<p>This is a remix of the excellent pixel drilling jig by RiggsCasa used for drilling holes in 5/8" J-Channel from Lowes for mounting 12mm pixels. &nbsp;The original along with usage instructions is located on Cults3D and includes multiple spacing options - <a href="https://cults3d.com/en/3d-model/tool/christmas-j-channel-jig-for-ws2811">https://cults3d.com/en/3d-model/tool/christmas-j-channel-jig-for-ws2811.</a>&nbsp;</p><p>This is an edit of the 2.8in version which fits a string of 50 nodes nicely into a 12' stick. &nbsp;The hole was slightly undersized and is enlarged to 12mm so that forstner and brad point bits can be used. A chamfer was added as well to help center bits for the initial usage in case it prints undersized. &nbsp;The hole is now cut through the entire jig (hook portion) so that step bits can be used. &nbsp;The hook tolerance was tightened up a bit to pull the hook out of the drill path as much as possible. &nbsp;The base was thickened so that the jig can be used upside down in a shallow drill press vise, ideally with a forstner bit. &nbsp;An alignment window was added at 1.4" to assist with drilling the first hole. &nbsp;Finally, fillets were added to all vertical edges.</p>
