Ski Vise

prusaprinters

This ski vise approach was inspired by two existing 3D printed ski vise projects:https://www.thingiverse.com/thing:4188958https://www.printables.com/model/133890-ski-viceThe existing vises didn't have an attachment point for holding the center of the skis down (the tiedown point), lacked some documentation (like screw details), and used fasteners/screws that I couldn't easily purchase nearby. I designed a version that I can either temporarily clamp onto a table or board using quick-clamps instead of a hand-crank screw. I have been putting a 2"x12"x8' board on two sawhorses, then I used IRWIN quick clamps to attach the vises to the board. This has worked out really well. I'll add a make with photos of the parts in use. Ski ViseThis ski clamp system uses a common base design, which is either screwed into a surface or temporarily clamped in place using hand-clamps, like IRWIN quick clamps. Each base is attached to either a tiedown or a ski clamp with 2x 1" long screws. This is intended for using with 2 ski clamps (one at either end of the ski) and 1 tiedown in the middle of the ski, see any ski tuning/waxing demo video on youtube for reference.I used a mix of US and metric screws (which are much finer pitch than is ideal) because I had these already lying around. This will be annoying for everyone else... sorry!I have included lists of the printed parts and the non-printed parts below.Suggested use is:1x [BASE] + [TIEDOWN]2x [BASE] + [SC]I'm printing from PETG (black and Orange Prusa PETG) and TPU (NinjaTek NinjaFlex Midnight Black TPU Filament). You can choose different materials, I want to avoid PLA because I don't know how hot the iron will heat up the printed parts. The TPU is intended as a compliant material to be grippy and to avoid marring the skis.Note the printing orientations are designed to avoid issues with overhangs. There will be a thin skin printed across some holes, this is an intentional sacrificial layer to improve print quality and avoid support material.I have already plated the parts in PrusaSlicer. The TPU print was a bit complicated, and I needed to adjust the z-height lower than I usually use for PLA. I also loosened the tension on the extruder gears to where it barely closed onto the TPU. The filament stripped the first two times I tried to print the parts. When I finally printed the parts correctly, the TPU parts had a lot of stringing, but with some cleanup the parts all fit/work well together. [BASE] Base:[PETG] ClampBase.3mfThis is plated in PrusaSlicer as “1xClampBase.3mf”.4x [B] 3/4" screws + 4x [D] nuts for base reinforcement.2x [C] 1" screws for attaching accessory to each base.3x [I] Anti-scratch pads are stuck onto the bottom of each clamp base (or whatever other non-scratch material you want to use). This could also be a double sided VHB tape, if you want to mount the clamps permanently. Alternately, the bases can be screwed down. I have ~1" long screws. The holes are 4.25mm diameter, with 3 holes on each side of the base using a 1/2" spacing.[TIEDOWN] Tiedown point for ski bindings:[PETG] AccessoryRopeCatch.3mfThis is plated in PrusaSlicer as “1xAccessoryRopeCatch.3mf”.2x [D] nuts for attaching to each base.This part is designed to allow a length of [J] 3 mm diamater paracord to be used to pull down on the skis/bindings, in the same way that a tent can be secured with line tensioners (guy line tighteners).[SC] Ski clamp:[PETG] AccessorySkiClamp.stl & AccessorySkiClampSlide.stl (separate 3mf files also included)These two parts print-in place together.

Rubber pieces 3 & 4 are identical. These are plated as “1xSkiClampRubberPieces.3mf”.
