LowRider 3 CNC - HEIGHT EXTENSIONS for Makita 700 Series removable dust shoe - for 2.5" VAC HOSE (v1.2)

prusaprinters

ALERT: This is only for very shallow cuts in circumstances described below. It is not recommended for regular or normal use. For shallow cuts, you should first position the router bit as high into the collet as is proper and doable, and then if you still have too much height for your dust collection, temporarily using one of these extensions may help. Needlessly placing your bit too far down and your router too high up reduces rigidity, increases risk of breaking the bit,  and is detrimental to the LowRider's well designed performance. NOTE: this is the extension set for the 2.5" vac hose remix. (If you have a ~48mm vac hose, go here for that main original design, and here for that extension set remix.)   For those times when your project-specific use of your LowRider v3 is not going to need to cut deeply and you need/want your dust shoe to be closer to the work surface, I offer you three additional heights of the removable “vac-lower_2.5” (“scoop” part). This is the part that normally gets temporarily removed whenever you are doing a bit change. It slides onto the main “top” portion. The three new sizes have height increases in ¼" increments.Note: The “regular height” part, and all the other needed parts, are to be obtained from the prior remix available here.   FAQ:Q: Should folks with Makita still use the existing oneA: Yes. The taller ones are intended to be swapped in only when you are doing non-deep-cut jobs and want your dust shoe temporarily lowered!Q: Are the additional 3 taller remixes only intended for spindles with collets that end up being lower?A: These are intended for anyone who has need or want of a slide-on/slide-off scoop part of the shoe that is temporarily taller to get down closer to the work surface.(See a few more Q&A further down…) The following tips and Q&A are copied and pasted from the prior remix. Printing is just as with the original (quoting Ryan):"Print at 30%+ infill…. Vacuum hose gets a cable tie on the upper tool mount and one to the top of the core. It can take a bit of muscle to get the hose zipped in initially but it will soon conform to the curves and stay planted. The lower dust shoe is a snap on and off design that lets you easily change tools and get to the collet. Two Tool mount prints, one of each Top and Lower.”FAQ:Q: Did the Tool Mount “ring” get changed from the original?A: Yes. All three parts underwent changes in the remix. If you look closely at the Tool Mount, you will see that the portion that the hose zip ties to is protruding from a different position on the ring, and the curvature of the protrusion is edited to fit the larger diameter of the 2.5" hose.Q: Do I still need to print two of the Tool Mount “rings” like with Ryan's V1 original?A: Yes. As mentioned above, quoting Ryan, “Two Tool mount prints, one of each Top and Lower.”Q: What inside diameter (ID) is the opening (hose port)? What outside diameter (OD) of hose end will fit?A: The opening (hose port) is 62mm (ID). My Vacmaster shop vac hose (nominally 2.5") is approximately 61.75mm and fits perfectly. The actual conversion of 2.5" to millimeters is 63.5mm. Actual dimensions of hoses vary by brand. Measure yours first to know for sure. You may need to remix this to make it fit your hose, or design an adapter for it. My PayPal tip jar: https://paypal.me/design8studio   Various LowRider 3 CNC remixes:LowRider 3 CNC Collection View all my models and remixes on Printables:Design8Studio 3D models *Amazon product links are affiliate links.
