Knitting Loom (150mm diameter, 26 pegs)

thingiverse

Knitting looms you can purchase work great, but my mom desired something that fell between the smallest and second-to-smallest sizes, with a higher density of pegs. This is my attempt at it using OpenSCAD. The scad file (attached) has modules to make it easy to render specific models for STL export: all, hoop, side peg, and all main pegs; just the hoop; one main peg; all needed main pegs (based on peg count variable); the one side peg; one main peg, one side peg, and a slice of the hoop with 2 main peg holes and side peg hole; STL for the main modules have been attached, prefixed with string "loom_" obviously: hoop, main_peg, side_peg, and test. Note that the design is meant to make it easy to change all dimensions. Next sub-project may be figuring out how to make it a customizable object. I'm extremely impressed by how well this turned out! If I had to adjust it, I would: 1) Make the radius a tiny bit larger. 2) Increase height of main pegs by 3mm. 3) Decrease height of side peg by 1mm. I'll hold off on adjustments until it's given a real test: making a hat! Print Settings Printer Brand: LulzBot Printer: TAZ 5 Rafts: Doesn't Matter Supports: No Resolution: .22mm Infill: 50% Notes: Print with brim for pegs: 1x loom_hoop 26x loom_main_peg I printed the 26 main pegs and one side peg at one time in ABS, and they turned out amazing. I have problems printing the hoop in ABS, so I'm going with PLA. So far, so good – will post the final print when it's assembled. Post-Printing Cleanup If you printed pegs with brim, you'll need to clean up the peg heads. For the hoop, only cleanup blemishes on the outside (sandpaper) and maybe the side peg hole. I just trimmed back the very outside of that hole, and the side peg went right in. Assembly Can push pegs in by hand or lightly tap them in with a mallet. I had a wooden mallet to gently tap them in after aligning each one. Very easy.
