- Upgraded bearing size, roller chamber and rod size dimensions.
- Zero/minimal clearance internals for maximum accuracy.
- Clamps redesigned to improve rod stability and to prevent binding.
- Inner and Outer Spacers added!
-
Flange body mount retained as accessory or mounting option for Horizontal X-Axis Carriage.
- Compact body option added without flange to reduce material inputs!
- Design modified to improve printing outcomes, safety, production cost and adaptability.
- There will be some gap between the mounting and front body when assembled.
Compatibility:
- Prusa i3 4 Bolt X-Carriage (Wilson TS and other RepRap derivatives)
- Prusa i3 Vanilla 3 Bolt X-Carriage (Wilson TS and other RepRap derivatives). Note that only two bolts will likely connect for this release. Second mount file after it’s been prototyped!
- Other machines with flange body, modification and or mounting adapter.
BOM:
Printed Parts:
- (1) PCB Holder Body
- (1) PCB Holder Front Body
- (2) PCB Holder Clamps
- (4) PCB Outer Spacers
- (2) PCB Inner Spacers
Hardware: - (4) 625 roller bearings
- (1) 8mm (dia) x 125-150mm steel rod that is very very sharp at one end
- (1+) Very healthy rubber band
- (?) Hardware unknown: M3 and M5 bolts, washers and compatible nuts hold it together!
— (4) M5x35mm Hex Cap Machine Screws/Bolts and Nuts
— (4) M4x50-60mm Machine Screws/Bolts and Nuts
— (2) M3x8mm Machine Screws/Bolts
— (8+) 8mm I.D. Washers/Precision Shims
Estimated print time for all components (flange mount body) is 2hrs 51min, 7.56m/65g at 25% infill. Less for the non-flanged.
Props to the original Norwegian designer Arvid M. who created this for the K8200! It was initially somewhat difficult to sort out specifically how he put it together, but it’s a brilliant, simple and functional design! For his ‘instructions’, details, design inspiration and FreePCB instructions please see his original post here: http://www.lamja.com/?p=635 and associated YouTube videos. Be aware that I have modified the design to take larger bearings and potentially a larger rod than the original source files REMIXED FROM (direct download link):
