Fully parametric box/container.

edit 24.03.2013: Added version for Customizer. If you need more option download the file "box_openscad_files_with_examples.zip" and use with OpenSCAD.

Just a simple box to put in things.

Size: 124mm x 64mm x 43mm

The mendel-parts.com V9 1,75mm Hotend/Extruder works reliable as it is, but it has some downsides.

It uses a brass drive gear which is not very reliable. If the filaments runs out or snaps the teeth of the brass drive gear touch the hardened steel surface of the bearing and become dull.

Also filament change is complicated and time consuming. It is often necessary to disassemble the screws that hold the springs if you don't have 3 hands. ;-)

The MK7 Drive Gear is a useful upgrade. It has a better grip on the filament, is made from stainless steel and makes filament change easy.

The enhanced driveholder guides the filament more reliable and can be fixed down to the lower aluminum plate to increase stability.

To fit the MK7 Drive Gear on an V9 Extruder some modifications are necessary:

The old Gen6 electronics isn't able to switch off the print bed heating after your print is done.

This upgrade enables the printer to switch off the print bed heating by its own:

The mendel-parts.com V9 1,75mm Hotend/Extruder works reliable with PLA.

Unfortunately 1,75mm ABS filament is softer and more flexible, which can cause some problems.

Sometimes the filament bends before entering the hotend tube and curls up between filament drive and hotend.

This upgrade solves that problem.

UPDATE May-2013, version V3 GT2:

- changed the design to fit GT2 belts
- greatly improved belt holder stability
- improved lm8uu holder

The original design didn't work on all bottles. It slipped on some very tight caps. I just copy&pasted two together, one rotated by 30°. Now it has twice as much teeth.

Unfortunately it is also more difficult to put it on the bottle cap.

If the original Plastic Cap Wrench slips on your bottle, you may have more success with this one.

I changed the top corner so that two 624 bearing can be used, to minimize friction.

Update: I've used this now for several prints and it isn't as useful as i thought. Without friction the spool swings to much which can cause the filament to become tangled. I don't recommend using this modification anymore.

Mount for an 40mm cooling fan. Fits on an Orca v 0.2 with V9 Hotend.

Improves print quality, especially when printing thin walled objects.

The mount is designed for a 40mm fan with 4mm holes and a hole spacing of 32mm.

Consist of:
- a fan mount,
- a funnel to guide the air directly below the hotend nozzle
- a fan grill to protect the fan


Without the funnel the fan will blow to much air against the hotend, so that it may fail to reach more than 205 °C, with the funnel it may still be necessary to raise the hotend temperature by 3-5°C. (I use 213°C for PLA).

A higher heatbed voltage may also be necessary. (I use 19 V for PLA)

I'm not entirely happy with the funnel geometry, comments/suggestions are appreciated.
