Prusa i3 steel 10mm upgrade

thingiverse

I wanted to upgrade the 8mm bars on my Prusa i3 steel printer but couldn't find any parts that I was happy with so I designed this set to use 10mm 303 stainless steel bars and Oilite bushes as these are quieter than the linear bearings commonly used. The full set of parts which will comprise both X-axis ends, the carriage, the x-axis servo motor mount, cable chain anchors and various ancillary parts. 3mm cap screws and nuts are used for assembly. Other components needed include: a 5mm steel rod for the x-axis belt pulley a bearing equipped idler pulley http://www.ebay.co.uk/itm/152174444568 2x 10mm 303 stainless steel rods 500mm long (for the X-axis). I drilled and tapped each of the ends for a 3mm cap screw 2x 10mm 303 stainless steel rods 330mm long (for the Z-axis vertical rods) - I machined each end of each rod down to 8mm diameter so that I didn't have to drill the steel plates on the Prusa frame. You could drill the frame if you don't have a lathe 2x microswitch limit switches. (1 for left X-carriage and 1 for lower end of Z-axis) Other parts designed for my printers include: http://www.thingiverse.com/thing:1959901 (GT2 belt clamp (Prusa Y-axis) http://www.thingiverse.com/thing:1937232 (Arduino Mega and RAMPS v1.4 case) http://www.thingiverse.com/thing:1905409 (Prusa i3 steel 10mm upgrade) http://www.thingiverse.com/thing:1959974 (Prusa i3 Steel Y-axis motor mount) http://www.thingiverse.com/thing:1991116 (Prusa i3 Steel X-carriage) http://www.thingiverse.com/thing:1991117 (E3D Chimera / Cyclops mount) http://www.thingiverse.com/thing:1994413 (dual E3D Thermocouple amplifier board - housing) http://www.thingiverse.com/thing:1090661 (Belt driven Bowden extruder with 1:2.5 reduction) http://www.thingiverse.com/thing:896676 (enclosure for SevenSwitch FET) http://www.thingiverse.com/thing:922455 (8mm Z-axis leadscrew bearing holder) http://www.thingiverse.com/thing:922309 (Z-axis NEMA 17 adjustable endstop bracket) http://www.thingiverse.com/thing:899607 (cable chain) https://www.thingiverse.com/thing:2334269 (LCD housing) https://www.thingiverse.com/thing:2377049 (PSU cover) https://www.thingiverse.com/thing:2395715 (Chimera & Zesty Nimble drive cable spacer) https://www.thingiverse.com/thing:2407651 (Chimera Zesty Nimble X-axis set for i3 clone) https://www.thingiverse.com/thing:2436869 (A dummy NEMA 17 motor to hold the 5mm shaft) https://www.thingiverse.com/thing:2748978 (A Duet WiFi housing) https://www.thingiverse.com/thing:2749324 (A layer fan for the Smart Effector) https://www.thingiverse.com/thing:2814068 (A Sannce I21AG mount for 3D printers) https://www.thingiverse.com/thing:2844881 (A cooling duct for a Noctua 40mm fan on a Duet Smart Effector) https://www.thingiverse.com/thing:2846955 (A quiet BerdAir type pump mount) https://www.thingiverse.com/thing:3333609 (A Raspberry Pi case with 40mm fan) For avoidance of doubt, this item is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
