Knitting Loom (150mm diameter, 26 pegs)

thingiverse

Knitting looms you can buy work great, but my mom wanted something that was between the smallest and second to smallest and had higher density of pegs. This is my attempt at it with 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 hoop: just the hoop main_peg: one main peg main_pegs: all needed main pegs (based on peg_count variable) side_peg: the one side peg test: 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 the design is meant to make it easy to change all dimensions. Next sub-project may be to figure out how to make it a customizable object. I'm super 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: make 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 1x loom_side_peg 26x loom_main_peg I printed the 26 main pegs and one side peg at one time in ABS. They turned out amazing. I have problems printing the hoop in ABS so am 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 should only need to cleanup blemishes on outside (sand paper) 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 in with a mallet. I had a wooden mallet I used to gently tap them in after aligning each one. Very easy.
