Printed Parts - Githubissues

Design changes needed in the printed parts are:

X Axis

Y Axis

[x] Y-Front Right: more space for idlerbearing axis: make it with a dowel pin.
[ ] Change bed leveling mechanism (no de-adjusting during printing).
[ ] Prepare for IGUS Bearings
[ ] Rubber feet in all 4 corners + Z motors holders.
[x] Make Y corners more round
[x] Y-Teeth: Print in ABS
[x] Y-Teeth: Fix withPlastic screws (Change frame as well!)
[x] Y Front - mounting hole should be the M4 mounting hole on the side and not the m3 PCB hole on the bottom
[x] Y-Beltholder - magnet support bumps into the power supply
[x] Y-Beltholder - no room for zipties to secure the belt; use a double set of teeth??
[x] Y-Motor - The belt tension causes unstraightness and probably squeeky sounds
[x] Power Supply - Up side down
[x] knobs for bed leveling smaller, and spiral shape to make clear which direction is up and down.
[x] test several springs for the hotbed
[x] Third screw for Y-Motor to keep it straight
[x] Left and Right marks for middle PSU holders
[x] More convenient Y Endstop cable assembly
[x] Mechanism to adjust the Y-motion parallel
[ ] Vibration Isolation from the Y-Rods

Z Axis

[ ] Right ACME seems to be unstraight
[ ] Integrate bearing holder into one part.
[x] Z-Top: Thin wall to hide the screw
[x] Z-Top: Inner radius
[x] Z-EndstopHolder: Change it
[x] Bottom Z - bridge for the motor screw holes instead of tiny breakout supports (done 19-9 BdV)
[x] Bottom Z - The clamps for the rods need extra support for printing, now it´s a bit ugly (done 19-9 BdV)
[x] Bottom Z - The holder on the right needs a little slit for the Z endstop wire to go through
[x] M5 Tops - They are a bit too low
[x] Anti wobble - Lower the Z-Bottom parts, so the printer only stands on the front and the back and never wobbles.
[x] Z Endstop doesn´t fit for the first 8 plates due to bad milling
[x] Z-Endstop to the back for more adjustment freedom
[x] Plastic nut with anti backlash or ball spindle (ACME rods are sufficient)

Extruder

[ ] Slide in radial fan (no more screws).
[ ] E3D fanholder: Same on both sides
[x] ExtruderCenterPiece: Take of little edge of the center piece to avoid collision with screw of filament pulley
[x] ExtruderCenterPiece: Add little edge in cable channel, to avoid cable clamping between aluminium
[ ] ActiveCoolingDuct: better design for better cooling
[x] Active cooling
[ ] Light on the nozzle
[ ] Ready for 3mm, test also with flex materials
[x] Direct drive extruder, lower the extruder to increase built volume.

Casing and rest

[x] Update for small endstop
[x] SpoolHolder: more distance 5mm
[x] SpoolHolder: Round it up
[ ] RumbaCaseBottom: Better cable inlet holes
[ ] RumbaCaseBottom: Some hooks on the inside
[ ] PowerSupplyCover: Fitting to the new power supply.
[ ] PowerSupplyCover: Fix with screw
[ ] PowerSupplyCover: Seperate cable entry
[x] PowerConnectorCover: Better entry for the cable
[x] PowerConnectorCover: Fix with plastic screw. (change alu plate as well!)
[x] PowerConnectorCover: Better holding the ring + teeth washer
[x] PowerConnectorCover: Better clamping of the power connector.
[ ] Display knob redesign
[ ] All screws Torx
[x] Display casing: better support for button pushing
[x] Display casing: better mounting to frame with anvil for clear end.
[x] Display casing: knob
[x] Lower aluminium frame for better passing of power cables
[ ] Bowden tube - would be nice to have a bowden to guide the filament. Can only work if the extruder part has some hole to keep the tube in place
[x] Ask Gemmel for less rusty rods. Answer: Rods can rust.
[x] Extruder moves a bit when extruding
[x] Spoolholder as a tool to screw in M5 threaded rods
[x] Nicer holes for endstop covers
[x] Idler for the extruder doesn´t quite fit
[x] Power Cable with connection
[x] Ground leech for machine safety
[x] Nice box for shipping kits
[x] Use plastic screws
