Screw print 1.1

First in a series of screw tests. I'm designing a 3D printed loom and am documenting the design process. I have already come up with the preliminary shape of the thing, but shall keep that under wraps until I'm ready to launch.

I am currently attempting to make a 3D printed screw for operating the hinge. Currently the loom is designed with a 20mm wide screw and screw hole so I am working from this for the time being.

The parameters I shall initially be varying are the thread size and the clearance (push). I have had good results printing a slot-together joint with a push of 0.125 so shall start from there.

Standard dimensions will remain the same throughout all variations of 1.x, specific dimensions will be changed according to the results. Print setting will most likely stay the same, at least until I start narrowing down on Specific Parameters and feel perhaps the printing quality needs to be improved.


Standard dimensions

thread size 20 x 20mm


Specific dimensions

Thread: 30
Push: 0.125


Print Settings

Layer height: 0.1mm
Shell Thickness: 0.4mm
Print Speed: 50mm/s


The Result


Have to turn it on and back a few times to get it to work, but after that it turns freely. I noticed some little ickle-wickle blobs on the inside of the bolt thread, which will maybe mean I need to do something to my printer settings, but I'm not sure what exactly yet. Nevertheless, I'm chuffed with the results of this test and will maybe try making a hinge next.

Tablet Weaving Lesson #1: Backstrap weaving a simple diamond motif

This is the first in a series of video and photo tutorials showing basic to advanced tablet-weaving concepts. These lessons shall each build on the last and hopefully take the viewer from simple diamond patterns up to more complicated double face pattern weaving with finer yarns and eventually onto the heady heights of brocading and other fancy techniques (just as soon as I learn how to do them myself). In this first lesson we'll learn the basic weaving steps involved in weaving a diamond pattern in the backstrap style. This lesson is meant for someone who has purchased a ready-made warp from me. The next lesson shall detail how to design and make this warp oneself. And we begin This is the basic pattern we are making. The woven band is tied to my waist with another strap. I am holding a small stick shuttle in my right hand which contains the weft. In front of me are the cards, each card has 4 warp threads going through it. The gap that you can see is called the ...

treble-cloth construction

I am currently in the process of designing a triple layered fabric. One layer shall carry conductive warp threads (one out of every three), another layer shall carry conductive weft threads (again, one out of every three) and a third layer shall lay between them and act as an insulator, keeping them apart and preventing unwanted contact between the two conductive layers. Constructing a treble cloth is a compicated process. The way that a treble cloth is woven is that first the face cloth is woven, then the centre cloth is woven, then the back cloth is woven. This is a draft for a treble cloth. The crosses indicate weaving marks for the cloth currently being woven, the dashes are lifts and are used to indicate shafts that are being lifted in the case of layers that are above the layer currently being woven. Blue is back, Red is front, Green is centre (All three layers are plain weave btw) The cloth is constructed like so 1: Back cloth is woven. All red and green marks are lif...

Hochdorf Two Hole Tablet Weaving

So, I saw a picture of a Hochdorf band woven by a member of the Historic Tablet Weaving group on Facebook. It looks like you can get more detailed patterning with this technique and you also get a nice sort of pebbled effect in the background weave. Anyway, so I googled it and found this webpage  The Warp Factor , with a nice explanation of how to weave this band and a good diagram to go with it that tells you exactly when and where to turn the cards. Nice stuff. This is my second attempt at Hochdorf patterning. First was in acrylic to work out the technique and the use of the board. Second in 2/60's silk, to make something extra special nice. This is my new weaving board. It's a bit scrappy but it does the job. there's a few wee annoying problems with it, but the next one will be better. This is how tension is maintained on the band, with a nice even consistency. The main part of the band is held as one with a bag full of weights. The selvedge table...
