Some time ago I was searching for a device that allows precise removal of outer insulation (stripping of the cable jacket) from round cables. All tools I found were either adjustable in cutting depth but limited to rather large cable diameters or optimized for specific cable types with low diameters but with fixed cutting depths. Therefore, I decided to design my own tool, which is modular and has an adjustable blade. Here is my first version. The cutting depth can be adjusted. Maximum cutting depth is about 4 mm. It can operate down to a 2 mm cable diameter. One limitation is that the cable must withstand torsion when rotating the tool. Printing: All parts can be oriented in such a way that, in most cases, no support is required. The suggested orientation can be seen in the picture. Only printing the UpperPart requires support. Instead of printing the rollers, 2 Distanzhlsen (ID=3.6 mm, OD=7.0 mm, L=8 mm) can be used (https://www.reichelt.de/distanzhuelsen-kunststoff-8mm-dk-8mm-p44732.html?&trstct=pos_10&nbc=1) Additional parts for assembly: 3 pieces M3x6mm 2 for screwing the blade, 1 for fixing the die to the base. 1 piece M3x12mm and a washer for M3 for adjusting the cutting depth. 1 piece M3x16mm for connecting both parts. 2 more M3x16mm for the option with rollers. Spring D=5/16'' L=1 3/4'' (Approximately D=8 mm L=45 mm) Part of a 9mm cutter blade (3 segments). Required tools: Tread cutter for M3 Screwdriver Assembling instructions: - Clean all parts and check that all parts will move freely (especially the mount for the blade, move it some times by hand till it run smooth) - Cut M3 threads into all holes (only those with smaller diameters, of course) - Assemble the deep adjustment screw. Note the orientation of the AdjustWheel. - Assemble the blade. Note the mark for orientating the blade. Be very careful not to cut yourself! - Move the blade all the way up and put the cover in place. Note the orientation of the cover. Check that the blade will move out freely and retract the blade back for protecting your fingers in the next steps. - Put the die in place - Tension the spring and assemble both parts. Use: Set the blade to the required depth by doing several test cuts. To make a cut, place the cable into the tool and rotate it around the cable. Be careful with the tool as it has a sharp blade. All files are provided without any guarantee. Ideas for the next version: - Make it more compact. - Improve the stability of the blade cover - Move the blade out of the center to make the cut more controllable.
