Trailer print setup Can be setup as single or dual wheel. Min of 190mm build volume Full print parts head on over to cults: https://cults3d.com/en/3d-model/various/scx6-trailer Can be setup as single or dual wheel. Dual wheel requires a min of 190mm. ** UPDATED parts ** 2022/02/10 - S Hook - to be used with chain links that you can find here: https://www.thingiverse.com/thing:3834608 - This is an option to keep the gate closed. I also found it helpful to keep the RC in tow in place. - When I printed this I laid it on its side and shrunk it down to 4mm heigh. The S hook will support the 4mm height. Let me know if you need a larger size. - Gate clip with key - there are a few different types of gate clips included. The one with the key is a recent add. Prevously it was pressure placed but found after many runs this wore away and didn’t hold well. The this new key option will require a wire of some sort to make sure you dont lose it, but works well - Strut top (shk-strut-55-top-v2) - after many runs I have found that the rubbing of the struts internals was wearing away at the screw pattern. It won’t fall apart, but there is the change that if your spring load is high enough it will cause it to slip into the thread and stick. The new strut top has a higher fit and less likely to pull through - Frame to axle backing (frame-axle-backing-bottom, frame-axle-backing-top) - There is nothing wrong with the original. It works as intended and holds steady. The new piece is two pieces that will allow it to extend and retract. I found that the original would push the wheels out during flex. This new piece should keep it moving more straight up and down. I have also started using “Super Lub O-Ring lubricant” to add inside the struts and axle. This will help slow down wearing of the filament. ** ORIGINAL ** Alignment - From the back (gate end) is how you would start your alignment of left/right side. When looking at each side, the parts align as expected. This will print with letters “L” and “R” (some with both) on them. This is “Left” and “Right”. For those with double letters, the First letter is the side it should be placed (when looking from the gate end). Example LR and RL would be “Left side, of the trailer as a whole; and right side while looking at the left face of the trailer Time to dial in your printer! For these parts to come together easily you need to make sure that your printer is printing within .1 of the target. You can still print, but you will need to do some post printing production to clean up some smaller parts to get them to fit together better. Built using CURA with Creality Ender series 220mm x 220mm x 300mm (all printed on ender5). Desired print size should be the same for the frame pieces (largest print bed space) are 190mm x 155mm and the dual tower support is 190mm in length. Axle parts: Housing 5mm Bearing holder Housing backing Frame parts: Frame parts are able to rotate to fit together. There is the ability to add 2mm steel rods through out where they join. Length range 40mm to 100mm. 40mm are the holes that line up with a bolt. There are two sizes to choose from. Suspension parts Shock struck and caps - approximate 55mm - choose your spring load according to what you will be towing. 4ppi is what is being used for testing. Spring length I am using is 64mm, to create a “preload” effect. Shock towers - Print the shock tower at a 45º angle for best print. This will fit over the frame and align holes. M3 will thread without nut; however a nut give more stability. Gate parts Hinges Gate - frame parts are used as gate parts. Your desired gate length is dependent on how long you want. 1 full size will work but may give you more of a steep ramp. 1 and 1/2 size together should be the best grade. Lock pin - one should work, but two is more ideal IMHO. You can use use the pin that allows for placement of a piece of filament, or you can screw in a M2x4mm screw. Filament requires gluing so be cautious you don’t glue the pin to the slot. Links: frame-axle-link - the link that goes from the frame to the axle Tire link - this link that goes between the two tires to keep them running in parrallel Frame-axle-backing-link - links from the inner frame to the axle backing. This has a stopper on it to prevent the tired from folding back too far. Parts list: M3 bolts and nuts - 6mm thru 30mm - Count will vary depending on how many frame pieces you are looking to connect. The lengths varies depending on your desired amount threading to place different nuts. Some like nylon where a little longer is needed to grab the nylon. Others like using blue locktite where a bit shorter can work just as well. I am using blue locktite in my demo. - 2mm steel rods - these are not necessary but do add a great deal of stability through the frame. There are option bulb parts that can be placed on joining frame parts to help as well. The various lengths are 100mm and 40mm. - Bearings - 12x18x4 - 5x11x4 - Stub axle: Axial Portal Stub Axle (2): Capra 1.9 UTB, AXI232008 - is what I am using. Supports a 4mm axle stub. At its size, a 3D printed pin would not hold the weight for long. - Axle pin - Axial AX30165 Pin, 2.5 x 12mm - is what I am using. Pin to hold the axle in place - Springs - your choice of spring load but length should be around 60-70mm in length. If you wish to buy shocks the length is approximate 55mm. You will have to remove the eyelet in order to fit in place. - Super Lube O-Ring lubricant: https://www.amazon.com/gp/product/B07C3CZ9CL/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&th=1 Hub and wheels This is setup to use a 4mm stub axle. What you choose to use for a hex hub, hub and wheel is your choice. The well is setup for use with 1.9 wheel (Axial stock 1/10 Nitto is in the picture). Unless you are printing in ABS or ASA, I recommend staying away from anything heavy.
