This is really just a semi accurate place holder model for the components which come unassembled as part of the item purchased here from the link found in an applied science video. this is not my video or vendor link. I merely purchased the part and modeled its dimensions to facilitate mounting designs. I have also included a mounting plate to interface the spindle body to to the ender 3 V2 gantry plate, and a spindle drive motor mount plate designed to mount to the spindle body for the motors linked from amazon below: It requires a 6mm or less wide GT-2 -200 belt with a loop circumference of 186mm. It also happens that using an M5 tap on the top inlet hold of the spindle assembly will allow you to easily thread insert and obtain a strong fluid seal into the spindle body with a M5 hydraulic fitting like this;https://store.rc4wd.com/Hydraulic-Connector-M5-x-4mm-Tube-90deg_p_3079.htmlthese fittings then are compatible with 4mm hydraulic line used in RC excavators or some bicycle brake cables. You can find pumps and whole kits at places like the below link:https://magomhrc.com/en/trw-pump/1593-trw-brushless-pump-m5.htmlthe included wire guide model comes from a part purchased at this ebay listing.https://www.ebay.com/itm/174146231865?var=473046002157https://www.amazon.com/dp/B07XMFLSPB?psc=1&ref=ppx_yo2ov_dt_b_product_detailshttps://www.aliexpress.us/item/2251832167218225.html?gatewayAdapt=glo2usa4itemAdapthttps://www.youtube.com/watch?v=rpHYBz7ToII&ab_channel=AppliedScienceI took the drill chuck model from the one very graciously provided by Mikle. Drill chuck JT0This is a rotating drill head that allows high pressure fluid to be pumped through a long hollow electrode wich is kept rotating at a low speed by a gearmotor and GT2 belt assembly. this is ideal for doing deep high aspect ratio hole drilling with EDM if paired with an appropriate high pressure fluid pump and EDM power supply. the retaining ring was pulled directly from mcmaster. https://www.mcmaster.com/90030A104/Enjoy...
