Another Day, Another Funnel

Needed one at work now...

Coffee Funnel

A request to make another funnel, slightly larger diameter:

Peppercorn Problem

Always found it annoying filling up the pepper mill, and a normal funnel has a too small opening.

Two cylinders, a cone and the shell tool later:

Clothes Basket Fix

Clothes baskets can be poorly designed and crumple when held with one hand.  This reinforces the problem area, simply held on with zip-ties.

Used a honeycomb fill pattern for extra strength.

Filament Spool Holder

Got some cheap PLA filament on eBay...

...so now I need to make a spool holder.

Version 1

 I found this design on Thingiverse:

I found cheap roller-door rollers with bearings at Bunnings for $5.14 each.  I wanted real bearings, rather than 3D printing a solution.  You don't want filament feeding problems.

Printed a copy:

Problems:

• Side walls too thin. cracked on a slight flex.
• Had some warping from uneven cooling.
• My roller wheels were 1mm to wide (oops).

Researching warping, best preventative strategies are:

• Avoid cold draughts.
• Clean all surfaces with Isopropyl Alcohol to remove grease.  It also makes the blue painter's tape super-adhesive to the plastic.
• Can slice up the object using skirt and brim settings to attach the skirt to the object.

Version 2

Decided to make my own.  Removed most of the vertical wall material, and made the vertical walls much thicker.  I had some perfect sized M5 bolts.  I printed some bushings because The bearing diameter is 6mm, and this way I can tighten up the nut onto the bushing and not the bearing.

Print number two resulted in a fail half way through.

Investigation found my first 3D printer jam.  If only I had some device to help feed the filament in smoothly...  I also adjusted the extruder spring tension off a little bit in case there was too much force applied.

Print number 3 finally working and assembled.

Printrboard Mount

The control board for the Printrbot just screws into the plywood frame, and ends up sitting on a bunch of zip-ties.  A fairly terrible design, and there are cables going everywhere.  To fix this a Printrboard mount and cable management solution is required.

Part 1 - Printrboard Mount

Design in Autodesk 123D Design, and model the height of all the plugs so we can print something for the cable management too.

Start with 2D layout.

Added plug height.

Mount with riser for cable ties.

Dividing up for printing.

Printed.

 

Fan Shroud

The second thing to print is the Printrbot Fan Shroud, to improve the cooling efficiency of the fan.

After the previous failure, I decided to use the pre-sliced version to see if that was the problem.  The first few attempts had print nozzle crashes into the bed, and calibration wasn't working.

On a thorough examination, I found that one of the bolts holding down the aluminium print bed had not threaded properly through both pieces of plywood.  As a result the wood had separated with a 5mm gap.

Problem Fixed, recalibrate, reprint, success.
