DF95 DF65 IOM and others 3/4" PVC pipe RC sailboat stand - 4 position

thingiverse

I designed this stand based on David Jennings IOM boat stand design and also out of a bit of frustration that the only other full DF95 stands as of yet on Thingiverse are designed for metric sized EMT or PVC pipe. I design in metric 99% of the time myself, but for this one all measurements and parts are presented in Imperial units. Further, this design uses 3/4" Schedule 40 PVC plumbing pipe, and Imperial-sized hardware. Your slicer may need you to convert the prints to metric. For Cura slicer, i use the Barbarian plug-in to convert the parts to millimeters for printing. This stand will fit many boats besides a DF95 and there are several ways to make sizing adjustments by moving parts around and changing the PVC pipe lengths. It fits a DF65 with no problem as is. Heck, you don't even need to print a single part. You can make the arms and keel board out of wood using paper printouts of the side views of the parts as a template and use stacks of washers as spacers, etc. I have even included David Jennings original design 2D print plans as a PDF showing how to build his stand in wood (see picture and PDF in the files). Materials/Hardware needed: 3/4" PVC pipe - 13 feet, but allow a few feet more for waste 3/4" PVC tees - 6 pcs. 3/4" PVC caps (feet) - 4 pcs. 3" x 1/4" hex bolts - 2 pcs. 2-1/2" x 1/4" hex bolts - 4 pcs. 1-1/4"" x 1/4" hex bolts - 2 pcs. 1/4" nylon lock nuts - 8 pcs. 1/4" washers - 12 pcs. 1/8" thick x 1/2” width neoprene foam (adhesive backed) - 3 feet 1/4" thick x 1/2” width neoprene foam (adhesive backed) - 1 foot 1" double side Velcro strapping- 2 pcs. 10" long Flexible medium clear super glue (Mercury adhesives brand on Amazon) and accelerator Some substitutions: All non-printed materials should be available at most home improvement stores. I ordered the foam from Amazon. I do not recommend glossy gray household weatherstripping as it can stick to your boat (look for a matte finish on the foam, not glossy), but you may be able to find a good closed cell foam in your local store than I did. You can substitute some longer length bolts or use split lock washers and regular nuts. The cheaper zinc coated stuff is fine for most of us, no need to get higher strength or stainless hardware (except for saltwater use). Also, you could just use the 1/8" foam only, you must use it for the bulb cradle, but it is optional for the arms. The 1/4' thickness really helps match the hull shape though (you could use two layers of 1/8"). You can use any adhesive you like, but flexible medium clear super glue is thin enough to wick into the PVC joints without disassembly (this is important later). It is also not brittle like regular super glue. But don't worry, regular super glue is fine. **3/4" PVC pipe cut list (pictured in gallery as well)** Large Frame - 2 x Uprights - 22-1/4" 1 x Cross bar - 18" 1 x Handle - 18-1/4" 2 x Feet - 2" 2 x Tees 2 x Caps (feet) Small Frame - 2 x Uprights - 13" 2 x Cross bars - 15-1/2" 2 x Feet - 2" 2 x Connector pipes - 3" 4 x Tees 2 x Caps (feet) *****STL and Printed part details***** -All STLs have been uploaded here in their preferred print orientation for FDM printing. There is a usually a reason each one is placed a certain way, such as better accuracy, printability, strength, or cooling fan access. "Speed of part printing" was not considered in choosing orientation. PipeFitTest - An important print. Use this print to test the fit over your PVC pipe. The preferred fit is somewhat snug. After some light cleanup with a file or sandpaper to remove blips, the fit should be tight enough to where you might have to give it a twist to slide on a part with no looseness. If you have to resize the test part, then you may want to resize other prints that have pipe pass through them the same amount to get a good fit. (don't worry about resizing the spacers, they will probably be fine) KlbdMidTest & KlbdEndTest - These test prints are for checking the fit of the dovetail used to assemble the keel board pieces. Make sure the KlbdMidTest part is printed in the vertical orientation with supports, just like the large part is. If you need to change the fit, I would suggest only changing the size of the KlbdEndTest part. Once it fits, you can resize the full-size end part STL the same amount, if needed. You may have to do some light cleanup, but the fit of the parts should be snug enough to hand press together with no wobble. IOMarms STL- These arms are taken directly from the original wood designs and are generally sized for an IOM, but are not for a specific model. They will probably need customizing for your model. IOMarm.stp - Oh yeah! STEP file, baby! :) Use this arm as the starting point for your own custom arm. You will want to keep the rear features of the arm so you can save the PVC and handle hole locations. Also keep the clearance cut on the bottom to clear the small frame ends. Otherwise, redraw the arm parts however you like. DF95arms - Print 2. Sized for a DF95 and 1/4" foam padding. These arms will also work for a DF65 and about anything in between. Short Drill Jig- This is a good test print to make sure the long drill jig print will fit your PVC pipe. You will also use it to drill the holes in the small frame connector PVC pipe parts with this jig. A small brim will help it stick. Long Drill Jig - Used for drilling the large frame uprights. Definitely use a 1/2" or so brim on this print. It is a tall, narrow print, so it could get knocked loose while printing. ---DRILL JIG NOTE--- The PVC pipe layout picture in the gallery shows the distances from the ends of the PVC pipe for the hole locations. If you have drill press, mill, or other means to drill accurate holes, you can use those measurements and do not need to print the drill jigs! Pipe catch - Print 2. This part has a small button on the thin clip end to help the first layers stick to the bed. You can trim this off with a knife in a few seconds after printing. The helper disc is a separate part within the STL, so it can be deleted if you like, but it really helps! Cap- Print 6. These plug the upper ends of the PVC uprights and the handle. You may have to tweak the size of these or file a little off the fitting rings. This should be a snug fit by hand. Spacers - Print 16. Placing a couple of these back to back makes the middle spacer for the large and small frame connector bolt. Don't glue them together, they rotate against each other. Pipe clip - Print as needed. This is just a handy 3/4" pipe clip if you want to keep loose-fitting parts in place or use to build other clip-on parts of your own design. Tx Clip - Print 2. This set of clips are designed for a FlySky I6 transmitter. You have to insert the Tx flat and allow it to drop down. This snug fit prevent the Tx from being bounced out. I don't know if they will fit a different Tx, but you can modify them as needed. Keel Board middle - Print vertically as presented. I did not need a brim, but it may help if you have bed adhesion issues. This part needs very simple supports from the bed only. They go under the 2 flat sections on either side of the dovetail. It is designed for the DF95 bulb and 1/8" foam. Make sure you have used the test print! Keel board ends - Print 2. Knob - Print 2. Used on the keel board ends. These fit over the hex bolt head. Clamp - Print 2. These are a slip fit for easy adjustment, but can clamp firmly once you have the position you like. These parts have a recess to hold the Nylock nut. IOM Boat Stand pdf - This is the David Jennings original design which I used as the basis for this project Here are links to other metric sized stands based on David Jennings design. I did not use or remix any of their parts. I will surely credit them for NOT working for me and thus inspiring me to design something that did fit my needs. https://www.thingiverse.com/thing:3391502 for DF95/DF65 https://www.thingiverse.com/thing:2139038 for DF65/RG-65 https://www.thingiverse.com/thing:3250906 for IOM Also, many thanks to David Jennings himself for sparking the fires of so much creation based on his work.
