Wow! 446 downloads for version 4 and version 5!

The old versions have been removed and you can now download and print version 6 for your Ramps 1.4 or Printrboard electronics.

Use this mounting plate to mount your electronics to your reprap prusa mendel. If you want to mount your electronics on the front left or rear right, you'll need to download the "right" file. If you want to mount it to the front right or rear left, you'll need to download the "left" file.

Lately, there have been a lot of spool holders posted on Thingiverse. I promised others on Thingiverse that I'd post this last week. It's been stress-tested for several months now and is ready for primetime.

Here is the second version of my original filament spool system with significant advantages. First, it's 100% printable. No hardware is needed for either the mount or the actual spool! The entire spool and mounting hardware can be printed on a Cupcake / ToM from only two .stl plates, and only four prints. Its standard size is ideal for 1lb rolls of plastic and has been tested with ultimaker and MBI rolls. Even if you order 5 lb rolls, unless you print constantly, you probably should cut it into smaller bundles since the hydrophilic plastic will absorb moisture.

The spool mounts to the side of the Cupcake (I don't have a ToM but expect it would work too) with friction-fit clips. A PTFE tube to act as a guide for the filament is optional but recommended (I have successfully printed about 3 lbs of plastic both with, and without, the guide tube). The spindle can be removed by squeezing the bird's mouth tabs on the end of the spindle post and pulling the hub off. The hub and filament can be placed into a plastic bag (without removing the filament) to allow it to remain dry when not printing). The hooks that hold the filament have clips that hold the tail end of your filament (to prevent the filament from tangling) and to clip the working end when it's removed for storage.

The design is almost fully parametric, so you can print different sized hubs and clips for different spool diameters and filament sizes (I've tried 3mm and 1.75mm).

I originally used bearings on the hub but found that it is TOO low of friction, causing the spool to free-run and spooling off too much plastic. Although you can use bearings, some tension is necessary. The spindle post includes code to print a spring tensioner as shown in the photos.

The stl's can be printed as is, but if you want to make parametric designs from the OpenSCAD file, also download Libs.scad from thingiverse.com/thing:6021 as it has required modules.

Procedurally-generated panpipes for 3D printing. They really whistle, but they aren't particularly accurately tuned. OpenSCAD file included.

It'll theoretically play a chromatic scale (12 notes to the octave) but it's too squeaky to know for sure!

I decided to revive the venerable iris box by redesigning it in OpenSCAD and making it printable with fewer parts and less assembly. It's also somewhat larger (though now the dimensions are easily adjustable with OpenSCAD), the tracks are redesigned to give more rigidity when closed, and it now opens and closes according to righty-tighty, lefty-loosey. The ring is also aesthetically redesigned and the base interior tapers down the wall thickness to give a little more internal volume.

The "lightbulb" is a 5-sided spiral that forms the general shape of a lightbulb. I made this a few years ago as a test piece and I've updated it just for you.

I've included two sizes:

Full size: about 4.8 inches tall
Half size: about 2.4 inches tall (...yep, that's half...check!)

I've also included each STL file in two resolutions.

This is derived from nopheads Mendel Pulley with captive M3 nut, but has been redrawn in openscad, and added more nuts for extra grip.

I'm sitting here looking at my printer, thinking "why are there three separate parts there?"

Note: pictured model is sized for M6 threaded rods!


I've seen a few similar designs but I couldn't find them when I went to look, so I made this one myself from prusa's 'felt' Z motor mount.

Unlike prusa's felt mount, this one won't print vertically due to the bar clamp!

This eliminates the need for: 4x M3 nylock nuts, 4x M3 washers, 4x M3 screws, 4x M8 washers and 2x M8 nuts; total 20 fewer vitamins.

***UPDATED 9 November***
Replaced with scad that defaults to standard frame rod spacing, and an STL that has M8 holes rather than M6

This is a forced cooling enclosure i created to suit the Gen 6 electronics.
The fan duct is glued onto the main cover as im too lazy to change it to a snap on, plus glued could have several advantages.

The cover snaps onto the base and a 40mm fan is attached to the fan duct.
This creates a wider higher pressure flow of air for cooling in the important places.

It provides good forced cooling keeping the board cool.

A simple sphere made from three interlocked rings I made one day to show the whole process to a friend.

The dimensions of the rings in the provided stl files are 60mm outer diameter, 20mm height and 3mm thickness. They have been generated with one face at every 2mm of the perimeter and also, a gap of 0.4mm in the slots which gave a nice fit for the rings printed by bot1334.

The zip file contains two more examples (40mm diameter, 5mm and 10mm height and, if I'm not wrong, 2mm thickness) however, I was not using any "gap" parameter for those so... they'll need some cleaning to fit properly.

UPDATE:
Replaced the OpenSCAD file with v2 version which includes a production plate for the 3 rings in one build.
(I find the multiple colors a much nicer option though...)

Also added:
- A set for three rings that should fit in a Cupcake, their diameter is 48mm, height 16mm (thickness and gap same as above) and they are distanced 2mm.
- Another set for larger build envelopes with huge dimensions (180x60x4dot5.zip)

I have NOT printed those, hope they work fine, good luck if you try them!

BTW, feedback (and picture too) for the big set is highly welcome !!! specially if it doesn't work so no one else will waste time, plastic, energy... trying it out !!!

Small snap-fit cable carrier with enclosed top.

All the other cable carriers I'd tried to print either fit poorly or were too large.

Each link is slightly larger than a dime.

Still need to make end terminations, and I will likely be making some different sized derivatives in the next week.
