 31mm bolt circumference. https://www.amazon.ca/gp/product/B09HV9HZQ6 - The bearings are 22OD X 8MM ID X 7MM thick skate board bearings, you need 12 of them. https://www.amazon.ca/gp/product/B08334N261/ - This the main gear hub for connecting the hub to the motor. You need 1 of these. https://www.amazon.ca/gp/product/B081YGD8LY/ - This is the fan I used, it is a 60x60mm x 15mm thick fan with a 50mm bolt offset pattern. It is a 12v fan. https://www.amazon.ca/gp/product/B07T1W7S1C/ - This is the power supply I used. 12v 2a power supply with adapter. The housing is designed specifically for this adapter to fit in to the case so it's plug and play. https://www.amazon.ca/gp/product/B083ZDFYKT/ - I used the m5 inserts out of this kit to bolt the gear box to the main housing. https://www.amazon.com/dp/B08P1SKYCB - I used these 8-32 brass inserts for the tool posts. The part number from EZ-LOK is FL-832-HI. The Switch is a 8mm X 14mm micro switch but you could modify the box to fit a bigger one if needed. You will also need: 6 - M3x0.5 thread pitch bolts for the motor. 4 - M3x0.5 thread pitch bolts coupler to main gear 4 - M3x0.5 thread pitch nuts for the coupler to main gear 4 - M5x0.8 thread pitch bolts to bolt the main housing to the gear box 3 - M5x0.8 x 40mm tapered head bolts to hold the gear housing together. 3 - M5x0.8 lock nuts The fan came with hardware for me but you'd posisbly need 4 bolts for that too. Happy printing
