Dremel CNC - useful MODs & AddOns

Nik's Dremel CNC is an incredible innovation.\r\nWhile building it, I made several modifications to get the most out of it!\r\nAll components are fully compatible with the original Dremel CNC.\r\n\r\n### TPU Foot\r\n- Print at least 4 of them with flexible material, simply slide them into the T-Slot Profile and you're good to go.\r\n\r\n\r\n\r\n### Spindle Carriage\r\n- extended range on X-axis (throats coupler)\r\n- limit switch mount on right, left, and top\r\n- fix screw holes for linear bearings on the back\r\nBy the way, for best mechanical/physical strength I recommend printing the part laying on its right or left side.\r\n\r\n\r\n\r\n### X-Axis Carriage right\r\n- chamfer instead of roundings for better printing results\r\n- hidden linear bearing\r\n- hidden T8-lead screw\r\n- room to fully throat the coupler\r\n- hidden stepper motor mount screws\r\n- holes to optionally secure linear bearings with 2 screws\r\nAvailable in 2 options:\r\nOption A) almost hidden stepper Motor for optimal performance.\r\nOption B) right Y-axis rod holder for more Z-axis range.\r\n\r\n### 10mm higher Y-axis rod holder & motor holder \r\nrod holder (with or without integrated emergency stop button) and motor holders (right with integrated limit switch) extended by 10mm in Z-axis.\r\nDepending on the spindle used, these parts give a bit more Z-axis range back.\r\n\r\n### 10mm higher X-axis carriage right & left\r\nIf the 10mm higher Y-axis rod/motor holders are not enough or as an alternative there are now also 10mm higher X-axis carriage parts to gain more Z-axis in case needed.\r\nIf you require them, this depends on your spindle and/or base board and/or waste board thickness.\r\n\r\n### updated 55mm spindle holder with optional integrated dust absorber\r\nThe new 55mm spindle holder allows for more spindle cooling and consists of one part only, as the clamp is directly part of it.\r\nThe main reason for the new spindle holder however is the newly introduced dust absorber that can be mounted optionally to this spindle holder\r\n\r\n### dust absorber with detachable skirt\r\n\r\n\r\n\r\n\r\n\r\nThe dust absorber sucks all the dirt coming while milling directly from its origin. it is built by means of several parts:\r\n- The main part to be mounted to the bottom of the updated 55mm spindle mount.\r\n- 2 clamps to support mounting the absorber to the spindle mount.\r\n- Together with the screwed on close, the absorber ends up having an integrated drain allowing for a very optimized air flow. The close also takes 3 round neodym magnets 6x2mm\r\n- Skirt holder also takes 3 round neodym magnets 6x2mm and which allows for quick detaching to easy access and replace your tools on the spindle.\r\nThe actual skirt gets mounted by means of a zip tie.\r\n- Skirt made to be printed of TPU. this flexible part channelizes the airflow for optimal absorbing\r\n\r\nThe absorber is made for a [flexible hose purchased on amazon](https://www.amazon.de/gp/product/B008DRXX2E/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1). outer diameter 30mm, inner diameter: 25mm\r\n\r\nUPDATE 31.03.2019:\r\nAdded Cable Chain mount for NEMA17 and T-slot alu rail\r\n\r\nUPDATE: 02.04.2019:\r\nAdded Y-axis rod holder with integrated emergency stop button. \r\n\r\nUPDATE: 21.04.2019:\r\nAdded 10mm higher parts for\r\nY-axis rod holders & Y-axis motor holders.\r\n\r\nUPDATE: 03.05.2019:\r\nAdded modular dust absorber\r\nUpdated spindle mount for dust absorber\r\nUpdated cable clamp with integrated dust hose holder\r\nAdded 10mm higher x-axis carriage parts left and right
